The 19th century saw the culmination of what we now call Classical physics and the high water mark of the mechanistic view of the universe. Clergy remained important contributors of science, even as the field (now called, for the first time, “science”) was becoming a viable way for laypeople to make a living. Two giants of this era were Gregor Mendel, the father of genetics (and a priest), and Angelo Secchi, the father of astrophysics (and also a priest).

A 1995 Journal for the History of Astronomy article by F. R. Stephenson and L. J. Fatoohi:
Abstract: During the seventeenth and eighteenth centuries, Jesuit astronomers at the Chinese court in Beijing observed many eclipses of the Sun and Moon. For most of these events the times of beginning, middle and end were measured and the magnitudes estimated. Summaries of virtually all of the observation made between A.D. 1644 and 1785 are still preserved. In this paper, that various solar eclipse measurements that the Jesuits made during the period are compared with computation based on modern solar and lunar ephemerides.

André-Marie Ampère: Enlightenment and Electrodynamics
Book- 406 pages
- Level: university
This 1995 biography of André-Marie Ampère is written by James R. Hofmann and published by Cambridge University Press. Ampère conducted pioneering studies of electricity, among other things (the unit of electrical current, the “Ampere” or “Amp” is named in his honor). This biography treats his scientific work in considerable detail. Ampère was Catholic, and he both valued his faith and also struggled with it at times. From a journal entry by Ampère after his final conversion (or reversion) to Catholicism:
God has revealed to me what my eternal salvation depends upon. Could I ever forget it? Great Saint Joseph, to whose intercession above all I owe this grace, Saint Mary, mother of God, whose name I received at my baptism and to whom I also have this inexpressible gift, always intercede before God that he may conserve it for me and that I might make myself worthy of it!
From the publisher:
In this authoritative biography, James Hofmann examines the extraordinary life of André-Marie Ampère, who made original, significant contributions to mathematics and chemistry and is renowned for his new branch of physics – electrodynamics. A member of the Académie des Sciences, and professor at the École Polytechnique, his accomplishments are remarkable in view of his tragic personal life. One of the elite of early nineteenth-century Parisian science, yet having no formal education, he embraced the scientific optimism of the Enlightenment, and the Catholic faith. This combination of intellectual expectation and emotional spirituality made Ampère’s genius both destructive and extraordinarily creative. This, the only biography available in the English language, illuminates the scientific contributions of an individual and his epoch, and provides a fascinating insight into the workings of the scientific mind.

Angelo Secchi, the Jesuit father of astrophysics
Article- 2000 words
- Level: all audiences
An article about the 19th-century Jesuit astrophysicist Angelo Secchi, published in August 2018 in the magazine America: The Jesuit Review. The author of the article is Adam Hincks, who is also an astrophysicist and a Jesuit. Secchi was a pioneer in the use of spectroscopy to study the stars and planets. Hincks writes:
It is a mark of genius to come up with questions that are obvious in retrospect but that nobody had ever thought of asking before. The Jesuit astronomer Angelo Secchi (pronounced “sekki”), whose 200th anniversary of birth is being celebrated this year, had that talent.
Before Secchi, astronomers were mainly interested in figuring out exactly where stars and planets were. This was important for navigation, and therefore commerce, and intricate mathematical systems were developed to track the motions of the heavens above in order to guide the motions of ships below. But Secchi asked a new question: What are stars and planets? With this question, the brand-new disciplines of astrophysics and planetary sciences were launched.
This may be Secchi’s most famous legacy; but taken in isolation, it does not do justice to his many talents and to a life full of discovery, invention, public service—and even political intrigue.

Astronomy on the Frontier
Article (blog post)- 1200 words
- Level: all audiences
Christopher Graney writes on The Catholic Astronomer blog about the first bishop of Vincennes, Indiana, Simon Guillaume Gabriel Bruté de Rémur (1779-1839), and his library. The library contained a significant collection of works on science, which Bishop Bruté hauled all the way to the American frontier from France. Graney writes:
It turns out Bruté had been a top-notch student of science—one of the best students in his class at the medical school in Paris. So of course his library would include quite a bit of material on a variety of sciences, including astronomy. Still, Indiana was being settled at the time, and was pretty rough country: the land of Abraham Lincoln’s youth…; a land that had only become a state twenty years earlier; a land from which the Potowatami Indians were being forcibly evicted while Bruté was bishop, passing only a hundred miles to the north on a “Trail of Death.” Was it really worth the trouble and cost to haul crates of science books to this country, all for a church library? especially for a guy who apparently owned so little other stuff of worth that a decent set of clothes had to be borrowed for his burial! Obviously, in the opinion of the first bishop of Vincennes, it was indeed worth it (and worth it to have some up-to-date astronomy books, too)…. It is worth knowing that Bishop Simon Guillaume Gabriel Bruté de Rémur cared about having science books, including astronomy books, in the rough-and-tumble country of 1830’s Indiana. In the U.S.A., at least, we tend to value a little more those things our forebears valued.
James Clerk Maxwell – Science and Faith
Article (two letter excerpts)- 350 words
- Level: all audiences
James Clerk Maxwell is one of the most important figures in the history of science. Students in physics courses everywhere study “Maxwell’s Equations” that mathematically describe electromagnetic waves. These waves include light, radio, x-rays, etc. They are how astronomers learn about the universe and they are the basis of all wireless communication technology, including smart phones.
Maxwell was a devout Christian who spoke of his faith in many of his letters. Below are two excerpts from letters which contain direct references to both his scientific work and his faith.
The first is from a draft of a letter in 1875 regarding membership in “The Victoria Institute”:
I think men of science as well as other men need to learn from Christ, and I think Christians whose minds are scientific are bound to study science that their view of the glory of God may be as extensive as their being is capable of. But I think that the results which each man arrives at in his attempts to harmonise his science with his Christianity ought not to be regarded as having any significance except to the man himself, and to him only for a time, and should not receive the stamp of a society….
The second is from a letter of response to the Bishop of Gloucester and Bristol, who had written to Maxwell wondering whether the creation of the sun after the creation of light in Genesis 1 can be explained through the newly-developed physics of light. Maxwell replies by noting, in part, that what is new physics now may be discarded wrong ideas later:
If it were necessary to provide an interpretation of the text in accordance with the science of 1876 (which may not agree with that of 1896), it would be very tempting to say that the light of the first day means the all-embracing aether… But I cannot suppose that this was the very idea meant to be conveyed by the original author to those for whom he was writing.
But I should be very sorry if an interpretation founded on a most conjectural scientific hypothesis were to get fastened to the text in Genesis … The rate of change of scientific hypothesis is naturally much more rapid than that of Biblical interpretations, so that if an interpretation is founded on such an hypothesis, it may help to keep the hypothesis above ground long after it ought to be buried and forgotten.
At the same time I think that each individual man should do all he can to impress his own mind with the extent, the order, and the unity of the universe, and should carry these ideas with him as he reads such passages as the 1st Chap. of the Ep. to Colossians (see Lightfoot on Colossians, p.182), just as enlarged conceptions of the extent and unity of the world of life may be of service to us in reading Psalm viii.; Heb. ii 6, etc.

Giuseppe Piazzi and the Discovery of the Proper Motion of 61-Cygni
Fr. Giuseppe Piazzi
- Article
- 8 pages
- Level: university
Fr. Giuseppe Piazza discovered the proper motion of the star 61 Cygni at the end of the eighteenth century. A star’s proper motion is its motion across the sky compared to other stars. The position of 61 Cygni, a star that is faint but visible to the naked eye, changes measurably over the course of a year. A star whose position changes like this must be a relatively nearby star. In this 1990 article in the Journal for the History of Astronomy, Georgia Fodera Serio of the Palermo Observatory discusses the story of Fr. Piazzi and his “flying star”, and writes on the importance of Piazzi’s discovery. Serio notes that Piazzi “abandoned the old paradigm that ‘brightness implies nearness'”. This was an important step for astronomers, who previously had supposed that those stars that appear brighter in our night sky are nearer to us. In the 1830s the German astronomer Friedrich Wilhelm Bessel would measure the distance to 61 Cygni using annual parallax, finding that it is about 10 light years away. This was the first direct measurement of the distance of any star other than the sun.

Vol. I, fol. 174v (Bruni, scribe)
The Assessor of the Holy Office has referred the request of Giuseppe Settele, Professor of Optics and Astronomy at La Sapienza University, regarding permission to publish his work Elements of Astronomy in which he espouses the common opinion of the astronomers of our time regarding the earth’s daily and yearly motions, to His Holiness through Divine Providence, Pope Pius VII. Previously, His Holiness had referred this request to the Supreme Sacred Congregation and concurrently to the consideration of the Most Eminent and Most Reverend General Cardinal Inquisitor. His Holiness has decreed that no obstacles exist for those who sustain Copernicus’ affirmation regarding the earth’s movement in the manner in which it is affirmed today, even by Catholic authors. He has, moreover, suggested the insertion of several notations into this work, aimed at demonstrating that the above mentioned affirmation [of Copernicus], as it is has come to be understood, does not present any difficulties; difficulties that existed in times past, prior to the subsequent astronomical observations that have now occurred. [Pope Pius VII] has also recommended that the implementation [of these decisions] be given to the Cardinal Secretary of the Supreme Sacred Congregation and Master of the Sacred Apostolic Palace. He is now appointed the task of bringing to an end any concerns and criticisms regarding the printing of this book, and, at the same time, ensuring that in the future, regarding the publication of such works, permission is sought from the Cardinal Vicar whose signature will not be given without the authorization of the Superior of his Order.

Considered one of the greatest scientists in history, Gregor Mendel was the first person to map the characteristics of a living things successive generations, thus forming the foundation of modern genetic science. In Gregor Mendel, distinguished novelist and biologist Simon Mawer outlines Mendel’s groundbreaking research and traces his intellectual legacy from his discoveries in the mid-19th century to the present.
In an engaging narrative enhanced by beautiful illustrations, Mawer details Mendels life and work, from his experimentation with garden peas through his subsequent findings about heredity and genetic traits. Mawer also highlights the scientific work built on Mendels breakthroughs, including the discovery of the DNA molecule by scientists Watson and Crick in the 1950s, the completion of the Human Genome Project in 2003, and the advances in genetics that continue today.
Click here for the Field Museum website for the Gregor Mendel: Planting the Seeds of Genetics exhibit. From the website:
In an abbey garden, Mendel planted the seeds for the science of heredity.
Born to poor tenant farmers in the Austro-Hungarian Empire, Gregor Mendel joined the Abbey of St. Thomas in 1843, at age 21. The Abbey was a dream come true for a budding scientist. A vibrant center of research, its friars were active in the sciences, linguistics, literature and philosophy. The Abbey made it possible for Mendel to attend the University of Vienna and to read widely in a library that contained 30,000 books.
Mendel had diverse interests—astronomy, meteorology, physics, botany, and mathematics. He was one of the first scientists to use rigorous experiments and mathematical analysis as a means to study biology.
In 1856, Mendel launched an ambitious series of experiments with Pisum sativum—the garden pea. Eight years and approximately 28,000 pea plants later, Mendel published the results of his grand experiment. His methods were so advanced and his results so groundbreaking that no one realized how his discovery would eventually revolutionize science.
After being elected Abbot in 1868, Mendel had little time for science. He may have been disheartened by the lack of reaction to his pea paper, but he knew that his discovery was important. Not long before his death in 1884 he told a scientific colleague, “My time will come.”
Mendel was right. In 1900 three European botanists rediscovered his work and set off a scientific explosion. The field of genetics was born and Mendel is considered its founding father.

Br. Guy Consolmagno, S. J., an astronomer with the Vatican Observatory, discusses Jesuits and their many contributions to science in an article and in a talk (on video). Br. Consolmagno notes:
A Jesuit scientist, supported by the order, is often not tied to a three-year funding cycle or six-year tenure review. Thus we have the time – it may take decades – to catalogue double stars, seismic velocities, or patterns in climate or terrestrial magnetic fields. Jesuits, for instance, invented the basic taxonomy of the plants of India. But this sort of science often meant that their work was unappreciated by their immediate peers. Famously in the 19th century the Whig historian and politician Thomas Macaulay sneered that the Jesuits “appear to have discovered the precise point to which intellectual culture can be carried without risk of intellectual emancipation” and that being a Jesuit “has a tendency to suffocate, rather than to develop, original genius.”

The request was denied; Settele appealed to Pope Pius VII. This article by Fr. Juan Casanovas, an astronomer with the Vatican Observatory, provides a brief historical background on and summary of the actions surrounding this event. Casanovas writes:
It is a merit of Settele that he insisted on obtaining the imprimatur. If he had just rewritten his textbook to say: supposing or in the case the earth moves around the sun… there would have been no difficulty. However he insisted and his insistence earned freedom for all subsequent writers of astronomy. Settele didn’t give in to the requests of the Pope’s palace “maggiordomo”.

This book by Edward Edelson is part of the Oxford Portraits in Science series for young adults. The general editor of this series is Owen Gingerich, a historian of science with Harvard University, and an astronomer with the Harvard-Smithsonian Center for Astrophysics. This book discusses the work and life of Gregor Mendel, who is recognized today as being the founder of the modern science of genetics. Mendel was a monk and later abbot of the Augustinian monastery at Brno in the Czech Republic. Edelson writes:
[In] an Easter sermon. Mendel took special note of the way that Christ appeared to Mary Magdalen when he rose after his crucifixion: as a gardener. He wrote that “the gardener plants seed or seedlings in prepared soil. The soil must exert a physical and chemical influence so that the seed of the plant can grow. Yet this is not sufficient. The warmth and light of the sun must be added, together with rain, in order that growth may result.” Mendel used this image from the world of nature to illustrate how “the germ of supernatural life, sanctifying grace, is put into the soul of man.” So even as a priest, Mendel referred to his work with plants.

From the publisher, Oxford University Press:
When Gregor Mendel passed away in 1884, not a single scholar recognized his epochal contributions to biology. The unassuming abbot of the Augustinian monastery in Brno (in today’s Czech Republic) was rediscovered at the turn of the century when scientists were stunned to learn that their findings about inheritance had already been made by an unknown monk three decades earlier. A dedicated researcher who spent every spare hour in the study of the natural sciences, Mendel devised a series of brilliantly simple experiments using a plant easily grown on the monastery’s grounds–the garden pea. In the course of just a few years he made the famous discoveries that later became the centerpiece of the science of heredity. In an entertaining and thoroughly informed narrative, Edward Edelson traces Mendel’s life from his humble origins to his posthumous fame, giving us both a brief introduction to the fascinating science of genetics and an inspired account of what a modest man can accomplish with dedication and ingenuity.

Numbers suggests that we must first dispense with the hoary myths that have masqueraded too long as historical truths. Until about the 1970s, the dominant narrative in the history of science had long been that of science triumphant, and science at war with religion. But a new generation of historians both of science and of the church began to examine episodes in the history of science and religion through the values and knowledge of the actors themselves. Now Ronald Numbers has recruited the leading scholars in this new history of science to puncture the myths, from Galileo’s incarceration to Darwin’s deathbed conversion to Einstein’s belief in a personal God who “didn’t play dice with the universe.” The picture of science and religion at each other’s throats persists in mainstream media and scholarly journals, but each chapter in Galileo Goes to Jail shows how much we have to gain by seeing beyond the myths.

Pioneer Work in Opening the Medical Profession to Women – Autobiographical Sketches by Dr. Elizabeth Blackwell
Book- 264 pages
- Level: high school and above
This 1895 autobiography of Elizabeth Blackwell, the first woman to receive a medical degree in the United States. Blackwell concludes her autobiography with the following:
It has become clear to me that our medical profession has not yet fully realised the special and weighty responsibility which rests upon it to watch over the cradle of the race; to see that human beings are well born, well nourished, and well educated. The onward impulse to this great work would seem to be especially incumbent upon women physicians, who for the first time are beginning to realise the all-important character of parentage in its influence upon the adult as well as on the child — i.e. on the race.
To every woman, as well as to every man, the responsible function of parentage is delegated. Our nature is dwarfed or degraded if the growth which should be attained by the exercise of parentage, directly or potentially, be either avoided or perverted.
The physician knows that the natural family group is the first essential element of a progressive society. The degeneration of that element by the degradation of either of its two essential factors, the man or the woman, begins the ruin of a State.
It is a source of deep gratitude in a long medical life to have been enabled by physiological knowledge, as well as experience, to perceive the true point of view from which the special nature of man and woman must be regarded. It is well worth the efforts of a lifetime to have attained knowledge which justifies an attack on the root of all evil — viz. the deadly atheism which asserts that because forms of evil have always existed in society, therefore they must always exist; and that the attainment of a high ideal is a hopeless chimera.
The study of human nature by women as well as men commences that new and hopeful era of the intelligent co-operation of the sexes through which alone real progress can be attained and secured. We may look forward with hope to the future influence of Christian women physicians, when with sympathy and reverence guiding intellectual activity they learn to apply the vital principles of their Great Master to every method and practice of the healing art.
Though a Christian, and though she worked with Catholics on various occasions, Blackwell “blessed Heaven for the fact” that she was a Protestant, an view which shows forth periodically within the book.

Book (and book excerpt)- 448 pages (excerpt is 3200 words)
- Level: high school and above
Nicolás Patricio Esteban Wiseman was Cardinal and first Archbishop of Westminster upon the re-establishment of the Catholic hierarchy in England and Wales in 1850. His discussions of religion and science in the early nineteenth century became well-known.
The complete text of Wiseman’s lectures is available from Google Books (click here).
Click here for an excerpt selected by the Interdisciplinary Encyclopedia of Religion and Science (Inters.org), which is edited by the Advanced School for Interdisciplinary Research, operating at the Pontifical University of the Holy Cross, Rome, and directed by Giuseppe Tanzella-Nitti. In this excerpt Wiseman defends Rome as a center of learning and writes of various early figures in the church who promoted the study of mathematics or the natural world, including Clement of Alexandria:
Clement of Alexandria … devoted several chapters of his learned Stromata to the vindication of his favorite studies. He observes very justly, that “varied and abundant learning recommends him who proposes the great dogmas of faith, to the credit of his hearers, inspiring his disciples with admiration, and drawing them towards the truth which is in like manner the opinion of Cicero, when he says, “magna est enim vis ad persuadendum scientiae.” Clement then illustrates his argument by many quotations from the Holy Scriptures, and from profane authors. I will read you one remarkable passage.
“Some persons, having a high opinion of their good dispositions, will not apply to philosophy or dialectics, nor even to natural philosophy, but wish to possess faith alone and unadorned: as reasonably as though they expected to gather grapes from a vine which they have left uncultivated. Our Lord is called, allegorically, a vine, from which we gather fruit, by a careful cultivation, according to the eternal Word. We must prune, and dig, and bind, and perform all other necessary labor. And, as in agriculture and in medicine, he is considered the best educated who has applied to the greatest variety of sciences, useful for tilling or for curing, so must we consider him most properly educated, who makes all things bear upon the truth; who from geometry, and music, and grammar and philosophy itself, gathers whatever is useful for the defence of faith. But the champion who has not trained himself well, will surely be despised.”
These words, I must own, afford me no small encouragement. For if, instead of geometry and music we say geology, and ethnography, and history, we may consider ourselves as having, in this passage, a formal confirmation of the views which we have taken in these Lectures, and an approbation of the principles on which they have been conducted.
Life of Mendel
- Book
- 336 pages
- Level: high school and above
This biography of Fr. Gregor Mendel was written by Hugo Iltis in the early twentieth century (the introductory letter is dated January 1924). Iltis laments that the records Mendel left behind “were almost exclusively concerned with concrete facts… he never kept a diary, and his letters throw little light on the inner man”, so the biography is very factual in nature. And, given the time that has passed since Iltis wrote this biography, parts of the book are dated. Nevertheless, the book still provides a good in-depth look at Mendel’s life and his scientific work. Mendel, an Augustinian monk, is of course known for his pioneering work in essentially founding the science of genetics, but Iltis’s work reveals other scientific interests as well—Mendel observed the sun telescopically, for example, and kept a record of sunspots. The academic publisher Routledge issued a reprint of Iltis’s biography in 2018. Regarding Life of Mendel, Routledge states:
First published in 1932. The widespread influence of Gregor Johann Mendel’s work and his own remarkable destiny combine to arouse interest in the personality and the life of this investigator who, little known in his lifetime, was one of the pioneers of science. This comprehensive biography of the life and work of Mendel will be of great interest to historians and scientists.

From the publisher, Abrams Books:
The only picture book available about the father of genetics and his pea plants!
How do mothers and fathers—whether they are apple trees, sheep, or humans—pass down traits to their children? This question fascinated Gregor Mendel throughout his life. Regarded as the world’s first geneticist, Mendel overcame poverty and obscurity to discover one of the fundamental aspects of genetic science: animals, plants, and people all inherit and pass down traits through the same process, following the same rules.
Living the slow-paced, contemplative life of a friar, Gregor Mendel was able to conceive and put into practice his great experiment: growing multiple generations of peas. From observing yellow peas, green peas, smooth peas, and wrinkled peas, Mendel crafted his theory of heredity—years before scientists had any notion of genes.
Children will be inspired by Gregor’s neverending search for knowledge, and his famous experiments are easy to understand as an introduction to genetics.

Elizabeth Blackwell: First Woman Physician
Book- 112 pages
- Level: all audiences
This book on Elizabeth Blackwell was written by Tristan Boyer Binns and published by Scholastic in 2005. From the jacket cover:
At a time when only men were supposed to become doctors, Elizabeth Blackwell earned a medical degree in 1849 from Geneva Medical College in New York. She was the first woman in the United States to ever earn such a degree. After graduating, she struggled to find ways to expand her medical knowledge. She traveled to France to study at La Maternite hospital in Paris. A serious eye infection forced Blackwell to lose her left eye and ended her dreams of becoming a surgeon. In 1853, she founded a free dispensary in New York City, the first of her many efforts to help provide women and children with better health care. Throughout her career, she fought tirelessly to help other women gain opportunities in medicine.
This book is written for school-age readers, but it does unflinchingly discuss health problems in the nineteenth century, including Blackwell’s eye infection, contagious diseases, problems related to sexual health and disease, and so forth.
