Edward Bransfield, (born c. 1785—died 1852), English naval officer believed to have been the first to sight the Antarctic mainland and to chart a portion of it.
Master aboard HMS Andromache at Valparaíso, Chile, he was appointed to sail the two-masted brig Williams in order to chart the recently sighted South Shetland Islands, which lie near the Antarctic Peninsula. Under Bransfield’s command, the Williams arrived at the South Shetlands in January 1820, landed on King George Island to take formal possession, and coasted past Deception Island. Turning southward into what is now called the Bransfield Strait, he sighted and charted “high mountains, covered with snow,” now Mounts Bransfield and Jacquinot on the Antarctic mainland (January 30, 1820). The charts survive in the hydrographic department of the British Admiralty at Taunton, Somerset, England. – Encyclopedia Britannica
Bertrand Arthur William Russell, 3rd Earl Russell, OM FRS (/ˈrʌsəl/; 18 May 1872 – 2 February 1970) was a British philosopher, logician, mathematician, historian, writer, essayist, social critic, political activist, and Nobel laureate. At various points in his life, Russell considered himself a liberal, a socialistand a pacifist, although he also confessed that his sceptical nature had led him to feel that he had “never been any of these things, in any profound sense.” Russell was born in Monmouthshire into one of the most prominent aristocratic families in the United Kingdom.
In the early 20th century, Russell led the British “revolt against idealism“. He is considered one of the founders of analytic philosophy along with his predecessor Gottlob Frege, colleague G. E. Moore and protégé Ludwig Wittgenstein. He is widely held to be one of the 20th century’s premier logicians. With A. N. Whitehead he wrote Principia Mathematica, an attempt to create a logical basis for mathematics, the quintessential work of classical logic. His philosophical essay “On Denoting” has been considered a “paradigm of philosophy”. His work has had a considerable influence on mathematics, logic, set theory, linguistics, artificial intelligence, cognitive science, computer science (see type theory and type system) and philosophy, especially the philosophy of language, epistemology and metaphysics. – Wikipedia
