George PeacockDied 8 Nov 1858 at age 67 (born 9 Apr 1791).English mathematician who, with fellow Cambridge undergraduates Charles Babbage and John Herschel brought reform to nomenclature in English mathematics. They formed the Analytical Society (1815) whose aims were to bring the advanced methods of calculus from Europe to Cambridge to replace the increasingly stagnant notation of Isaac Newton from the previous century. The Society produced a translation of a book of Lacroix in the differential and integral calculus. In 1830, he published Treatise on Algebra which attempted to give algebra a logical treatment, and which went at least partway toward the establishment of symbolic algebra. Instead of using only numbers he used objects, and showed the associativity and commutativity of these objects. |
