**De Morgan's Law **
Who is the man behind De Morgan's Law? Read on and learn! The influential mathematician Augusta De Morgan was born in 1806 in Manure, India, where his father, a Lieutenant-Colonel in the Indian army, was temporarily stationed. De Morgan's first year of life was quite eventful: first he lost the ability to see from his right eye, and then he was uprooted from India to travel with his family back to England. De Morgan's early education led him to matriculate at Trinity College in 1823, where he earned his BA and would have received his MA, had he not morally objected to the theological exam required for the degree. He returned to London in 1826 and resisted his parents' wishes for him to enter the priesthood. He briefly considered medicine and law, but soon chose a different path, and in 1828 became the first mathematics professor at the University College of London. He resigned in 1831 on principle, was reinstated in 1836, and resigned again in 1861. His interests ranged from logic and mathematics to philosophy and astronomy, and his scholarly enthusiasm is evident from the vast number of articles, books, and other publications that he authored throughout his life time. His greatest accomplishments include mathematical induction, and his development of De Morgan's rule, which determines the convergence of a mathematical series. An abstract thinker, De Morgan made headway in the definition of a limit, and contributed greatly to the field of logic. He also founded the London Mathematical Society, and wrote much on the history of mathematics. De Morgan died in 1871, having made a rich contribution to mathematics. |
