Administrative / Biographical History

Augustus de Morgan was born at Madura, India in 1806. In February 1823 he entered Trinity College, Cambridge, where he graduated in 1827. In 1828 he was appointed Professor of Mathematics at University College London. With a short break from 1831-1836, he retained this post until his retirement in 1861. He was married in 1837 to Sophia Elizabeth Frend. During his lifetime de Morgan wrote thousands of books and articles on mathematics, logic, philosophy and many other subjects, though his outstanding contributions were made in the field of logic. He died in 1877. His son, William Frend de Morgan, was born in London in 1839. He made his name initially in the arts and crafts movement, designing pottery tiles using medieval or art nouveau designs. Later he became a novelist with such success that he eventually abandoned his artistic career. Collections of de Morgan's designs are held in the Victoria and Albert Museum and the William Morris Gallery. He died in 1917.

Augustus De Morgan was born in Madras, India, but his family travelled to England in 1807, a few months after his birth. He was the son of John De Morgan, a colonel in the Indian Army, and Elizabeth Dodson, the daughter of the mathematician Dodson. Augustus went up to Trinity in February 1823, and received his BA degree in 1827. De Morgan contributed over 700 articles to the 'Penny Cyclopoedia'. He was appointed the first professor of mathematics at the institution which went on to become University College London, and was heavily involved in the arrangement for the establishment of the College. Augustus De Morgan died in 1871. Sophia De Morgan and Augustus De Morgan had seven children: Elizabeth Alice who was born in 1838, and who died of consumption in 1853; William Frend who was born in 1839; George Campbell who was born in 1841 and who died of consumption in 1867; Edward Lindsey who was born in 1843 and who died in 1877 in South Africa following a fall from his horse; Anne Isabella who was born in 1845, married R.

She also wrote a book of reminiscenses called "Three Score Years and Ten". Her mother was a member of the Blackburne family. Augustus De Morgan's youngest daughter Mary was a published and acclaimed writer who specialised in fairy stories. Her book 'The Necklace of Fiorimonde', illustrated by Walter Crane was published in 1880. She died in Cairo in 1906. William Frend De Morgan married Evelyn Pickering in 1887 - they had no children. Augustus' brother Edward Lindsey and his family moved to South Africa. He was killed in a riding accident in South Africa, his widow Ada, and their children Mary (known as Molly or Minda), Augustus, Millicent and Campbell moved back to London and lived close to William and Evelyn in Chelsea.
