De Morgan, family

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.
