DeMorgan was born in Mandura, India, on June 27, 1806 where his father was employed by the East India Company. DeMorgan was blind in one eye and was bullied at school. He excelled in mathematics and completed a degree at Trinity College in Cambridge. He was appointed as the first professor of mathematics to the University of London (later called University College) in 1828 and taught there for thirty years. He published material on arithmetic, algebra, trigonometry, calculus, probability and formal logic. His contribution to mathematics has resulted in a set of laws that bear his name, two of which are: 1. not(p or q) = (not p and not q) 2. not(p and q) = (not p or not q). His work on propositional calculus and set calculus provides a formal basis for parts of the UML and analysis and programming.
