De Morgan established the logical footing of mathematical induction, and his interest in algebra led to the formulation of the de Morgan Laws (see Boolean algebra). He did not excel at school, having lost the sight of an eye shortly after birth, but nevertheless went to Cambridge U when aged sixteen. He refused to take the theological test required for an MA and, as a result, was not eligible for a fellowship. In 1828, after studying law at Lincoln's Inn for a year, he successfully applied for the chair of mathematics at the newly founded UCL despite his lack of mathematical publications. He was a major contributor to the popular Penny Cyclopedia, contributing over 700 articles. He has been described as a ‘dry, dogmatic pedant’ and during his career he twice resigned his chair on matters of principle—being re-appointed each time—and he refused to allow his name to be put forward for election to the Royal Society. He was the first President of the LMS. A lunar crater is named after him.
