Evelyn Merle Roden Nelson, mathematician, professor (born 25 November 1943 in Hamilton, ON; died 1 August 1987 in Hamilton, ON). A brilliant mathematical mind, Evelyn Nelson fought gender barriers in a discipline long dominated by men to become a rising star in the field both in Canada and abroad. She contributed to the fields of universal algebra, equational compactness and formal language theory. Nelson was particularly interested in applying universal algebra to the then-burgeoning field of computer science. She was a devoted teacher, sought-after research partner and the author of over 40 publications during what was a tragically short career.
