Jessie MacWilliams

Florence Jessie Collinson MacWilliams (4 January 1917 – 27 May 1990) was an English mathematician who contributed to the field of coding theory, and was one of the first women to publish in the field. MacWilliams' thesis "Combinatorial Problems of Elementary Group Theory" (or "Combinatorial Problems of Elementary Abelian Groups") contains one of the most important combinatorial results in coding theory, which is now known as the MacWilliams Identity.
