William Burnside

William Burnside (1852–1927) was a prominent British mathematician known for his contributions to group theory, particularly in the field of finite groups. He is well-known for Burnside's lemma, which provides a method to count the number of distinct objects under group actions, and for Burnside's theorem, which gives criteria for a group to be solvable. Burnside's work laid foundational principles that are still widely used in modern algebra and combinatorial species.
