Bill Hamilton (1936-2000). Caricature of the British evolutionary biologist William Donald 'Bill' Hamilton. Hamilton is known as one of the most significant evolutionary theorists of the 20th Century. He is best known for his theoretical work expounding a rigorous genetic basis for the existence of altruism, a key part of the development of a gene-centric view of evolution, and is considered one of the forerunners of socio-biology.
