Hamilton is well known for his contributions to evolutionary theory, particularly its mathematical formulation. Some of his ideas were popularised by Richard Dawkins in his book, The Selfish Gene.
The review says the book recounts
... the suicide of [Hamilton's] early collaborator, George Price (a mentally unstable individual, who was driven mad by his conversion from atheism to Christianity)It is interesting to compare this claim to the account of Price's life on Wikipedia which is quite different. It suggests Price's depression and resulting suicide was due to discouragement about the failure of his efforts to help the homeless.
