Miriam Markowitz in The Nation:
George Price was born a Jewish half-breed to parents who kept his Semitic side a secret; lived much of his life an aggressive atheist and skeptic of the supernatural; and died a Christian, twice converted, albeit, to his mind, a defeated one. Several years before he abandoned his career in a mission to shelter and comfort homeless alcoholics, he made a number of extraordinary contributions to evolutionary biology, a field in which he had no training. Educated as a chemist, Price had worked previously for the Manhattan Project on uranium enrichment, helped develop radiation therapy for cancer, invented computer-aided design with IBM and dabbled in journalism.
Shortly after Christmas 1974, Price slashed his carotid artery with a pair of tailor's scissors in his room in a London squat. John Maynard Smith, with whom Price published a paper that applied game theory to natural selection, was one of the few people, along with some of those homeless alcoholics, to attend his funeral. Also present was William Hamilton, the father of kin selection, which proposed that self-sacrificing behavior was able to evolve between related organisms because of the advantages conferred to their shared genes. Price used Hamilton's ideas about kin selection to derive his own equation, one that could explain selection at multiple levels of organization—the genetic level, as well as among individuals in kin groups and populations of unrelated others. The equation marked a breakthrough in the field: Price had provided a working mathematical model for the emergence of altruism in a theory of the world that took dogmatic self-interest as its first principle.
