Joan Fish McCord (1930-2004) was an influential American criminologist. She graduated from Stanford University in philosophy and later completed a postgraduate research degree in sociology. Her early publications were with her first husband, the sociologist William Maxwell McCord. In 1987 she became the first female president of the American Society of Criminology. She is particularly known for experimental longitudinal studies of crime intervention programmes, often showing they had counterintuitive negative effects. She also studied the causes of juvenile delinquency and wrote about alcoholism and psychopathy. She is said to have made unique contributions by merging philosophical thinking with empirical social sciences.
