Edward Chace Tolman (April 14, 1886 – November 19, 1959) was an American psychologist. Through Tolman’s theories and works, he founded what is now a branch of psychology known as purposive behaviorism. Tolman also promoted the concept known as latent learning first coined by Blodgett (1929) . A Review of General Psychology survey, published in 2002, ranked Tolman as the 45th most cited psychologist of the 20th century.
