Gilbert Gottlieb

Gilbert Gottlieb (22 October 1929 – 13 July 2006) was an American psychologist.

After receiving his bachelor's and master's degrees from the University of Miami, he received his Ph.D. in the psychology - zoology program at Duke University. He observed the differences in bird development, by both observing egg hatching and manipulating variables important to bird development, including calls. Gottlieb's major contribution to the field of psychology was his theory of probabilistic epigenesis, which explains that there is no predetermined path to trait development. Gottlieb died 13 July 2006 in Raleigh, North Carolina, outlived by his wife, Nora Lee Willis Gottlieb, his children, Jonathan B.Gottlieb, Aaron L. Gottlieb, and Marc S. Gottlieb, and his grandchildren. Provided by Wikipedia
