Abstract: The history of Behavioral Genetics and (now) genomics, viewed in cross-section, is a kaleidoscopic pattern derived from the individual histories of the psychology of individual differences, plant, animal, and human genetics, biology, evolution, anthropology, demography, biometry, sociology, jurisprudence, and some of their neighboring disciplines. There will be positive correlations between any two renditions of the historian’s task, but the idiosyncratic experiences of any two with the listed contributors to the pattern guarantees that the correlations may be modest, without invalidating either one

Key words: history of behaviour genetics, interdisciplinary science, individual contributions
