Ludwig Reinhold Geissler and the founding of the Journal of Applied Psychology.

A significant number of earlier (1929-1987) and more recent (1991-2009) history of psychology textbooks have reported on the 1917 founding of the Journal of Applied Psychology (JAP). Although only G. Stanley Hall (1844-1924) was mentioned as the founder, the JAP had three financial founders: Hall, John Wallace Baird (1869-1919), and Ludwig Reinhold Geissler (1879-1932). They also served as co-editors for Volumes 1 and 2, and Hall and Geissler continued as co-editors for Volumes 3 and 4. Geissler's contributions to Volumes 1-4 far exceeded Hall's and Baird's. In unpublished autobiographical notes written in 1920, Geissler described himself as having "founded" and "established" the JAP with Hall's and Baird's aid; the evidence is consistent with that claim.
