APA was founded in 1892, but it wasn't until 1946 that the association grew to such a size that a chief executive officer (CEO) was needed to manage its day-to-day functions. Before then, the business of the association was run by the secretary-treasurer out of his or her personal office. APA's former CEOs and the years they served are:

* Dael Wolfle, 1946-50

* Fillmore H. Sanford, 1950-56
