On March 31, 1934, in Reading, PA, delegates from 14 high school science clubs from all parts of the Commonwealth approved a constitution for the PJAS organization. The Pennsylvania Junior Academy of Science had become a reality. Dr. Otis W. Caldwell from Columbia University served as an official delegate of the AAAS and welcomed the new group. Pennsylvania was added to the states of Indiana, Texas, Alabama, Arkansas, and others that already established junior academies of science. The first PJAS State Director was Dr. Karl F. Oerlein of the California State Teachers College in California, PA. He continued his office until 1941.
