Sidney L. Pressey
Pressey joined Ohio State in 1921, and stayed there until he retired in 1959. He continued publishing after retirement, with 18 papers between 1959 and 1967. He was  a cognitive psychologist who "rejected a view of learning as an accumulation of responses governed by environmental stimuli in favor of one governed by meaning, intention, and purpose". In fact, he had been a cognitive psychologist his entire life, well before the "mythical birthday of the cognitive revolution in psychology".
