Harold Cohen’s early work exhibited at LACMA

Cohen’s exhibition, Three Behaviors for the Partitioning of Space, at the Los Angeles County Museum of Art presented his early, pre-AARON computer drawings. This came after Cohen arrived at the University of California, San Diego as a visiting lecturer in 1968, becoming professor and department chairman in 1969, and learned programming from Jef Raskin.
