In this letter, Dr. Boetler thanks Arnold O. Beckman for donating several components of an EASE computer to the University of California Los Angeles's Department of Engineering. Dr. Boetler also thanks Dr. Beckman specifically for his work with professor of Engineering Tom Rogers and his graduate student Louis G. Walters. At the time, Dr. Boetler was the dean of the College of Engineering at UCLA.

Beckman Instruments' analog computers were being produced by their Berkeley Division as early as 1953. The company produced analog computers -- also called automation, data reduction, or data handling systems -- for the petroleum, aerospace, and defense industries. Beckman Instruments eventually stopped producing these systems after their cost and the time required to customize them kept them from being widely adopted.
