Cushman was widely known within the microprocessing industry for his influential writings in Electronic Design News about microprocessors during its infancy in the early 1970s, through its period of rapid growth and development in the 1980s.
His articles, collectively, chronicle the birth and early milestones of microprocessors and, at the time, helped bridge technical development with applications.
In 1959, after serving as Associate Editor of Automatic Control, Cushman accepted a position as Public Relations Director of Daystrom, Inc., San Diego,[4] which was acquired by Schlumberger in 1962, but continued to operate as a wholly owned subsidiary.
[5] Cushman had retired as Senior Editor at Cahners Publishing,[1] a longtime division of Reed Elsevier and, at the time, parent of EDN.
At the age of fifteen — from January 21, 1939, to June 1, 1939, and from July 17, 1939, to September 23, 1939 — Cushman had acted in the Broadway play, The American Way, in the role of Young Alex Hewitt at that RKO Roxy Theatre.
