Grace Hopper - Retirement

Retirement

Hopper retired from the Naval Reserve with the rank of commander at the end of 1966. She was recalled to active duty in August 1967 for a six-month period that turned into an indefinite assignment. She again retired in 1971, but was asked to return to active duty again in 1972. She was promoted to captain in 1973 by Admiral Elmo R. Zumwalt, Jr.

After Rep. Philip Crane saw her on a March 1983 segment of 60 Minutes, he championed H.J.Res. 341, a joint resolution in the House of Representatives which led to her promotion to commodore by special Presidential appointment. In 1985, the rank of commodore was renamed rear admiral, lower half. She retired (involuntarily) from the Navy on August 14, 1986. At a celebration held in Boston on the USS Constitution to celebrate her retirement, Hopper was awarded the Defense Distinguished Service Medal, the highest non-combat award possible by the Department of Defense. At the time of her retirement, she was the oldest commissioned officer in the United States Navy (79 years, eight months and five days), and aboard the oldest commissioned ship in the United States Navy (188 years, nine months and 23 days).

She was then hired as a senior consultant to Digital Equipment Corporation, a position she retained until her death in 1992, aged 85.

Her primary activity in this capacity was as a goodwill ambassador, lecturing widely on the early days of computers, her career, and on efforts that computer vendors could take to make life easier for their users. She visited a large fraction of Digital's engineering facilities, where she generally received a standing ovation at the conclusion of her remarks. During many of her lectures, she illustrated a nanosecond using salvaged obsolete Bell System 25 pair telephone cable, cut it to 11.8 inch (30 cm) lengths, the distance that light travels in one nanosecond, and handed out the individual wires to her listeners. Although no longer a serving officer, she always wore her Navy full dress uniform to these lectures.

"The most important thing I’ve accomplished, other than building the compiler, is training young people. They come to me, you know, and say, “Do you think we can do this?” I say, “Try it.” And I back ‘em up. They need that. I keep track of them as they get older and I stir ‘em up at intervals so they don’t forget to take chances."

She was laid to rest with full military honors in Arlington National Cemetery.
