Definition
William Shepherd is an American former NASA astronaut, retired United States Navy captain, and aerospace engineer, noted for commanding the International Space Station (ISS) Expedition 6 and for participating in multiple Space Shuttle missions.
Overview
Born William McAlpine Shepherd on July 19 1949 in Seattle, Washington, he earned a Bachelor of Science in aeronautical engineering from the United States Naval Academy (1971) and a Master of Science in aeronautical engineering from the U.S. Naval Postgraduate School (1974). After serving as a naval aviator and test pilot, Shepherd was selected by NASA in the 1978 astronaut group, the first class of mission specialists.
During his NASA career, Shepherd flew on five Space Shuttle missions: STS‑27 (1988), STS‑33 (1989), STS‑44 (1991), STS‑61 (1993), and STS‑76 (1996). He later served as commander of the six‑month ISS Expedition 6 (December 2002–June 2003), becoming the first astronaut to command a long‑duration stay on the station. Following his spaceflight service, he held senior leadership roles, including chief of the Astronaut Office and director of flight crew operations. Shepherd retired from NASA and the U.S. Navy in 2005.
Etymology/Origin
The given name “William” is of Old Germanic origin, derived from Wilhelm (“wil” meaning “will, desire” and “helm” meaning “helmet, protection”). The surname “Shepherd” originates from the Middle English occupational term for a person who tended sheep, itself derived from the Old English sceaphierde (“sheep” + “herder”). The combination reflects a typical Anglo‑American naming convention.
