Early life and education
Byron Willis McCandless was born on June 8, 1937, in Boston, Massachusetts. A third-generation U.S. Navy officer, McCandless was the son of Bruce McCandless and grandson of Willis W. Bradley, both Medal of Honor recipients. His mother changed his name on June 6, 1938, to Bruce McCandless II. He graduated from Woodrow Wilson Senior High School, Long Beach, California, in 1954.
In 1958, he received a Bachelor of Science from the United States Naval Academy, graduating second, behind future National Security Advisor John Poindexter, in a class of 899 that also included John McCain. During his professional career, he also received a Master of Science in electrical engineering from Stanford University in 1965 and a Master of Business Administration from the University of Houston–Clear Lake in 1987.
United States Navy
Following his commissioning, McCandless received flight training from the Naval Air Training Command at Naval Air Station Pensacola, Florida, and Naval Air Station Kingsville, Texas.
In March 1960, he was designated a United States Naval Aviator and proceeded to Naval Air Station Key West for weapons system and carrier landing training in the Douglas F4D-1 Skyray.
Between December 1960 and February 1964, he was assigned to Fighter Squadron 102 (VF-102), flying the Skyray and the McDonnell Douglas F-4B Phantom II. He saw duty aboard USS Forrestal and USS Enterprise, including the latter's participation in the Cuban Missile Crisis.

Why this record matters
The phrase “american astronaut (1937–2017)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 2, 2026. The linked authority identifier is Q433608. VIAF identifies the subject as 300814769. The Library of Congress control number is no2021105557. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1937, 2017, 1984 and 1938.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
