Edwin Albert Link
American inventor and underwater diver (1904–1981)
Edwin Albert Link (July 26, 1904 – September 7, 1981) was an American inventor, entrepreneur and pioneer in aviation, underwater archaeology, and submersibles. He invented the flight simulator, which was called the "Blue Box" or "Link Trainer". It was commercialized in 1929, starting a now multibillion-dollar industry. In total, he obtained more than 27 patents for aeronautics, navigation and oceanographic equipment.
Early life
Edwin Link was born in Huntington, Indiana, in 1904, the son of Edwin A. Link Sr. and Katherine (Martin) Link. In 1910, he moved with his family to Binghamton, New York.

Aviator
He took his first flying lesson in 1920. In 1927, he obtained the first Cessna airplane ever delivered and eked out a living by barnstorming, charter flying and giving lessons.
As a young man, Edwin Link used apparatus from his father's automatic piano and organ factory (of the Link Piano and Organ Company) to produce an advertising airplane.

Why this record matters
The phrase “american inventor and underwater diver (1904–1981)” 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.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated May 22, 2026. The linked authority identifier is Q1294379. VIAF identifies the subject as 89152023. The Library of Congress control number is n84801414. 4 of 4 selected statements include explicit references; 1 carry qualifiers and 1 use preferred rank. The first chronological checks are 1904, 1981, 1929 and 1910.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. 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.
