Hazeltine Corporation
American defense electronics company (1924–1986)

History
1924–1986
The company was founded in 1924 by investors to exploit the Neutrodyne patent of Dr. Louis Alan Hazeltine. Headquartered in Greenlawn, Long Island, New York, since 1955, it had facilities in several other locations in Long Island, including its Wheeler Laboratories facility in Smithtown, New York, manufacturing plants in Riverhead and Little Neck, NY, and a division in Braintree, Massachusetts. Hazeltine Corporation employed 2,600 people by 1981.
The company was created primarily to administer and license Hazeltine’s Neutrodyne patents to radio manufacturers. Through these licenses the Hazeltine Corporation received royalties on large numbers of broadcast receivers produced during the early 1920s, when the neutrodyne circuit became one of the dominant commercial receiver designs. The licensing program made the company one of the earliest examples of a technology firm organized around patent licensing rather than manufacturing; see Patents and licensing in early radio.

Why this record matters
The phrase “american defense electronics company (1924–1986)” 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.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Aug 19, 2026. The linked authority identifier is Q5688109. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1924, 1986, 1999 and 1955.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. 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.
