Duane H. Cooper
American physicist (1923–1995)
Duane H. Cooper (August 21, 1923 in Gibson City, Illinois – April 4, 1995) was a physicist, who made early investigations regarding
the intricate geometry of the phonograph stylus-groove interface.
He earned a Bachelor of Science and Ph.D. degree with honors in physics in 1950 and 1955 from the California Institute of Technology.
In 1954, Cooper joined the Coordinated Sciences Laboratory at the University of Illinois, where
he became a research professor. He developed a unified treatment of phonograph tracking and tracing distortion by utilizing a skew transformation. In the late 1960s and early 70s, Cooper contributed significantly to the theory of surround sound
multi-channel stereo.
Cooper served as president of the Audio Engineering Society (AES) from 1975-1976. He was named an AES Fellow in 1966, and received the AES Silver and Gold Medals.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Duane H. Cooper”, the useful work is to connect “american physicist (1923–1995)” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 1, 2026. The linked authority identifier is Q5310336. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1923, 1995, 1950 and 1955.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
