Dennis Butler Fry

Dennis Butler Fry (3 November 1907 – 21 March 1983) was a British linguist and Professor of Experimental Phonetics at University College London. Through experiments he conducted in the 1950s and 1960s, Fry demonstrated that lexical stress correlated with loudness, pitch, and duration of the affected vowel.
