Tregoweth Edmond "Treg" Brown (November 4, 1899 in Gilbert, Minnesota, USA – April 28, 1984) was a motion picture sound editor who was responsible for the sound effects in Warner Bros.' Looney Tunes and Merrie Melodies cartoons from 1936 up until 1965. Before that, he worked with Cecil B. DeMille. Adding to this, he also gave Warner voice actor Mel Blanc his big break. He also won the 1965 Academy Award for Sound Effects for his work on the film The Great Race. After Warner Bros. Animation closed in 1963, Treg worked for DePatie-Freleng Enterprises for a few years. In addition to creating his own sound effects, Treg Brown would also often draw upon Warner Bros. Pictures's sound effects library used in their live-action films for certain sounds (such as gunshots, bodyfalls, automobiles, etc.)
In the Warner Bros. cartoon One Froggy Evening (1955), the skyscraper into which Michigan J. Frog is entombed is named the "Tregoweth Brown Building".
Many of his sound effects he created (not all) are available on the Warner Bros. Sound Effects Library, along with some appearing on the Hanna-Barbera Sound Effects Library, The International Sound Effects Library, and more.
