Theodore Keep was a co-founder of Liberty Records. In his role as chief of engineering at the label and afterward, Keep introduced a number of innovations to commercial sound recording.
During the 1950s, Keep provided the synchronization process that allowed combining of the speed-doubled voice technique with full orchestration on "Witch Doctor." As a result, Keep received Grammy Awards in 1959 and 1960.
One of the major acts who recorded on Liberty Records was Alvin and the Chipmunks, actually Ross Bagdasarian, Sr., who recorded as David Seville. Seville named The Chipmunks (Alvin, Simon, and Theodore) after Liberty Records executives Alvin Bennett, Simon Waronker, and Theodore Keep, respectively.
