Keith Wilson helped design and manufacture the famed SM57 and SM58 microphones for Shure back in the early 1960s. As an engineer, Keith later came up with the idea of creating a system for vocalists, with mixer, amplifier and a microphone that could cover the range of the human voice. The system soon became one of the company’s most successful. While working at Shure, Keith also began designing sound systems for auditoriums and large performance halls. After leaving Shure in the early 1970s he formed his own sound design company, which is currently being run by his daughter.
