Tharon Myrene Musser (January 8, 1925 – April 19, 2009) was an American lighting designer who worked on more than 150 Broadway productions. She was termed the "Dean of American Lighting Designers" and is considered one of the pioneers in her field.
Musser was best known for her work on the musicals A Chorus Line and Dreamgirls. A Chorus Line was the first production of Broadway to use a fully computerized lighting console instead of manually operated "piano boards".
DMX512 is a standard for digital communication networks that are commonly used to control lighting and effects. It was originally intended as a standardized method for controlling stage lighting dimmers, which, prior to DMX512, had employed various incompatible proprietary protocols. It quickly became the primary method for linking controllers (such as a lighting console) to dimmers and special effects devices such as fog machines and intelligent lights.
DMX512 has also expanded to uses in non-theatrical interior and architectural lighting, at scales ranging from strings of Christmas lights to electronic billboards and stadium or arena concerts. It can now be used to control almost anything, reflecting its popularity in all types of venues.
