imgNew York, NY (March 29, 2013)—The late Bob Moog, electronic music innovator and founder of Moog Music, has been named as one of this year's United States Patent and Trademark Office National Inventors Hall of Fame Inductees.

Moog will be recognized for his invention, Patent No. 3475623, more commonly known as the Moog Ladder Filter. Using the new properties provided by transistors, the Ladder Filter was the first voltage controlled filter. By using voltage control such as keyboards and envelopes to steer the harmonic content of music over time, the Ladder Filter allowed new ways of manipulating sound.

This invention laid the foundation for the electric pulse that beats through all forms of modern music. Bob brought to life basic concepts of dynamic filters used in the mix in every genre of recorded music today.  The Ladder Filter allows the organic movement of sound in such a way that people can not only hear its warmth, but also feel its sweep come to life. 

Patent No. 3475623 is best known for its use in the Minimoog Synthesizer and its effect can be heard on albums by artists like Michael Jackson, Kraftwerk, Parliament Funkadelic, Emerson Lake and Palmer, Dr. Dre, Diana Ross and Brian Eno.
