In his own words, Bob would say that he "Stood on the Shoulders of Giants."
Audio synthesis had been experimented with for quite some time, but in the 1950's and 60's the electronic & musical landscape was in the process of dramatic change.
Being a gifted engineer and inventor and having a talent for music, he saw the possibility of melding science with art.
With the development of the Moog Synthesizer a large stone was cast into the sea of music. The waves that Bob created continue to lap on the shore of musical creativity, and likely will continue to affect all synthesis long into the future.
Bob has become one of those very Giants upon whose shoulders others can now stand.
