Dave Rossum (David P. Rossum) is an American electronics engineer and co-founder of the synthesizer company E-mu Systems.

Education and early career
Rossum attended the California Institute of Technology, earning a Bachelor of Science Biology in 1970.

Later that year while pursuing graduate studies at the University of California at Santa Cruz, Rossum’s advisor, Harry Holier, invited him to join him in the music department where students were unpacking the university’s new Moog Model 12 modular synthesizer. Rossum discovered an affinity for synthesis and invited Caltech friends who aspired to build their own synthesizer to come see the Model 12. Over the next year Rossum and his Caltech friends built two prototype synthesizers which they named the Black Maria and Royal Hearn. A company name was needed for invoices related to the parts purchased for these synthesizers, and Rossum came up with the name Eµ Systems.

E-mu Systems
1972 co-founded E-mu Systems with high school friend Scott Wedge.
