Robert A. Moog, whose self-named synthesizers turned electric currents into sound and opened the musical wave that became electronica, has died. He was 71.

Moog died Sunday at his home in Asheville, according to his company's Web site. He had suffered from an inoperable brain tumor, detected in April.

A childhood interest in the theremin, one of the first electronic musical instruments, would lead Moog to a create a career and business that tied the name Moog as tightly to synthesizers as the name Les Paul is to electric guitars.
