Ivan Alexandrovich Vishnegradsky (1903–1979) was a prominent Russian composer and pioneer in the field of electronic music. His work is often associated with avant-garde and experimental genres, reflecting a deep interest in new sonic possibilities and the integration of technology in music.

Notable works include "Synthesis of the Arts," where he experimented with combining various art forms, and "Symphony for Electronic Instruments," which showcases his innovative approach to sound. His impact on music is significant, as he was one of the first composers to advocate for the use of electronic instruments in classical music, paving the way for future generations of composers in the electronic and avant-garde music scenes.

His legacy continues to inspire contemporary musicians and composers exploring the intersections of technology and art.
