Benjamin Francis Laposky (1914–2000) was a mathematician, artist and draftsman in Cherokee, Iowa. He has been credited with making the first computer graphics, utilizing an oscilloscope as the creation medium for abstract art. In 1953 he released what he called "Oscillons" (or oscillogram designs) along with a corresponding thesis entitled "Electronic Abstractions" via a gallery exhibition of fifty pictures of the same name at Sanford Museum in Cherokee. Laposky is often credited as the pioneer for electronic art, more specifically in the analog vector medium.More about Laposky: Laposky’s Lights Make Visual Music
In 1950 Laposky used a cathode ray oscilloscope with sine wave generators and various other electrical and electronic circuits to create abstract art, so called by the artist, "electrical compositions". These electrical vibrations shown on the screen of the oscilloscope were then recorded using still photography. In later work he also incorporated motorized rotating filters of variable speed to color the patterns.
