Joseph Schillinger (1895–1943) was born in Kharkov (modern-day Kharkiv, Ukraine) and immigrated to America where he became a citizen in 1936. He was a pianist, composer, music theorist, mathematician, and art professor at Columbia University. Mathematics and geometry shaped all of his teachings. Cubist three-dimensional geometric displays with colorful visuals enabled his students to grasp music in a whole new way. He showed them what music looked like in geometric forms.
