Thomas Wilfred (June 18, 1889 in Naestved, Denmark - August 15, 1968 in Nyack, New York), born Richard Edgar Løvstrøm, was a musician and inventor. He is best known for his light art, which he named lumia, and his designs for color organs called Clavilux. Wilfred was not fond of the term "color organ", and coined the word "Clavilux" from Latin meaning "light played by key". His innovative, kinetic works prefigured the advent of light art in America, and influenced subsequent generations of visual artists.
