Thomas Wilfred (June 18, 1889 in Naestved, Denmark - June 10, 1968 in Nyack, New York) born Richard Edgar Løvstrøm, was a musician and inventor. He is best known for his visual music 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".
