Thomas Wilfred (June 18, 1889 in Naestved, Denmark – August 15, 1968 in Nyack, New York), born Richard Edgar Løvstrøm, was a visual artist, inventor, designer and musician.

Wilfred was not fond of the term "color organ", and coined the word "Clavilux" from Latin meaning "light played by key".

World War II found the Grand Central Palace theatre turned into an Army induction center, and Wilfred did his part for the Allies by serving as a translator.

In 2003, two of the original Clavilux (Models E & G) were rescued from an East Village eviction dumpster, and are now stored in Seattle, Washington awaiting restoration by the Epsteins.

In 1952, he was included in the influential Museum of Modern Art exhibition 15 Americans, alongside Abstract Expressionists such as Jackson Pollock, Willem de Kooning, and Mark Rothko.

Because of his influence on this generation of artists, Wilfred's final work "Lucatta, Opus 162" was included in the "Summer of Love" exhibition, which was hosted by the Whitney Museum in the spring of 2007.

In 2017, Yale University Art Gallery organized the first exhibition dedicated solely to Wilfred and his light compositions in more than forty years.
