Mel Tanner (September 26, 1925 - October 21, 1993) was an American light sculptor, painter, installation artist, and videographer. His wife, Dorothy Tanner (January 30, 1923 - July 23, 2020), was an American light sculptor, installation artist, musician, videographer, and spoken word artist based in Denver, Colorado. The couple worked very closely for over 40 years. Their main project was the creation of Lumonics that consists of their light sculptures, live projection, video, electronics, and music as a total art installation. Author and art historian, Michael Betancourt, described this visual music performance work as a Gesamtkunstwerk in his book, The Lumonics Theater: The Art of Mel & Dorothy Tanner, published in 2004.
