John Burnside (inventor)
- For the Scottish writer (born 1955), see John Burnside.
John Lyon Burnside III (November 2, 1916 – September 14, 2008) was the inventor of the teleidoscope, the darkfield kaleidoscope and the Symmetricon. Because he rediscovered the math behind kaleidoscope optics, for decades, every maker of optically correct kaleidoscopes sold in the United States paid him royalties. Harry Hay was his life partner from 1962 until Hay's death in 2002. He was living in San Francisco, California, at the time of his death on September 14, 2008 from complications of brain cancer.

Gay rights activismEdit
Burnside and Hay formed a group in the early 1960s called the Circle of Loving Companions that promoted gay rights and gay love. In 1979 they were major planners of one of the first gay parades, a protest against exclusion of homosexuals from the military, held in Los Angeles. In 1967, they appeared as a gay couple on the Joe Pyne television show.
Burnside married Edith Sinclair in Los Angeles. The pair had no children. Burnside later met Harry Hay in 1962 at ONE Incorporated; the two fell in love and became life partners. Burnside died Sunday, September 14, 2008 at the age of 91.  His ashes, mingled with those of his partner Harry Hay, were scattered in Nomenus Faerie Sanctuary, Wolf Creek, Oregon.
