American former child actor and singer who first gained fame as a teen idol in the late 1970s. At the beginning of his career his popularity quickly grew causing networks like CBS to create and implement multiple television series specifically for his involvement and leading roles. After making a record number of appearances on top talk shows he was viewed by many as “the face you see everywhere.”
In 1978, McNichol recorded an album with his sister, Kristy, also a former actress, and the two went on to host a youth-oriented variety show for ABC. McNichol subsequently had lead roles in Smokey Bites the Dust (1981), and opposite Susan Tyrrell in the horror film Butcher, Baker, Nightmare Maker (1981). After retiring from acting in the 1990s, McNichol relocated with his family to Colorado, and has been active in environmentalist causes, and working as a real estate investor and home renovator.
McNichol married his wife, Renée, in 1997. They had a son, Nash, in late 1997, and a daughter, Ellis, in late 1998. In 2010, he discovered he had a third child, daughter Kellee Maize (born 1980), a rap artist, songwriter, and entrepreneur from Pittsburgh, who had been raised by adoptive parents in Pennsylvania. The two subsequently began a relationship which was profiled in 2014 by Oprah Winfrey.
