Michael J. Fox

Michael J. Fox is the boyish actor who became a public advocate for Parkinson's Disease research after developing the disease himself. As an actor, Fox's specialty was an earnest and ambitious charm, a trait he put to good use while playing the buttoned-down youngster Alex P. Keaton in the 1980s comedy series Family Ties. The show was a springboard for Fox, who hit big screen stardom as time-traveling teen Marty McFly in the hugely successful Back To The Future film series: Part I (1985), Part II (1989) and Part III (1990). After several feature films, including a few turns at drama (1987's Light of Day and 1989's Casualties of War), Fox returned to television in the political sitcom Spin City (1996-2001). Fox shocked his fans in 1998 when he announced he was suffering from Parkinson's Disease. In the years since, he has been the public face for the Michael J. Fox Foundation for Parkinson's research and been on screen occasionally, notably a guest spot in the Denis Leary television drama Rescue Me in 2009. Fox's 2002 memoir was titled Lucky Man.
