Henry Franklin Winkler was born on October 30, 1945, in Manhattan, New York. His parents, Ilse Anna Maria (Hadra) and Harry Irving Winkler, were German Jewish immigrants who escaped the Holocaust by moving to the United States in 1939. His father was the president of an international lumber company while his mother worked alongside his father. Winkler is a cousin of Richard Belzer.
Growing up, Winkler struggled with academics due to undiagnosed dyslexia, which led to low self-esteem. He had other plans as he saw roles on stage as the key to his happiness. Winkler's acting debut came in the eighth grade when he played the role of Billy Budd in the school play of the same name. He received a Bachelor's degree from Emerson College in 1967 and a Master of Fine Arts degree from the Yale School of Drama in 1970.
After college, Winkler began his career by appearing in 30 commercials. His first major film role was in The Lords of Flatbush (1974) in which he played a member of a Brooklyn gang. He was cast on a new ABC series, Happy Days (1974),as high school dropout and greaser Arthur "Fonzie" Fonzarelli. The character became extremely popular with viewers, and the show's producers decided to give Fonzie a more prominent role in the series.
Following Happy Days, Winkler's popularity soared, and Fonzie became a 1970s icon and the epitome of cool. He remained on the series until its cancellation in 1984. In the mid-1980s, Winkler decided to change his focus toward producing and directing. He produced and directed several television shows and movies, most notably MacGyver (1985) and Sabrina the Teenage Witch (1996).
In the mid-1990s and early 2000s, Winkler re-established himself with a younger generation of moviegoers and TV viewers, appearing in the popular films, Scream (1996) and The Waterboy (1998) and on shows such as The Practice (1997) and Arrested Development (2003).
In 2018, after over 45 years in the entertainment industry, Winkler won his first-ever Prime Time Emmy Award: Outstanding Supporting Actor in a Comedy Series for his role on the HBO series Barry (2018). In addition to his movie and film credits, Winkler is a well-accomplished author. Between 2003 and 2007, he co-authored 12 children's novels with Lin Oliver.
Winkler has been married since 1978 to Stacey Winkler (nee Weitzman) with whom he has three children. Together, they are actively involved with various children's charities. In 1990, they co-founded the Children's Action Network (CAN),which provides free immunization to over 200,000 children.
