Background and career

Beck was born in Chicago, Illinois but he grew up in Evanston and Joliet on his father's ranch, with the goal of becoming a veterinarian. His goals changed at the age of sixteen after performing in a play in high school to overcome shyness. Three years later, Beck relocated to California and had jobs in television commercials. In 1963–1964, Beck attended Joliet Junior College but quit to begin acting in plays in other cities.
