Age, Early Life, and Education Background

William Theodore Katt was actually born Herman August Wilhelm Katt under the Aquarius zodiac sign on 16 February 1951, in Los Angeles, California, so is 72 years old as of 2023. He is the son of Barbara Hale and Bill Williams, aka William Herman Katt. Both of Katt’s parents were famous actors; his mother is probably best remembered for portraying Della Street in the drama series “Perry Mason,” and her outstanding performance brought her an Emmy Award, whereas his father was perhaps best known for starring in the TV series “The Adventures of Kit Carson.” Katt appeared alongside his mother in numerous Perry Madison made-for-TV films. He has two sisters named Jody Katt and Juanita Katt, and they spent their childhood in the San Fernando Valley and often accompanied their parents to the sets of various projects they worked on. As a result, William grew up very interested in acting and music.

Katt has portrayed numerous characters while appearing in over 100 projects since he began his acting career. He previously stated, ‘When I play a good guy, I try to explore them and figure out what shapes them and makes them interesting. When I’m playing a bad guy, I try to explore everything that makes them good. No one ever really thinks that they’re a bad guy.’ He began his acting career performing in summer stock theater, and later in minor TV roles. When he was 25 years old, Katt became the mentee of the Emmy Award-winning and three Academy Award-nominated American actress, Piper Laurie.
