Simon Helberg was born and raised in Los Angeles but despite this, and the fact that his father is the actor Sandy Helberg and his mother the casting director Harriet B. Helberg, his main interest as a young boy was karate. In his teens, though, he discovered acting and went on to study at New York University's Tisch School of the Arts where he trained at the Atlantic Theater Company. He started acting in 1999, taking guest roles and small parts, establishing himself as a character performer and able sketch comedian. Solid TV work followed throughout the 2000s until he was cast as Howard Wolowitz in the hit TV comedy The Big Bang Theory (2007) for which he remains best known.
