Early-life: Born James Joseph Parsons on March 24, 1973 in Houston, Texas.

He was accepted onto a two-year course in classical theatre at the University of San Diego in 1999 and, after graduating in 2001, he moved to New York.

Career: Early in his career, Parsons worked on Off-Broadway productions and appeared on TV several times. He had a recurring role on Judging Amy, appeared on the TV series Ed and had minor roles in such films as Garden State (2004) and School for Scoundrels (2006). His big break came when he landed the role of Sheldon Cooper in The Big Bang Theory, a role that earned him four Primetime Emmy Awards for Outstanding Lead Actor in a Comedy Series and a Golden Globe for Best Performance by an Actor in a Television Series - Comedy or Musical. He went on to appear in the films The Big Year (2011), The Muppets (2011), Home (2015) and Hidden Figures (2016).
