Actor David Tennant was born David John McDonald on April 18, 1971 in Bathgate, Scotland. He was the youngest of three children. His father was a Presbyterian minister. At the age of 3, he decided he wanted to be an actor, reportedly after watching Doctor Who. In grammar school, he wrote an essay about wanting to be Doctor Who. David attended the Royal Scottish Academy of Music and Drama in Glasgow. He changed his professional name because there already was an actor called David McDonald. He got the name Tennant from Neil Tennant of the English group The Pet Shop Boys.

David Tennant is best-known to most for his role as the 10th Doctor Who. However, he had a long and varied career before playing the Doctor. One of his first theatrical roles was in the Resistible Rise of Arturo Ui in 1991; he went on to appear in many more plays. He also began appearing on British television beginning in 1993; his first appearance was a role on the TV series Rob C. Nesbitt. In 2004, he appeared in the hugely successful television series Blackpool. He also had great success with his role of Casanova in 2005. In 1996, David joined the Royal Shakespeare Company and appeared in several productions; mainly playing comic characters.

His first movie was Jude in 1996; he had a small unnamed part as a drunken undergraduate. He did several more films from 1997 to 2003. He also played Barty Crouch Jr. in Harry Potter and the Goblet of Fire in 2005. In 2005, he was also cast as Doctor Who (a role he played until 2009). He quickly became one of the most popular Doctor's. It was announced in 2007 that David Tennant was leaving the role of Doctor Who behind him. In late 2008, he played the roles of Hamlet in Hamlet and Berowne in Love's Labour's Lost on stage with the Royal Shakespeare Company to rave reviews, but had to pull out for several weeks due to a slipped disk which required surgery. He appeared in several Doctor Who specials during the 2009 season.

In the course of his career, David Tennant has received numerous awards and nominations; I'm sure there are many more in his future. He took the role of Doctor Who and quickly made it his own. I look forward to what will come next in his career.
