Rowan Sebastian Atkinson is an English comedian, actor and writer, famous for his title roles in the British television comedies Blackadder and Mr. Bean. Atkinson has been listed in The Observer as one of the 50 funniest acts in British comedy, and amongst the top 50 comedy acts ever in a 2005 poll of fellow comedians.

Rowan Sebastian Atkinson was born in Consett, County Durham in 1955. His parents were Eric Atkinson, a farmer and company director, and his wife Ella May (née Bambridge), who had married on 29 June 1945. His elder brother, Rodney Atkinson, is a eurosceptic economist who narrowly lost the United Kingdom Independence Party leadership election in 2000. Atkinson married Sunetra Sastry in 1990, having met her professionally on the set of Blackadder. They married quietly at the Russian Tea Room in New York City, U.S., with Stephen Fry acting as the best man. The couple have two children, Lily and Benjamin, and live in an Oxfordshire village.

He was educated at Durham Choristers School, followed by St Bees School, and studied electrical engineering at Newcastle University. He continued with an MSc at Queens College, Oxford, first achieving notice at the Edinburgh Fringe Festival in 1976. At Oxford, he also acted and performed early sketches for the Oxford University Dramatic Society (OUDS), the Oxford Revue and the Experimental Theatre Club (ETC), meeting writer Richard Curtis and composer Howard Goodall, with whom he would continue to collaborate during his career.

Atkinson toured with Angus Deayton as his straight man in an act that was eventually filmed for a television show. After the success of the show, he was offered his own television series by ITV in 1978. Atkinson turned it down in favour of Not the Nine O'Clock News, produced by his friend John Lloyd. He starred on the show along with Pamela Stephenson, Griff Rhys Jones and Mel Smith, and was one of the main sketch writers. The success of Not the Nine O'Clock News led to his starring in the medieval sitcom The Black Adder, which he also co-wrote with Richard Curtis, in 1983. Despite a mixed reception, a second series was written, this time by Curtis and Ben Elton, and first screened in 1985. Blackadder II followed the fortunes of one of the descendants of Atkinson's original character, this time in the Elizabethan era. The same pattern was repeated in two sequels Blackadder the Third (1987) (set in the Regency era), and Blackadder Goes Forth (1989) (set in the First World War). The Blackadder series went on to become one of the most successful BBC situation comedies ever.

Atkinson's other famous creation, the hapless Mr. Bean, first appeared on New Years Day in 1990 in a half-hour special for Thames Television. The character of Mr. Bean has been likened somewhat to a modern-day Charlie Chaplin. During this time, Atkinson appeared at the Just for Laughs comedy festival in Montreal in 1987 and 1989. Several sequels to Mr. Bean appeared on television in the 1990s, and it eventually made into a major motion picture in 1997. Entitled Bean, it was directed by Mel Smith, his former co-star from Not the Nine O'Clock News. A second movie was released in 2007 entitled Mr. Bean's Holiday.

Atkinson's film career began in 1983 with a supporting part in the James Bond movie Never Say Never Again and a leading role in Dead on Time with Nigel Hawthorne. He appeared in former Not the Nine O'Clock News co-star Mel Smith's directorial debut The Tall Guy in 1989.

Atkinson, with his turn as a verbally bumbling vicar, gained further recognition in the 1994 hit Four Weddings and a Funeral. That same year he featured in Walt Disney's The Lion King as Zazu the Hornbill. Atkinson continued to appear in supporting roles in successful comedies, including Rat Race (2001), Scooby-Doo (2002), and Love Actually (2003).

Atkinson was a stutterer as a child, a condition which sometimes returns when he is in stressful situations. In particular, the "B" sound posed a problem for him. He managed to overcome this through over-articulation; this evolved into one of his better-known trademark comic devices, such as his pronunciation of "Bob" in a Blackadder episode. Another trademark is his Received Pronunciation English accent. Because of this condition, Atkinson's style is often visually-based and rigorously rehearsed in part to ensure any stress-induced stutter is minimised. This visual style, which has been compared to Charlie Chaplin, sets Atkinson apart as most modern television and film comedies rely heavily on dialogue, and stand-up comedy is mostly based on monologues. This talent for visual comedy has led to Atkinson being called "the man with the rubber face".
