Steven William Moffat, OBE (/ˌstiːvən ˈmɒfət/, born 18 November 1961) is a Scottish television writer and producer, known for his work as showrunner, writer and producer of the British television series Doctor Who and Sherlock.
Moffat's first television work was the teen drama series Press Gang. His first sitcom, Joking Apart, was inspired by the breakdown of his first marriage; conversely, his later sitcom Coupling was based upon the development of his relationship with television producer Sue Vertue. In between the two relationship-centred shows, he wrote Chalk, a sitcom set in a comprehensive school inspired by his own experience as an English teacher.
A lifelong fan of Doctor Who, Moffat's first work on the series was the script of the parody episode The Curse of Fatal Death in 1999. He then wrote six episodes of the revived series which began in 2005 ("The Empty Child", "The Doctor Dances", "The Girl in the Fireplace", "Blink", "Silence in the Library", and "Forest of the Dead"). In 2010 he replaced Russell T Davies as showrunner, lead writer and executive producer. The same year, he created Sherlock along with Mark Gatiss. In January 2016, it was announced that Moffat would step down from being showrunner of Doctor Who after the spring 2017 season finale, and that Broadchurch creator Chris Chibnall would take over. He also co-wrote Steven Spielberg's The Adventures of Tintin: The Secret of the Unicorn in 2011.
Moffat has won several awards, mainly for Doctor Who and Sherlock, including an Emmy Award, five BAFTA Awards and four Hugo Awards.
