Hans Rosenfeldt (born Hans Petersson on 13 July 1964) is a Swedish screenwriter, radio presenter, novelist and actor. He co-created the Swedish series De drabbade (2003) and Oskyldigt dömd (2008–09), and created the Scandinavian series The Bridge (2011–present).
Hans Petersson was born in 1964 in Borås, Västergötland. He grew particularly tall during puberty and was treated with growth hormone at fourteen years old to limit his growth. He reached his full height of 2.06 metres (6.8 ft) at fourteen. He considered a career as a basketball player, and briefly worked as a sea lion trainer at Borås djurpark. He also had jobs as a chauffeur and a teacher before deciding to become an actor. He took on the surname Rosenfeldt – his mother's maiden name – during school, replacing his birth name.
Rosenfeldt began acting in the late 1980s. In addition to small television roles, he acted with the Gothenburg National Theatre for five years, eventually that he did not enjoy acting. Instead, he applied for a job at the radio program Glädjetåget and soon began writing for television, including the soap operas Rederiet and Tre kronor, in the 1990s.
As a radio personality, he has been a recurring panel member on Sveriges Radio P1's På Minuten for over a decade. He has also worked as a television presenter, hosting the game show Parlamentet from 2000 to 2003. In 2007, he co-wrote Sveriges Television's Christmas calendar, En riktig jul. He served briefly as an entertainment management at Sveriges Television, but did not feel suited to the role. Rosenfeldt hosted Sveriges Radio's winter program in 2009 and 2011; the story of the 2009 program was inspired by his mother's experience with dementia.
