Bjørn Rasmussen was born in 1983 and grew up in a village near Lemvig. He graduated from Danish Playwright School in Aarhus in 2007. He also attended the Danish Writers’ School in Copenhagen in 2009 - 2011.
His theatre debut happened in 2004 at Theater Katapult in Aarhus with the performance of his play Mosquito marches in a sweet blood. His first novel The skin is the elastic envelope that surrounds the entire body was published in 2011. The novel is a beginning of author's characteristic focus on the study regarding the human body, sexuality and identity. It's substance is also eminently autobiographical which is one of the main typical features of Rasmussen's work, even though he never gets extremely private. In 2013, he published a poetic novel Pynt, and in 2015 he released his first poem collection Ming.
All publications have been profoundly praised. The debut received six stars in Jyllands-Posten, five in Politiken and Rasmussen also obtained Montanas Literature Prize in 2011. In 2013, he received the State Art Foundation's work placement and KulturBornholm Literature Prize in 2014.
