Cornelis Vreeswijk was a Dutch-born Swedish singer-songwriter and poet.
He emigrated to Sweden with his parents in 1949 at the age of twelve. He was educated as a social worker and hoped to become a journalist, but became increasingly involved in music, performing at events for students with idiosyncratic humor and social engagement. Vreeswijk is considered one of the most influential and successful troubadours in Sweden. In 2010, the Swedish drama film Cornelis was made about his life, directed by Amir Chamdin.
