Daniel Crouch has worked as a bookseller since the age of sixteen; first at Sanders of Oxford on weekends and holidays whilst at school and university, before starting full-time in 1997 and becoming general manager in 1998. Subsequent to this, he left to work as a business developer in the book department at Bonham's auction house in 1999. In 2002 he was invited to set up a map and atlas department at Bernard Shapero Rare Books in London.
In 2010, with the support of a group of his close colleagues and customers, Daniel together with Nick Trimming started Daniel Crouch Rare Books. Daniel still lives in Oxford with his wife, Jen, and two daughters.
