Finn was born on 22 April 1946 in
Brisbane. His father died when Finn was a child. He completed a
Bachelor of Arts degree at the
University of Queensland, majoring in literature. Although his father and stepfather were both lawyers, Finn was never pressured into following them into the legal profession; in an interview in 2010, he stated: "I did law by default, probably a lack of imagination". He later completed a
PhD at
Gonville and Caius College, Cambridge, England, Finn won the
Yorke Prize in his final year, and this treatise formed the basis of Finn's 1977 book
Fiduciary Obligations. ==Academic career==
