  In celebration of Professor Ron Doney's 80th birthday, we provide a summary
of his academic career and contributions to probability theory, as one of the
UK's leading probabilists for over 50 years. A version of this note also serves
as an introductory article to the volume in honor of Ron Doney [Birkh\"auser,
2021], which includes an additional 17 research papers produced by Ron's
colleagues and friends.
