Richard Fisher, managing director of academic publishing at Cambridge University Press, will step down from his role at the end of this year.
Fisher joined the publisher 30 years ago as a graduate trainee, working for many years as a commissioning editor in history and politics, before taking on a series of managerial roles and then being appointed m.d. of academic publishing in 2012. His departure is said to have been "a personal decision."
CUP chief executive Peter Phillips said: "Richard has overseen the biggest changes to the Academic group in a generation, with a new, dynamic and global team in place. Richard and I will be working with the team over the next few months to ensure that the growth of our academic business and products continues apace."
The recruitment process is now underway for a successor.
Separately, Fisher is currently away from the CUP office while he recovers from a broken leg, which put him in hospital for a 10-day period in February. It is expected to be several weeks before he is able to return to the office full-time.
