We were informed by Mark Diederichs, on behalf of Evert Hoek’s family, that Dr. Evert Hoek passed away peacefully on the morning of Saturday, 6 July 2024.

Evert Hoek was much loved by his family and admired and valued as a friend, teacher and colleague. A true giant in rock mechanics, rock engineering and in life, we will miss him greatly. In the ISRM we don't forget his contributions, namely the memorable 1st ISRM Leopold Müller Lecture in 1991 "When is Design in Rock Engineering Acceptable". Our thoughts are with his family and friends.
