Heinz studied modern languages at Bonn and Toulouse and after completing his PhD he decided to become a librarian. He has spent most of his professional life in academic libraries.
Through his work he came in contact with Cambridge University and was elected to a visiting fellowship at Sidney Sussex College in 1997. He has extensive experience in both alumni relations and development as a volunteer.
Heinz's link with St John’s comes through his son, Matthias, who studied for a Master of Science degree in psychology at Durham. Heinz has since contributed to College by teaching, tutoring and consulting in the fields of alumni relations and fundraising.
