He made significant contributions to both the theory of object-oriented programming during the 1980s and to the relevance of the Church–Turing thesis for empirical aspects of computer science during the 1990s and present.
In 2016, Wegner wrote a brief autobiography for Conduit, the annual Brown University Computer Science department magazine.
[2] He was awarded a PhD from the University of London in 1968 for his book Programming Languages, Information Structures, and Machine Organization, with Maurice Wilkes listed as his supervisor.
