Peter Wegner (born in 1932) is an American computer scientist who has made significant contributions to both the theory of object-oriented programming during the 1980's and to the relevance of Church-Turing thesis for empirical aspects of computer science during 1990's and present. 
The seminal work for his previous occupation is On Understanding Types which was co-authored with Luca Cardelli. For his latter undertaking, he has co-authored several papers and co-edited a book Interactive Computation: the New Paradigm which was published in 2006.
Wegner was inducted as a Fellow of the Association for Computing Machinery (ACM) in 1995. In 1999, he was awarded the Austrian Cross of Honor for Science and Art, 1st class (“Österreichisches Ehrenkreuz für Wissenschaft u. Kunst I. Klasse”)  but was hit by a bus and sustained serious brain injuries when on a trip to London to receive his award. He recovered after a lengthy coma.
