Bjarne Stroustrup (born 30 December 1950) is a Danish computer scientist, most notable for the creation and development of the C++ programming language. He is a visiting professor at Columbia University, and works at Morgan Stanley as a Managing Director in New York.

He attended Aarhus University 1969–1975 and graduated with a master's degree in mathematics and computer science. His interests focused on microprogramming and machine architecture. He learned the fundamentals of object-oriented programming from its inventor, Kristen Nygaard, who frequently visited Aarhus.

Stroustrup is best known for his work on C++. In 1979, he began developing C++ (initially called "C with Classes"). In his own words, he "invented C++, wrote its early definitions, and produced its first implementation [...] chose and formulated the design criteria for C++, designed all its major facilities, and was responsible for the processing of extension proposals in the C++ standards committee." C++ was made generally available in 1985.

For non-commercial use, the source code of the compiler and the foundation libraries was the cost of shipping (US$75); this was before everyone had Internet access. Stroustrup also published a textbook for the language in 1985, The C++ Programming Language.
