Brinch Hansen is one of the pioneers of concurrent programming and operating systems (kernels). He coined the Danish word for computer: Datamat (English: datamaton).

In the 1960s, Brinch Hansen worked at the Danish computer company Regnecentralen, first in the compiler group headed by Peter Naur and Jørn Jensen, and, later, as the chief architect of the RC 4000 minicomputer and its renowned operating system kernel (RC 4000 Multiprogramming System). In 1972, he wrote the first comprehensive textbook on Operating System Principles. The 1960s decade refers to the years from January 1, 1960 to December 31, 1969, inclusive. ...

Since 1970 his research in computer science has focused on concurrent programming: Inspired by Ole-Johan Dahl and Kristen Nygaard's programming language Simula 67, he invented the monitor concept in 1972. In the United States, he also developed the first concurrent programming language, Concurrent Pascal, in 1975. In 1977, he wrote the first book on Concurrent Programming: The Architecture of Concurrent Programs. Professor emeritus Ole-Johan Dahl (October 12, 1931 – June 29, 2002) was a Norwegian computer scientist and is considered to be one of the fathers of Simula and object-oriented programming along with Kristen Nygaard. ...

Simula is a programming language developed in the 1960s at the Norwegian Computing Centre in Oslo, primarily by Ole-Johan Dahl and Kristen Nygaard. ... A monitor is an approach to synchronizing two or more computer tasks that use a shared resource, usually a hardware device or a set of variables. ... Concurrent Pascal was designed by Per Brinch Hansen for writing concurrent programs such as operating systems and real-time monitoring systems on shared-memory computers. ...

More recently, Brinch Hansen has documented the historical development of these fundamental areas of computer science.

He was as of 2004 a professor at Syracuse University in New York State.
