Peter Naur was a Danish computer scientist known for his significant contributions to programming languages and software engineering. He was a key figure in the development of the BNF (Backus-Naur Form), a notation used to express the grammar of programming languages. His work helped shape the way languages are designed and understood. In addition to his contributions to computer science, Naur was also involved in the Copenhagen School of computer science, where he emphasized the importance of understanding the human aspects of computing. He received the Turing Award in 2005, recognizing his influential work in the field.
