During World War II he worked for the Navy's codebreaking organization, OP-20-G. His career at NSA brought him to the very front rank of cryptologists. He was an early advocate of the use of computers for cryptologic work, and helped to cement a close working relationship with American industry. He helped to create and shape the NSA and was regarded both as a pioneer in the development of ever more powerful and sophisticated computers to break enemy codes and as a master administrator who pressed for establishing a combined military code-breaking operation and then virtually ran it under a series of military directors.
