Following World War II, Friedman remained in government signals intelligence. These included messages between Tokyo and Japanese embassies around the world, which provided valuable data for the conduct of the war. However, because of the large volume of intelligence being received by the staff of Magic, they were unable to give adequate warnings about the proposed attack at Pearl Harbor. His services were often in demand by other federal agencies, and he became a leader in many international communications activities. By 1917, because of World War I, various federal offices were calling upon the Friedmans for deciphering; the couple set up a school in cryptology for military personnel at Riverbank. He is considered one of the world’s greatest cryptologists, who helped decipher enemy codes from World War I to World War II. A primary function of the unit was "black chamber" work (covert interception and analysis of other governments' messages). Accordingly, this work gives a fair and scientific hearing to those anti-Stratfordians whose theories were often dismissed completely.

He was demobilized in April 1919 and returned to Riverbank. In addition to setting up a global network of radio-intercept stations, Friedman's group also developed new codes and ciphers and established the Signal Intelligence School. With increases in the number of people working at Magic they were able to discover the attack plan at the Battle of Midway. After graduating from Pittsburgh's Central High School in 1909, Friedman entered Michigan Agricultural College.After one year he transferred to Cornell University, earning B. S. and M.
