On the eve of the United States entering World War II, the U.S. was woefully unprepared—both militarily and in the realm of intelligence. The United States did not have a professional intelligence service, but that was about to change.

President Franklin D. Roosevelt recognized the need for a professional global intelligence service. He was worried about the state of the United States intelligence services, which operated strictly on an ad hoc basis, without any overall direction or leadership. All counterespionage activities took place under the auspices of the FBI and its director, J.Edgar Hoover, who tried to quash any talk of a military intelligence service.

FDR turned to a man whom he greatly respected but who was at the opposite end of the political spectrum. William Donovan was a war hero in World War I with the “Fighting 69th,” part of the Rainbow Division, formerly known as the “Irish Brigade” that rose to fame during the Civil War. Donovan was awarded the Medal of Honor for his exploits. He also joined General Pershing’s punitive expedition in Mexico to find Pancho Villa before the U.S. entered the war.

After the war, Donovan was, for a time, the assistant attorney general. During that time he earned the enmity of Director Hoover, something that would rear its head again and again. Donovan also developed contacts all over the world as part of a network of businessmen. They proved much more adept at tracking and collecting intelligence than any government agency.

Donovan was recognized as an expert in such matters and FDR, despite their differences, recognized this. On July 11, 1941, FDR appointed Donovan the chief of a new organization known as the office of the Coordinator of Information (COI), which proved to be a harbinger of things to come, paving the way for the OSS (Office of Strategic Services) and later, the CIA. FDR ordered Donovan to draft a plan for the United States to create an agency similar to the British MI-6. Donovan was uniquely qualified to accomplish this.

Donovan quickly began drawing fire from the FBI and every other government agency; they viewed the COI as encroaching on their turf. Donovan set up shop in the Rockefeller Center in New York City. He hired Allen Dulles to head operations. Not coincidentally, the British MI-6 offices could be found one floor below. The British provided extraordinary help in developing this fledgling agency. Donovan had close contacts with the British intelligence agencies as well as with Winston Churchill and King George VI, and it showed.

Everything changed on December 7, 1941, when the Japanese bombed Pearl Harbor. The U.S. was now at war and things were about to change in a big way. Donovan urged FDR not to intern Japanese-Americans, believing that the government was addressing a problem that didn’t exist.

Donovan immediately set up espionage and sabotage programs, created a massive amount of front companies for clandestine operations overseas, and set about recruiting what he later termed his “glorious amateurs”—among them several females who, at the time, were considered “unsuitable for espionage.”
