In 1919 he founded what was then known as
American Asiatic Underwriters (later American International Underwriters) in
Shanghai,
China, a global insurance and investment organization. After Japan invaded China in 1939, he moved his operation to New York to work for the
Office of Strategic Services (OSS), the precursor to the
CIA. in 1943 he established the
OSS insurance intelligence unit with
William "Wild Bill" Donovan and served as the chief operative behind former
U.S. Army Air Force officer
Claire L. Chennault. ''’, was founded to help the Chinese in the fight against the Japanese occupiers Chennault is best known for coordinating the OSS-bankrolled
American Volunteer Group (better known as the "
Flying Tigers") to bring the fight to the Japanese without a
declaration of war and return Generalissimo
Chiang Kai-shek to dominance in China. Starr and the OSS later backed Chiang over Communist leader
Mao Zedong. In 2000, war correspondent and author
Mark Fritz wrote in the article entitled
The Secret (Insurance) Agent Men for the
Los Angeles Times: They knew which factories to burn, which bridges to blow up, which cargo ships could be sunk in good conscience. They had pothole counts for roads used for invasion and head counts for city blocks marked for incineration. They weren't just secret agents. They were secret insurance agents. These undercover underwriters gave their World War II spymasters access to a global industry that both bankrolled and, ultimately, helped bring down
Adolf Hitler's Third Reich. After World War II, Starr hired O.S.S. captain
Duncan Lee, a lawyer, who became the long-term general counsel of AIG. AIG left China in early 1949, as Mao led the advance of the Communist
People's Liberation Army on Shanghai, and Starr moved the company headquarters to its current home in New York City. AIG was the world's largest insurance company, and as of 2021 remains unchallenged in that respect. ==Legacy==
