Solomon Adler (August 6, 1909 — August 4, 1994) was an economist in the U.S. Treasury Department who served as Treasury representative in China during World War II. He was identified by Whittaker Chambers and Elizabeth Bentley as a Sovietintelligence source and resigned from the Treasury Department in 1950. After several years teaching at Cambridge University in England, he returned to China, where he resided from the 1960s until his death, working as a translator and economic advisor. Beginning in the early 1960s, Adler was also affiliated with the Central External Liaison Department, an important Chinese Communist Party organ whose functions include foreign intelligence.
Solomon Adler was born on 6 August 1909 in Leeds, England. The Adler family was of Jewish ancestry and originally from Karelitz, Belarus, moving to Leeds in 1900. Solomon Adler was the fifth of ten children; the oldest was Saul Adler, who became a well-known Israeli parasitologist. Adler studied economics at Oxford and University College, London. He came to the United States in 1935 to do research. In 1936 he was hired at the Works Progress Administration's National Research Project, but soon moved to the Treasury Department's Division of Monetary Research and Statistics, where he worked with Harry Dexter White for the next several years.
Adler became a naturalized United States citizen in 1940. In 1941, he was posted to China, where he remained as Treasury representative until 1948. His reports from China to Treasury secretary Henry Morgenthau, Jr. during the war years were widely circulated and played an important role in shaping American wartime economic policy toward China.
In 1949, Adler became the subject of a Loyalty of Government Employees investigation. He resigned before the case was resolved and returned to Britain, where he taught for several years at Cambridge University. When his American passport expired, he was denaturalized and lost his American citizenship. Adler moved to China in the early 1960s, working in the lead group of the team translating Mao Zedong's works into English.
When the United States reestablished diplomatic contacts with China in 1971, Adler renewed his American citizenship. He died in Beijing on August 4, 1994, two days before his 85th birthday.
Espionage Allegations and Evidence
In 1939, Whittaker Chambers identified Adler to then-Assistant Secretary of State Adolf Berle as a member of an underground Communist group in Washington, D.C., the Ware group. Chambers correctly identified Adler as serving in the General Counsel's Office at the Treasury Department, from which, Chambers said, Adler supplied weekly reports to the American Communist party. In 1945, Elizabeth Bentley identified Adler as a member of the Silvermaster group. A 1948 memo written by Anatoly Gorsky, a former NKVDrezident in Washington D.C., identified Adler as a Soviet agent designated "Sax." This agent, transliterated "Sachs (Saks)" appears in the Venona decrypts supplying information about the Chinese Communists through both Gorsky and American Communist Party head Earl Browder.
In addition to his contacts with U.S. espionage groups, while serving as Treasury attache in China in 1944, Adler shared a house with Chinese Communist secret agent Chi Ch'ao-ting and State Department officer John Stewart Service, who was arrested the following year in the Amerasia case.
Together with Harry Dexter White, Assistant Secretary of the Treasury, and V. Frank Coe, Director of the Treasury's Division of Monetary Research, Adler strongly opposed a gold loan program of $200 million to help the Nationalist Chinese Government control the inflation that took hold in unoccupied China during World War II. Inflation in China between 1943 and 1945 was more than 1,000% per year, weakening the Nationalist government in China. This inflation helped the Communists eventually come to power in China, and in later years White, Coe, and Adler were accused of having deliberately fostered the Chinese inflation by obstructing the stabilization loan.
A Chinese work published in 1983 stated that from 1963 on Adler worked for China's Central External Liaison Department, an organ of the Chinese Communist Party whose functions include foreign intelligence. According to historian R. Bruce Craig, Adler's apartment in Beijing was provided by the Liaison Department, indicating that the Department was Adler's work unit.
