Thompson, the son of Alonzo and Sarah (Edwards) Thompson, was born Christmas Day in 1887 on a poor farm in Roodhouse, Illinois.
Thompson never attended university or law school, but he studied for the bar examination on his own, and in 1911, he was admitted to the bar of Tennessee and Illinois.
He is perhaps best known for representing American businessman Samuel Insull, who in 1934 faced mail fraud and antitrust charges. Insull"s verdict was not guilty. Thompson worked on the family farm while he was in school.
After graduation, he spent three years working as a teacher.
He established a law practice in East Moline, Illinois, and also became publisher of the East Moline Herald. In 1919, a vacancy arose on the Supreme Court of Illinois when Justice George A. Cooke stepped down to become chief counsel of Peoples Gas Light and Coke Company, and Thompson ran for this seat, winning election in April 1919.
Thompson served on the Illinois Supreme Court until 1928, during which time he served as chairman of the American Bar Association"s Section of Criminal Law (1921–1923) and as vice-president of the American Institute of Criminal Law and Criminology. In 1928, Thompson resigned from the Illinois Supreme Court to run for Governor of Illinois on the Democratic ticket.
He lost to Louis Lincoln Emmerson as part of the landslide 1928 victory of Herbert Hoover and the Republicans.
Upon his defeat, Thompson became a partner at Newman, Poppenhusen, Stern & Johnston, with the firm changing its name to Johnston, Thompson, & Raymond (today, the firm is known as Jenner & Block). During his time at the firm, Thompson served as lead counsel in what was arguably the most sensational prosecution of the Great Depression era, that of Samuel Insull, the president of Commonwealth Edison, whose share price had collapsed in 1929, wiping out the life savings of thousands of small investors. Insull was charged with mail fraud, antitrust violations, and violation of the Bankruptcy Acting of 1898.
There were ultimately three trials, and Insull was acquitted each time.
He was president of the Illinois State Bar Association 1933-1934. Tucker, Cerf, and all the other defendants were ultimately acquitted on all charges.
In 1949, during the prosecution of Preston Tucker (developer of the 1948 Tucker Sedan) and six Tucker Corporation executives for violating the securities laws, Thompson defended Floyd Cerf, the stockbroker who handled the allegedly illegal stock offering for Tucker Corporation.
He was a charter member of the American Law Institute upon its founding in 1923.
