Benjamin S. Adamowski (November 20, 1906 - March 1, 1982) was a politician and lawyer.
His father, Max Adamowski, was an alderman in Chicago, as well as a real estate agent in Logan Square, and tavern owner.[1] He graduated from DePaul University Law School in 1928.
He served in the Illinois House of Representatives, representing the 25th District from 1931 through 1941.[2] In the legislature, he distanced himself from the machine politics his father had been aligned with, and aligned himself with liberal reformist governor Henry Horner.[1] In 1940, Adamowski unsuccessfully sought the Democratic nomination in the special U.S. Senate election.[3]
In 1941, Adamowski left the legislature to serve as the Corporation Counsel of Chicago under Mayor Martin H. Kennelly, a role he held for at least three years.[1]
He was a Democrat until 1955, when he was defeated by Richard J. Daley in the Democratic primary for mayor. In later campaigns for State's Attorney and a second bid for mayor against Daley in 1963 he ran as a Republican.[4]
He served from 1957 to 1960 as State's Attorney of Cook County.[5] In May 1959, he uncovered a $500,000-a-year ticket-fixing scandal in Chicago Traffic Court, and indicted four court employees on corruption charges.[1]
