Carroll Leach Meins was a political figure who served as a member of the Massachusetts House of Representatives, Chairman of the Massachusetts Republican Party, and Collector of Customs for the Port of Boston.
After the war, Meins served as treasurer of the Sparrow and Meins Chocolate Company.
Meins was a member of the Massachusetts House of Representatives from 1923 to 1929. During his tenure he was chairman of the House Committee on Taxation and was a member of the Committee on Rules.
In 1937 he was elected Chairman of the Boston Republican Committee.
On May 4, 1938 Meins was elected Chairman of the state Republican Party. During his tenure as Chairman, Republican Leverett Saltonstall was elected Governor of Massachusetts. Saltonstall chose Meins to serve as Secretary to the Governor. He was succeeded as party chairman by George W. Schryver on December 14, 1938.
Meins served as chief secretary to Governor Saltonstall from January 5, 1939 to December 11, 1940 when he accepted an appointment to the State Public Utilities Commission.
In 1947, Meins was appointed by Robert F. Bradford to head the newly created Metropolitan Transit Authority. Although Meins had a ten-year term, on January 5, 1949, he and the four other members of the Metropolitan Transit Authority Board of Trustees resigned, as they believed incoming Governor Paul A. Dever was entitled to appoint his own board. Dever had been expected to remove the trustees, as the MTA system had run a $9 million deficit under their leadership.
