Julian Sidney Rumsey (April 3, 1823 in Batavia, New York – April 20, 1886 in Chicago, Illinois) served as mayor of Chicago, Illinois (1861–1862) for the Republican Party.
Career
Rumsey arrived in Chicago on July 28, 1835, to work in a shipping company owned by his uncles.
He and his brother subsequently became partners. This firm, then known as Newberry and Dole, sent out the first shipment of grain from Chicago in September 1839. In 1852 Dole retired, and the firm, which was for a time known as Rumsey Brothers, devoted itself exclusively to the grain commission business.
Rumsey was identified with the history of Chicago for more than half a century. During that period he was mayor, county treasurer, and president of the Chicago Board of Trade. He was a charter member of the Board of Trade, and through his efforts the present system of grain inspection and grading was adopted. This achievement gave him the title of the "Father of Grain Inspection."
Rumsey always took an interest in national and state politics.
