As Postmaster General, he was an ardent opponent of obscenity. Early life and career Summerfield was born in Pinconning, Michigan, on March 17, 1899, the son of Cora Edith Ellsworth, (Born in Indiana on April 11, 1877 - Died in Flint, Michigan, on January 18, 1933) and William Henry Summerfield, (Born in Zilwaukee, Michigan, in 1876 - Died in Flint, Michigan, in 1938).

Arthur Ellsworth Summerfield, Jr. Political career Summerfield served as the chairman of the Republican National Committee between 1952 and 1953. At the 1952 Republican National Convention he played a key role in winning the GOP presidential nomination for General Dwight Eisenhower. As Michigan's delegate chairman Summerfield convinced the large, uncommitted Michigan delegation to support Eisenhower, thus providing "Ike" with a major boost before the voting. In December 1952, President-Elect Eisenhower chose Summerfield as the federal Postmaster General; he served in that post from 1953 until 1961. His assistant postmaster was former U.S. Representative Ben H. Guill of Texas. As postmaster general, Summerfield oversaw attempts to reform and modernize the Post Office and the U.S. mail system, which was still conducting many sorting and processing operations by hand. Summerfield called for an increase in postage rates to subsidize the purchase of new mechanized mail processing and sorting equipment. Some of this equipment was adopted, including the Hamper-Dumper internal mail sorting/transport system and the Mail-Flo Letter Processing System, which used conveyors to speed mail processing. However, rapidly increasing mail volume and postal deficits prevented the Post Office from completely modernizing and mechanizing all of its many post offices. To improve the Post Office's image with the public, Summerfield began a promotional campaign designed to showcase Post Office achievements.
