J. Milton Dyer (April 22, 1870 – May 27, 1957) was a prominent Cleveland, Ohio architect.
Dwyer was born in Middletown, Pennsylvania where his father had a hardware business. In 1881 his family moved to the Rock's Corners area (near East 55th and Woodland Avenue) and Dyer attended Central High School, worked for Brown Hoisting where he earned a scholarship to Case Institute of Technology. He later studied at the École nationale supérieure des Beaux-Arts in Paris.
He worked for Warner & Swasey (Ambrose Swasey and Worcester R. Warner's firm) for several years, and Frank Walker, Henry Weeks, and Reynold Hinsdale worked in his office. The Architectural Record published a 1906 feature that noted him as an example of professionally educated architects moving to smaller cities.
Dyer was a member of Cleveland's Tavern Club, established 1892-93, and designed a building for the group when it moved from a leased property at 968 Prospect Street to its present building on 1 January 1905. "The exterior construction and the traditional interior decor of the building" have remained essentially the same since the club's beginning. He designed several buildings on Cleveland's Euclid Avenue.
J. Milton Dyer was selected as the architect for an exhibition of Cleveland products staged in 1909 called the Spirit of Progress. Erected in 47 days (March 30-May 24), the Exposition Building is said to have had "a larger ground floor exhibit area than any other exposition structure in the United States" with 72,030 square feet (6,692 m2) as well as the area of an armory and a bridge connecting the two buildings, for "a grand total of 114,656 square feet, a space greatly in excess of that of any previous home product exhibition".
