This document is an overview of the life and career of the architect Ulysses Grant Fay, who was born in Rochester, New York in 1865 and moved to Seattle in 1906, where he died in 1918. Relatively little was known about Fay until my research on the design and construction of the Masonic Building at the 1909 Alaska-Yukon-Pacific Exposition. This document is a compilation of information on Fay that I found in vital statistics records, censuses, newspapers, trade publications, periodicals, directories, and other sources. It is intended as a study guide and reference work for others interested in the life of this relatively obscure figure in the architectural history of the Pacific Northwest.
