James Knox Taylor (October 11, 1857 – August 27, 1929) was Supervising Architect of the United States Department of the Treasury from 1897 to 1912.
His name is listed ex officio as supervising architect of hundreds of federal buildings built throughout the United States during the period.
He attended Massachusetts Institute of Technology where he was a classmate of William Martin Aiken, who would precede him in the position of Supervisory Architect, and Cass Gilbert.
The competitions were met with enthusiasm by the community but were also marred by scandal, as when Taylor picked his ex-partner Cass Gilbert for the New York Customs House commission.
[5] From 1897 through 1912 Taylor is credited as "supervising architect" for federal buildings constructed during his tenure, a list which includes dozens of post offices, court houses and other structures.
