Theodore C. Link (March 17, 1850 - November 12, 1923) was a German-American architect.  Born in Germany, Link trained in engineering at the University of Heidelberg and, later, at l’Ecole Centrale in Paris before moving to the United States in 1870. After working for railroads in New York, Philadelphia and Texas, he came to St. Louis in 1874 as an employee of the Atlantic and Pacific Railroad.  The following year he delineated Forest Park plans authored by Julius Pitzman and Max Kern—Chief Engineer and General Superintendent of Forest Park respectively.  Impressed, Pitzman recommended him for the city post of Superintendent of Parks, a position Link held from 1876 through 1877.  Next Link spent four years in Pittsburgh, Pennsylvania where he published two German-language newspapers before returning to St. Louis in 1882 to open a civil engineering office.

Link served as one of the architects for the 1904 World’s Fair and he was also selected to design the first Carnegie Library to be built in St. Louis, the Barr Branch at 1701 South Jefferson Avenue constructed in 1905.  Other landmark structures include Second Presbyterian Church (1899) at 5401 Westminster Place, St. John’s United Methodist Church (1901) at 5000 Washington Place, the Wednesday Club (1908) at 4500 Westminster Place, the Oscar Johnson House (1908) at 38 Portland Place, the International Shoe Company Headquarters (1909) at 1601 Washington Avenue and three houses from 1911 on Delmar in University City for a shoe-magnate family.

Link practiced on his own from 1882 before entering a brief but productive partnership with Edward Cameron from 1891-1892.  Then came two more years alone, followed by a 1895-1896 triumvirate with Alfred R. Rosenheim and William B. Ittner which was in turn (1896-98) succeeded by Link and Rosenheim.  Over a decade passed before Link would form another two-year partnership, this one in 1910 with his son Carl.  In 1919, Link teamed up with architect Wilbur Tyson Trueblood to come up with a master plan and then design at least nine buildings for the campus of Louisiana State University in Baton Rouge.
