Architects & Artisans

George D Barnett of Barnett, Haynes, and Barnett of Saint Louis designed the entire structure of the Cathedral including a circular Sacristy on the north end which was not built when the main structure was completed in 1914. The semi-circular Sacristy which was eventually built was designed by George John Magualo of Magualo and Quick.

Barnett also designed the main Altar, the baldachino, and the Lower Sanctuary mosaics. The mosaics were installed by the Gorham Company of New York in 1916. Barnett also designed the Blessed Sacrament Chapel and its mosaics which were installed by Gorham in 1916 and 1917.

George John Magualo of Magualo and Quick of Saint Louis was the architect in charge of the Cathedral Basilica when the sacristy was built and when the major work on the mosaics was resumed under Cardinal Ritter, which had been interrupted by the depression and World War II.

Joseph Murphy of Murphy and Mackey of Saint Louis served as the official architect of the Cathedral Basilica who oversaw the major seven-year exterior renovation program that corrected a moisture problem that was disintegrating the granite walls and roof. He also designed the mosaic shrine of Our Lady of Perpetual Help.

Verner Burks, Jr. of Saint Louis subsequently served as the designated architect of the Cathedral and was on the committee that planned and oversaw the installation of the final mosaics. He also designed the reinstallation of the organ that now reveals the stained glass window and mosaics previously obscured by the old organ. He also designed the structure of the Mosaic Museum.

Chevalier Aristide Leonori designed the Blessed Virgin and All Saints Chapel, and the mosaics in them. The fabrication and installation of the Chapels and mosaics were handled by the Tiffany Company in 1912.

Robert Frei of Saint Louis designed & fabricated all the stained glass windows on the balcony level.
