John Theodore Comès (January 29, 1873[1] – April 13, 1922[2]) was a Pittsburgh-based architect best remembered for his many buildings for Catholic communities throughout the United States.
His early education occurred in St. Paul, Minnesota, but he earned a Master of Science in architecture from Mount St. Mary's University in Emmitsburg, Maryland.
With the firm of Rutan and Russell, he built St. Augustine Church on 37th Street in the Lawrenceville neighborhood of Pittsburgh.
The firm of Comès, Perry and McMullen is credited with the design of the Blessed Sacrament Cathedral in Greensburg, Pennsylvania, but the building was completed five years after his death.
The marker was placed in front of the former St. Agnes Church at Carlow University, which was designed by Comès and opened in 1917.
