Philip H. Frohman

Philip Hubert Frohman (November 16, 1887 – October 30, 1972) was an architect who is most widely known for his work on the Washington National Cathedral, named, the "Cathedral Church of St. Peter and St. Paul" in Washington, D.C. He worked on the English Gothic style cathedral from 1921 until his death in 1972.

Frohman was born in Hotel Chelsea, designed by his grandfather Philip Gengembre Hubert, in New York in 1887 to Gustave Frohman, a theatrical producer, and the former Marie Hubert, an actress.

Frohman had a notable lineage in the related worlds of architecture and engineering. In 1849, his grandfather Philip Gengembre Hubert and his great-grandfather Charles Antoine Colomb Gengembre moved to America. While practicing architecture in New York, Hubert designed the Hotel Chelsea, later to become a well-known residence for actors, writers, musicians and other artists. Built in 1883, it had the distinction of being the tallest building in New York until 1899. Initially constructed as an apartment building, it still remains in operation today, as a hotel. His great-grandfather, Charles Antoine Colomb Gengembre, both an architect and civil engineer, supervised the building of the first railway from Liverpool to Manchester. His great-great-grandfather was Philippe Joachim Joseph Gengembre, who served as Director of Works for King Louis Philippe of France in the early 19th century. Gengembre designed France’s first steam warship and the first home in Paris to feature gas lighting.

Frohman’s interest in architecture was evident even in his early years. At the age of eleven, he enrolled in the Throop Polytechnic Institute in Pasadena, California, where he attended grammar school and secondary school. (Throop later spun off its grammar and secondary schools into Polytechnic School, while Throop itself became the California Institute of Technology.) He designed his first house when he was fourteen. In 1907, he graduated and became the youngest person ever to pass the state architectural examination. The following year, at the age of twenty-one, he opened his own office in Pasadena. In his early practice he focused on the design of both churches and houses. Early Frohman-designed churches include Trinity Episcopal Church in Orange, California in 1909, and other parish churches in Santa Barbara and Inglewood, California between 1909 and 1917.
