Benno Janssen was born in Saint Louis, Missouri, the son of Oscar Janssen and Thekla Susenbeth.
Janssen studied at the University of Kansas. In 1902, Janssen headed for Paris, France, and further studied at the École des Beaux-Arts.
In 1899, he began working in architecture in Boston, Massachusetts. He also continued his studies at the Massachusetts Institute of Technology. In 1905, he returned to the United States to work in Pittsburgh, Pennsylvania, for the architectural firm MacClure & Spahr.
Janssen next joined with William York Cocken in 1922, and together they started the architectural firm Janssen & Cocken.
He is best known for monumental buildings such as the Pittsburgh Athletic Association (1911), the Masonic Temple (1915 - now Alumni Hall of the University of Pittsburgh), William Penn Hotel (1916 and again in 1928), Mellon Institute (1937), the Longue Vue Club (1923), Rolling Rock Club and Stables (1928 - near Ligonier, Pennsylvania), the T.W. Phillips Gas & Oil Company (Butler, Pennsylvania), the Keystone Athletic Club (1929 - now Lawrence Hall of Point Park University), and the Washington Crossing Bridge (Pittsburgh), also called the 40th Street Bridge (1924). Janssen also designed many fine residences, including the country estate of George Calvert (1912).
The Lee L. Chandler House (1924) in Shadyside. Elm Court, the estate of Bachelor of Divinity Phillips in Butler, Pennsylvania (1929).
As well as Fox Chapel"s Frank B. Ingersoll House (1931) and Louisiana Tourelle, the Edgar J. Kaufmann house (1923).
Janssen received many Kaufmann commissions over the years. The prevailing architectural motif of these Benno Janssen homes was a picturesquely irregular configuration of buildings rambling around a central courtyard. Other features these homes shared include: complex slate roofs with many gables, large groups of rectangular windows, rich oriel and bay windows, interesting chimney treatments, and intricately carved stone detailing.
Many of Janssen"s buildings also boast museum-quality wrought-iron by noted Philadelphia artisan Samuel Yellin.
Janssen collaborated with Yellin for 25 years, resulting in gracious iron details in his most important projects.
