    Architect Paul Phillippe Cret combined the best of his Ecole des Beaux-Arts schooling in Paris with an sense of modernity gleaned in the US. In his 1930 design for the Federal Reserve Bank of Philadelphia, built by Irwin & Leighton, he advanced toward the perfection of his trademark style later used in creating the Federal Reserve Board Building in Washington, DC. Now known as the Old Federal Reserve Building, the Chestnut Street location was added to the National Register of Historic Places in 1979. #ourfirst100years Thomas Jefferson University Hospitals Sidney Kimmel Cancer Center – Jefferson Health

    Built in by Irwin & Leighton in 1927 for the newly formed Fidelity-Philadelphia Trust Co., this building is known to us today as the Wells Fargo Building. The massive 600,000 sf building remains a strong and proud presence on S. Broad Street. This was one of the last Beaux-Arts skyscrapers to be built in America before the Great Depression. Completed in less than one year and one month ahead of schedule the project contained 2,600 bronze windows, 8,000 sf of granite, 100,000 sf of limestone and 140,000 sf of marble. Movie buffs will remember that the building served as the headquarters of Duke & Duke in the 1983 movie, Trading Places. #ourfirst110years Wells Fargo
