Timeline: A history of the Curtis Institute of Music

Since its founding in 1924, the Curtis Institute of Music in Philadelphia has been considered one of the world’s leading classical music conservatories. It was founded by Mary Louise Curtis Bok, with an inheritance from Cyrus H. K. Curtis and the Curtis Publishing Company (Saturday Evening Post, The Ladies’ Home Journal) and with artistic guidance from Philadelphia Orchestra director Leopold Stokowski and renowned pianist Josef Hofmann.

To house the new conservatory, Edward and Mary Louise Curtis Bok purchase three buildings on Rittenhouse Square at Locust Street–-the Romanesque home of the prominent Drexel family, the adjoining Sibley house, and the Beaux Arts–style Cramp mansion.


The Curtis Institute of Music is chartered on April 18, Leopold Stokowski's birthday, by the Commonwealth of Pennsylvania "to train exceptionally gifted young musicians for careers as performing artists on the highest professional level."
