In 1924 Mary Louise Bok founded the Curtis Institute of Music in Philadelphia, which she dedicated to her father, Cyrus Curtis, and in 1927, the Boks embarked upon the construction of Bok Tower Gardens, near their winter home in Mountain Lake Estates, Lake Wales, Florida, which was dedicated on February 1, 1929, by the president of the United States, Calvin Coolidge. Bok Tower is sometimes called a sanctuary and is listed on the National Register of Historic Places as a National Historic Landmark. Bok is used as an example in Dale Carnegie's "How to Win Friends and Influence People."
