Leonardo De Lorenzo (August 29, 1875 – July 29, 1962) was a prominent Italian flutist, music educator, and composer. He is recognized for his contributions to the technical development of flute performance and for his historical documentation of the instrument.
Born in Viggiano, Italy, De Lorenzo began his musical studies at the Conservatory of San Pietro a Majella in Naples. After a period of traveling and performing internationally, including service in the Italian military band, he emigrated to the United States in 1909.
In America, De Lorenzo held principal flute positions with several major orchestras, including the New York Philharmonic, the Minneapolis Symphony Orchestra, and the Rochester Philharmonic Orchestra. From 1923 to 1935, he served as a professor of flute at the Eastman School of Music in Rochester, New York.
De Lorenzo is widely noted for his pedagogical and historical writings. His most significant work, My Complete Story of the Flute (1951), is an extensive treatise that details the history of the instrument, its evolution, and the lives of notable flutists. He also composed numerous instructional works and solo pieces for the flute, such as L'Indispensabile, a comprehensive method for the instrument.
Following his retirement, De Lorenzo moved to California, where he continued to collect and organize materials related to flute history. His archives and collections were eventually donated to the University of Southern California. In his honor, the "Leonardo De Lorenzo" International Flute Competition was established in his birthplace of Viggiano to promote young musical talent.
