Luise Adolpha Le Beau (1850-1927) was a German composer, pianist, and teacher. Le Beau began her musical studies with her father from a young age, including her composition from the age of eight. She later studied with William Kalliwoda in Karsruhe, Clara Schumann (for a summer), Josef Gabriel Rheinberger, and Franz Lachner.
Throughout her studies, Le Beau toured throughout Europe, both as a soloist and with other musicians. Le Beau's compositions were performed through Europe, and she won several international composition competitions. Later in life, she wrote music criticism for several journals, as well as continuing to teach, composer, and perform.
Le Beau was a prolific composer, whose oeuvre includes solo piano works, chamber music, a symphony, two pieces for piano and orchestral, two operas, and dozens of lieder. Though well-known in her lifetime, she remains one of many composers who has sadly fallen out of remembrance
