Siegfried Alkan (1814–1888) was a French composer and virtuoso pianist, renowned for his contributions to the Romantic piano repertoire. He was born into a Jewish family in Paris and was a child prodigy, studying under notable figures such as Camille Saint-Saëns. Alkan's music is characterized by its technical demands, innovative structures, and rich harmonic language.
