The performance history in the nineteenth century can be traced back to the circle of Felix Mendelssohn. In the first decade of the 19th century the harpsichord virtuoso and great aunt of Mendelssohn, Sara Levy, gave public performances of the concerto in Berlin at the Sing-Akademie, established in 1791 by the harpsichordist Carl Friedrich Christian Fasch and subsequently run by Mendelssohn's teacher Carl Friedrich Zelter. In 1824 Mendelssohn's sister Fanny performed the concerto at the same venue. In 1835 Mendelssohn played the concerto in his first year as director of the Gewandhaus in Leipzig. There were further performances at the Gewandhaus in 1837, 1843 and 1863. Ignaz Moscheles, a friend and teacher of Mendelssohn as well as a fellow devotee of Bach, gave the first performance of the concerto in London in 1836 at a benefit concert, adding one flute and two clarinets, bassoons and horns to the orchestra. In a letter to Mendelssohn, he disclosed that he intended the woodwind section to have the "same position in the Concerto as the organ in the performance of a Mass." Robert Schumann subsequently described Moscheles' reorchestration as "very beautiful." The following year Moscheles performed the concerto at the "Academy of Ancient Music" with Bach's original string orchestration. The "Musical World" reported that Moscheles "elicited such unequivocal testimonies of delight, as the quiet circle of the Ancient Concert subscribers rarely indulge in." In 1838 the concerto was published in Leipzig. Johannes Brahms later composed a cadenza for the last movement of the concerto, which was published posthumously.
