Johann Gottlieb Goldberg (German: [ˈɡɔltbɛɐ̯k]; baptized 14 March 1727 – 13 April 1756) was a German virtuoso harpsichordist, organist, and composer of the late Baroque and early Classical period. He is best known for lending his name, as the probable original performer, to the renowned Goldberg Variations of J. S. Bach.
