Gottfried Heinrich Bach (26 February 1724 – 12 February 1763 (buried)) was the firstborn son of Johann Sebastian Bach by his second wife Anna Magdalena Wilcke. Born in Leipzig, Gottfried Heinrich became "feeble-minded" (mildly mentally handicapped in some way) at an early age, but he played the keyboard well and C. P. E. Bach is quoted as saying that he showed "a great genius, which however failed to develop". From 1750 he lived with his brother-in-law Johann Christoph Altnikol.[1] He died in Naumburg.
