Portrait of John Alcock by Robert Cooper (d. 1828). It is unclear whether it is of John Alcock (1740-1791), as stated by the Scottish National Gallery,[1] or of his father, John Alcock (1715–1806), as stated by the National Portrait Gallery.[2]
John Alcock (bapt. 28 January 1740 – 30 March 1791) was an English organist, who composed several songs between 1770 and 1780.
