JACKSON, WILLIAM (1730-1803), English musician, was born at Exeter on May 29, 173o. He published many works during his lifetime, the most famous of which were Twelve Songs ( 755), which deserved their great popularity. But he is remembered only for his Te Deum (Jackson in F), which was a popular favourite in Church music for over a century. He died at Exeter, where he passed the greater part of his life, on July 5, 1803.
