“Chappel & Comp.
The firm is said to have commenced in 1812 at 124, New Bond Street, (premises which had been occupied previously by Goulding & Co.), with Samuel Chappell at its head and the two musicians, J. B. Cramer & Francis Tatton Latour, as partners. About 1819 or perhaps a year or so later Cramer left, and in 1824 founded a business of his own, while in 1826, Latour did the same, taking 50, Bond Street, a shop almost opposite the old one….

S. Chappell published music under his own name at 135, New Bond Street. In 1830 Chappell is said to have bought Latour's business and had established himself on the latter's premises, No. 50, and was in business alone. He died in December 1834, leaving his widow and his two sons, Thomas and William, as his successors.

About 1845 William Chappell, author of popular music, left his brother and became partner with Cramer & Co. The modern firm of Chappell is of course well known….

Latour, Francis Tatton.
Was first in business. with Samuel Chappell, but about 1826 founded one of his own at 50, New Bond Street, where he published sheet music. About 1830 Chappell bought Latour's stock and copyrights and removed into his premises.”
