The Amadio family were prolific instrument makers throughout the first half of the Nineteenth Century. As is evident from the name, the family were of Italian heritage and like most Italian emigrant instrument makers of this period, were most likely to have originated from around the Lake Como region of Northern Italy.

The maker of this fine example, Francis Amadio is considered to have arrived in London at the turn of the century but is initially registered as a maker of artificial flowers. Exactly how Amadio was trained in the arts of instrument making and by whom remains unclear, but it suggests that he received his training after his arrival. His earliest dates reflecting his instrument making career start at 1820 at St Johns Street Road and he maintained business within the street until the turn of the 1840’s.

Francis had two sons, Francis Junior and Joseph, the former seems to have joined his Father in business from about 1840 to form Francis Amadio & Son. Three years later, Francis Amadio senior died, leaving Francis Junior in sole charge of the business which he seems to have continued throughout the 1850’s and 1860’s until he finally joined forces with his younger brother Joseph.

The younger sibling ran a very successful business latterly more concerned with the new industry relating to microscopy and with Francis Junior’s death in 1866, he continued to trade for many years under his own name. He died during retirement in 1892.

Circa 1830
