Charles Francois first worked with Nicolas Lupot from 1802 to 1810, then joined his father's workshop (some of the instruments from this period are labeled as made between 1807 and 1816).
[1] At the death of his father in 1820, Charles François Gand took over the workshop of Jean Gabriel Koliker at 24 rue Croix-des-Petits-Champs in Paris.
His collaborators in the shop included: Auguste Sebastien Bernardel, Georges Chanot (1821), Joseph Louis Germain (1840–1845) and Pierre Silvestre (1824–1829).
He completed a set of instruments begun by Lupot for the Royal Orchestra, but most of them were destroyed in a fire at the Tuileries in 1871.
Charles Francois Gand is ranked as a serious rival to both Nicolas Lupot and Jean-Baptiste Vuillaume as a luthier.
