BY SENÉ & DETALLA (FL. C. 1795-1805), MARKED, GENEVA, CIRCA 1800

The partnership of the Geneva goldsmiths Philippe Sené and Détalla must have existed since sometime before 1795 but seems to have split up in 1805. By October 1805, Sené had gone into partnership with his brother-in-law Henry Neisser who had come to Geneva from Hanau in 1785/1786. Sené died in November 1807 and Neisser entered a mark on his own account in 1808.
