Monsieur Isabel
Clockmaker
« Isabel à Rouen »
“Isabel à Rouen” is the signature of Monsieur Isabel, who was a clockmaker active in Rouen during the late 18th century. He may be the same M. Isabelle who in 1802 exhibited a system for compensating for the effect of temperature variations on the rate of clocks (see Tardy, Dictionnaire des horlogers français, Paris, 1971, pp. 170).
