Pierre Louteau worked in Lyon between 1603 and 1628 and is variously described as 'Maestre Horlogeur', 'Horlogier' and 'Orlogeur'. On 4th of January 1607, he married Marie Vannier who is especially mentioned as having been a protestant. Louteau himself was of the same faith and appears in the rolls of huguenots belonging to the town of Lyon.
Watches signed by Louteau are recorded in some of the world's most distinguished collections such as J. Pierport Morgan Collection, Gélis Collection, Spitzer Collection, Marryat Collection, the Rijksmuseum Amsterdam and the Hilton Price Collection.
Léon Leroy (1876-1961) was a direct descendant of the famous French watchmaking dynasty of the Leroy family founded in 1785 by Charles Bazile Leroy.
The business was taken over by Léon Leroy in 1935 after the death of Louis Leroy and was directed by him until his death in 1961 when he was succeeded by his brothers Pierre and Philippe.
Léon Leroy devoted a large part of his time to collecting books on the history of French horology. His collection, containing numerous items of greatest rarity, was offered at public auction in Paris in 1982.
