Philippe-Antoine Magimel struck his mark in 1721 and was garde du Corps de l'Orfèvrerie de Paris in 1736/1737, 1737/1738 and 1751/1752. In 1751, his nomination as grande-garde was empeached by the opposition of Noël Hardivilliers, Alexis Porcher and several other ex-gardes, whereas Julien Berthe acted in his favour. Nevertheless, Magimel became grande-garde in 1752 and consul in 1759. He died in 1772, aged 80.
