Born on the 23rd August 1891 in Orthez, Paul Louis Mergier, whose father was a maths teacher, belonged to a family of four children. In his autobiography he recounts how, at a young age, he loved reading art journals, and how, during the holidays he would break into the studios of the Ecole Normale in Cahors and spend hours trying out all the carpentry, locksmith and forgery tools.
However, having been a pupil of the Ecole Breguet, it was in Paris, where in 1909 he became a student at the Ecole Supérieure de l'Aeronautique, that his artistic vocation was established.
At the same time as his studies in engineering (which he eventually became entirely disenchanted with) he attended courses led by André Lhote and Lycien Marne at the Conservatoire des arts et métiers. Passionate about antiques, he became a dealer at 226, boulevard Raspail, but, as the pieces he made himself seemed to please his clients more, he opened his own cabinetmakers. His interest in traditional arts led him to become a painter, enameller, cabinetmaker, coppersmith and theorist.
Paul Louis Mergier's work has been offered at auction multiple times, with realized prices ranging from $500 to $7,500, depending on the size and medium of the artwork. The artist died in 1986.
