Petitcollin is a French toy manufacturing company that was founded in 1865 by Nicolas Petitcollin. It is the last French factory of Swimmers, Poupons and traditional dolls still operating. Petitcollin began working in celluloid in the late 1800s, and eventually specialised in manufacturing products made from polyester resins.
During World War I, the Petitcollin factory in Étain was completely destroyed. However, Petitcollin thrived during the interwar period. Around 1924-1926, the Petitcollin company innovated by launching on the market a baby doll which can be bathed, the swimming doll "Petit Collin". Eventually, Petitcollin decided to specialise in manufacturing products made from polyester resins. In 1961 it became the first French manufacturer of polyester resin helmets, operating from a rebuilt factory in Étain.
