The first swimming dress submitted by Father La Chapelle in 1765 to the Academy of Sciences was described as a no sleeves jacket which was going to hips. A strip of cloth, fixed onto the bottom of the back, went between the legs to be fixed in front. Cork square pieces were fixed on the jacket to support swimmer near the surface in vertical position. That jacket, named "scaphandre" (" boat-man" in Greek language) by its inventor was admitted by the Academy that it had a great utility in case of wrecks because it was fast to slip by sailors they didn't know swimming. It also allowed troops crossing rivers or unloading from boats without berthing. When he showed his jacket, La Chapelle added trousers and a hat where swimmer could shelter personal items.
