Joseph-Martin Cabirol

Joseph-Martin Cabirol was a French man who patented a new model of standard diving dress in Paris in 1855, based on Augustus Siebe's designs, and afterwards he made them. 
Joseph Martin Cabirol was born in Narbonne on March 28, 1799. He was the son of Jean Guillaume Cabirol, trader and Marie Lescot. On April 1st, 1829, he married in Bordeaux Anne Caroline Royère, the daughter of a pension master in Béziers. He dies 168 Marsal street in Paris, 9th district, on December 15, 1874 at the age of 75. 
The suit is made out of rubberized canvas. The helmet, for the first time, includes a hand-controlled exhust valve that the diver uses to evacuate his exhaled air. The valve included a non-return valve which stops water from entering the helmet. Until 1855 diving helmets were equipped with only three circular windows (front, left and right sides). Cabirol's helmet introduced the fourth window, in the upper front part of the helmet, which gives the diver an upward view. Having been presented to the "Exposition Universelle" in Paris Cabirol's diving dress won the silver medal. This original diving dress and helmet are now preserved at the "Conservatoire National des Arts et Métiers" in Paris.
His gravestone has a carving of a goat on it, as 'cabirol' is Occitanian for "goat".
