I have a book published in 1969 called "The Complete Guide to Skin and Scuba Diving" by Hank and Shaney Frey. At that date the text says "limit your diving to 130 feet." However, they include in the appendix the Navy Decompression tables for decompression stops for dives up to 190 feet. In another place they give no decompression times for dives to as deep as 190 feet. That's as far back as I have a resource that addresses your question, sort of. Do not take the infomation as a dare, please.

On a large pile of smokin' A'a, the most isolated population center on the face of the earth. 2,175 miles to Alaska, 2,390 miles to California; 3,850 miles to Japan; 4,900 miles to China; 5,280 miles to the Philippines.
The 130 foot recreational diving limit is based on a misunderstanding (that has turned into a liability convenience) of a U.S. Navy operational guidelines that SUGGESTS, for reasons of efficiency, moving from scuba to surface supplied air at 130. On the other hand the science community's 190 ft. limit is based on the need, at that depth, to move from the better tested U.S. Navy Standard Air Tables to the U.S. Navy Exceptional Exposure Tables that are no where near as well tested.
In answer to the OP's original question. If my memory of long ago is any good Dumas told me the that during the war they went to about 60 meters.
I refuse to believe that corporations are people until Texas executes one.

Dumas' 62 meter dive (I since looked it up) predates that video, I believe, since it was with a prototype aqualung.
In October of 1943, not knowing about Commeinhes exploit, Dumas dove with a Cousteau-Gagnan prototype and reached 62 metres off Les Goudes, not far from Marseille. He felt then what is now called nitrogen narcosis - Jacques-Yves Cousteau & Frédéric Dumas, Le Monde du silence, Éditions de Paris, Paris, 1953, Dépôt légal 1er Trimestre 1954 - Édition N° 228 - Impression N° 741 (pp. 35-37, in French)

Have been traveling...and going to beach every day..75 degress and sunny today
The first ocean dive made at Bardol off the coast of France.
The dive you posted occured much later,
The first dive was in the Marne river with a converted gasogen configured with one hose like the R/D unit produced in the 1860s. It was a failure, so they added the second hose and dove again with sucess several weeks later.
This is based on my personal research and many conversations with JYC & EG--who was the designer of the Aqualung...FYI I was the US Divers company instructor for many many years..
