I have trouble with email attachments and some of you might be curious. Here is the extent of the mention of bobbins. The Nov. 1965 News article is The Climbing Cam: A New Ascender, by Henshaw and Morehouse. It describes the design that was commercialized as the Gibbs. The French ascender mentioned may be the one on page 4 of this PDF.

Gary, et al,

As a result of this thread I emailed Jean-Francois Pernette in France to ask him about who invented the bobbin. He just phoned me (easier to speak then to write English) and mentioned it was Bruno Dressler from whom he first bought the devices in the middle 60s. He didn't know when Petzl began making them.

So, armed with that info I did a bit of googling and copied this out of a Petzl Company history page:

In 1968, Bruno Dressler presented three products to him: ancestors of the chute (system of fixed flask pulleys) and of the blocker-on-cord (ascenders?). He took these as a starting point for the process, reverse engineered them, and then developed the new finished products. These, the first tools of the revolution in the techniques of descent and ascent on rope, are ready. The speleologist discovered his autonomy, and the new prospects for exploration that the new tools offered.


The entire article is here. It is translated from French and is a little hard to read.
