Erwin Aebersold,    ingénieur REG                 >>>"home"...)

Joined Jacques Piccard in 1962 to become
the engineer of the last Swiss submarines to be built.
He designed more than fifteen submarine projects, of which several were actually built, and used.

The best-known among the submersibles which Aebersold conceived, calculated and designed for Jacques Piccard, were :

1 -The “Auguste Piccard” mesoscaphe (PX-8), for the Expo 64 in Switzerland.

This tourist submersible weighing 165 tons was built by Jacques Piccard at the Giovanola plant in Monthey, Switzerland, as the principal attraction of the Swiss National Exhibition in Lausanne in 1964. It was baptized "Auguste Piccard" in honour of Jacques' father, Prof. Auguste Piccard.
Available seats: 40 passengers, one commander, one pilot and one co-pilot.
It transported on board 33'000 passengers and performed 1'100 dives.

2 -The “Ben Franklin" (PX-15), a manned submersible built in Switzerland for exploring the Gulf stream,
This research vessel weighing 135 tons was built by Jacques Piccard at the Giovanola plant in Monthey, for Grummann (Long Island, USA). It was specifically designed for exploring and studying the Gulf stream by drifting along at neutral buoyancy for 30 days without surfacing, in 1969. It covered a distance of 2700 km (1444 Nautical Miles) and was steered by E. Aebersold, who had also conceived, calculated and designed it. .
There were six people on board:
- Jacques Piccard, chief of the expedition,
- 2 scientists of the US Navy, in charge of the oceanographic research,
- 1 NASA scientist, responsible for studying life in close confinement, in preparation for long space flights,
- 1 engineer/captain from Grummann for studying the behaviour of the submarine,
- 1 pilot and project engineer, in charge of technical aspects: E. Aebersold.
E. Aebersold kept a board journal for the test dives and for the entire expedition. See here for a 2-page extract of this journal

3 -The "F.-A. Forel" (PX-28)
The "F.-A. Forel", with 3 places, was in service between 1978 and 2005.

On an idea of Erwin, it was built by Jacques Piccard. at the Giovanola plant in Monthey, a scientific submarine weighing 10 tons, transportable by lorry.
Available spaces: one pilot and two researchers.
Conceived, calculated and designed by E. Aebersold.
