History

Deep-dive experiments and events such as 1961, the world record dive by the Swiss Hannes Keller to a depth of 305 meters near the island of Santa Catalina, California, aroused the interest of various industries on the activities of man under water.

How this success came about, and what happened next, has been historically reappraised by A. A. Bühlmann's son Thomas. You can read an extensive and richly illustrated presentation of his work on the Cronatec site.
