In 1962, he reached a depth of 1000 feet in open ocean.cite journal |author=Wendling, J; Nussberger, P; Schenk, B |title=Milestones of the deep diving resarch laboratory Zurich. |journal=South Pacific Underwater Medicine Society journal |volume=29 |issue=2 |date=1999 |issn=0813-1988 |oclc=16986801 |url=http://archive.rubicon-foundation.org/6003 |accessdate=2008-09-12 ] [Eaton, Bernard (2002) [http://www.divernet.com/cgi-bin/articles.pl?id=2600&sc=1040&ac=d&an=2600:The+Atlantis+affair...

Deep diving

Keller studied philosophy, mathematics, and theoretical physics at the University of Zurich. He became interested in deep diving and developed tables for mixed-gas decompression, supported by Albert Bühlmann who suggested suitable gases. Keller successfully tested his idea in the Lake Zurich where he reached a depth of 400 feet. In 1962, he set a new world record when he reached a depth of 1000 feet off the coast of California, together with Peter Small.cite journal |title=Towards the Limits of the Continental Shelf |author=Keller, H |journal=Historical Diver Magazine |publisher=The Historical Diving Society USA, Inc. |volume=12 |issue=3 |pages= |year=2004 |url=http://www.hds.org/back_issues.html#summer04 |accessdate=2008-09-12 ] This major achievement was overshadowed by the tragic end of the mission: Keller was lucky to survive while Peter Small and Chris Whittaker, a young UCLA student and supporting diver, lost their lives.

In the following years, navies and hospitals bought decompression chambers constructed by Keller.

Career after diving

In the 1970s, Keller sold his own line of computers and in the 1980s became a leading vendor of IBM PCs in Switzerland. He developed a series of software products (Witchpen, Ways for Windows, and Wizardmaker) which provided automatic spell checking, literal machine translation, and macro recording.

He now runs [http://www.visipix.com Visipix] the largest Fine Art and Photo Museum online with 1.3 million exhibits, all with Free Copyrights for any use.

Since 2005, Keller has been a full-time artist.
