Winterthur (pronounced Ger /vɪntərtur/ Eng /tʊər/ is a city in the canton of Zurich in northern Switzerland. The meaning of the term deep diving is a form of Technical diving. In 1962, he reached a depth of 1000 feet in open ocean. Year 1962 ( MCMLXII) was a Common year starting on Monday (the link is to a full 1962 calendar of the Gregorian calendar.

Keller studied philosophy, mathematics, and theoretical physics at the University of Zurich. Philosophy is the study of general problems concerning matters such as existence knowledge truth beauty justice validity mind and language Mathematics is the body of Knowledge and Academic discipline that studies such concepts as Quantity, Structure, Space and Theoretical physics employs Mathematical models and Abstractions of Physics in an attempt to explain experimental data taken of the natural world The University of Zurich ( German: Universität Zürich) located in the city of Zurich, is the largest University in Switzerland 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. Lake Zurich ( Swiss German / Alemannic: Zürisee; German: Zürichsee) is a Lake in Switzerland, extending 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. California ( is a US state on the West Coast of the United States, along the Pacific Ocean. 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. The University of California Los Angeles (generally known as UCLA) is a public research university located in Westwood Los Angeles, California, United
In the following years, navies and hospitals bought decompression chambers constructed by Keller. A decompression chamber is a Pressure vessel used in Surface supplied diving to allow the divers to complete their Decompression stops at the end of a dive
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. In Computing, a spell checker is an applications program that flags words in a document that may not be spelled correctly Machine translation, sometimes referred to by the abbreviation A macro (from the Greek 'μάκρο' for long or far in Computer science is a rule or Pattern that specifies how a certain input sequence (often a sequence
