Author of Computer books

Klaus was born on 23 April 1968 in Saskatoon, Canada, where his father, Hans Breuer, was professor of Physics at the University of Saskatchewan and his mother a graduate student in Romance languages. His parents took him on many large journeys, which included Yellowstone Park and Nevada, a trip to Vancouver and even a visit to Germany and to the Libyan Sahara. Then the family moved to Pennsylvania and two long trips followed to Florida.
When Klaus was three and half years old his parents fulfilled their dream of buying a sailing yacht (his brother Hannes was two years younger and his youngest brother Florian was not yet born). For the next five years the family lived on board the Kajen .
They sailed from Portugal via Spain and Gibraltar into the Mediterranean and to Morocco, Canary Islands, down the West Coast of Africa to Dakar, Senegal, and Gambia, crossing the Atlantic from Dakar to Martinique and the lesser Antilles.
The first kindergarten and school Klaus attended were in Grand Canary and Tenerife. When he joined 'Svenska Scolan' in Los Cristianos, he was 5 years old and able to read and write. Most of the time he had private tuition from his mother (See Zettelwitz). He also learned many poems (including Goethe, 'Der Zauberlehrling' and Schiller, 'Der Handschuh') and he was always fond of poetry. When not yet six years old, he read his first novel (by Enid Blyton) - he could not wait for the nightly reading hour - and since then never stopped devouring books.
In 1976 the family moved to Germany and Austria and in 1981 they immigrated from Germany to South Africa: Stellenbosch.
At the age of 15, Klaus was bitten by the computer bug. A year later he wrote a text book on a computer language (Basic).
Klaus matriculated from Paul Roos Gymnasium in 1985. He studied Physics and Computer Sciences at the Universities of Stellenbosch and Berlin and Geography at the University of Erlangen.
In 1990 Klaus and his brother Hannes founded their own computer programming company to work freelance on many projects. Read more
The Proteus Team: Together with his father and brothers, Klaus - as the main programmer - created a proton therapy planning program, which remained for many years the most advanced program of its kind.
After a year in California, Klaus joined an IT company in Munich, Germany, which - both town and work - he enjoyed very much.
In 2003 it was discovered that Klaus had a tumor of the brain.
Klaus and Susanne are delighted parents of Ronja, born in April 2006.
In 2008 Klaus was married to Maggie Fang Wan, who is a student of applied mathematics, working on her Master's thesis.
Klaus died on 30 April 2013 in Munich. In memoriam
