Alfred Stettbacher

from Wikipedia, the free encyclopedia

Alfred Stettbacher (* 1888 ; † July 9, 1961 in Zurich ) was a Swiss explosives technician and co-editor of the Schweizerische Chemiker Zeitung .

Life

During his training as an engineer-chemist in 1912 at the ETH Zurich , he also came into contact with philosophy and music. At the University of Geneva, he obtained his doctorate in natural sciences from Amé Pictet with his thesis "Essai de synthesis de la morphidine".

He initially worked in the explosives industry in various locations in Germany. The fact that he was not always a comfortable subordinate "has not always made his professional career easier". Before the First World War he was temporarily in the Swiss Sprengstoffabrik AG (SSF) in Dottikon. In 1916 he invented nitropenta, with the highest explosive value of 193,000 at the time. Between 1913 and 1918 he corresponded with Pictet and in mid-May 1920 he was in correspondence with Wilhelm Ostwald and Otto Wiener .

In April 1921, the Schwamendingener started as "Assistant Second Class" at the Agricultural Research Institute Oerlikon , where he worked in a managerial position until his retirement, which he experienced at the age of 65. After that he made three major world trips to the USA, India and the Far East.

In numerous publications on ecclesiastical, social, economic and chemical problems, he commented on contemporary issues and was a fighter for law and justice. He was very critical of the modern welfare state, which in his view inhibits personal commitment. As a keen mountaineer, he was a member of the Swiss Alpine Club. The increasing motorization and the “tendency of the general public to be physically comfortable” annoyed him.
