John Tandberg

from Wikipedia, the free encyclopedia

John Gudbrand Tandberg (born November 1, 1896 in Norderhov , Norway , † January 3, 1968 in Lund , Sweden ) was a Norwegian-Swedish physicist , chemist , author and humorist .

Life

His parents were the Norwegian farmer Gudbrand Tandberg († 1908) and the Swedish photographer Lina Jonn (* 1861; † December 25, 1896). After his mother died of heart failure shortly after his birth, he grew up with his aunts in Lund, in an unconventional environment. He studied at Lund University until 1923 . Around 1922 he had worked with Carl Munters and Baltzar von Platen on the development of the first diffusion absorption refrigerator . In the summer of 1925 he married Greta Maria Cecilia Böös, with whom he had two sons: Erik Gudbrand Tandberg (* 1929) and Olof Gudbrand Tandberg (* 1932).

Tandberg's grave in Lund

He became a scientific advisor to Axel Leonard Wenner-Gren . From 1925 until his retirement in 1962 he worked in the laboratory of Wenner-Gren's company Electrolux in Stockholm. In 1927 he was appointed head of the Electrolux research laboratory.

Even William Prout († 1850) had suggested that the elements of hydrogen atoms are composed. After the First World War , the USA stopped supplying Germany with helium for the airships. In October 1926 Fritz Paneth and Kurt Peters published the article on the conversion of hydrogen into helium . (see Cold Fusion ) Based on this, Tandberg applied for a patent in February 1927 for a method for producing helium by electrolysis. At the time, the application was rejected on the grounds that the description was incomplete. Tandberg then continued working on his idea.

In 1937 he wrote his doctoral thesis The absorption of hard x-rays as studied by means of nuclear reactions and artificial radioactivity . His dissertation was published in 1937 at Uppsala University. His further research focused on X-ray and gamma radiation, in addition, he was also considered an expert in the field of corrosion. In total, he produced more than a hundred scientific papers. He had been a member of the Royal Swedish Academy of Engineering since 1942
