Jean Rudolf von Salis

Jean Rudolf von Salis (12 December 1901 – 14 July 1996) was a Swiss historian. He gained prominence with his weekly "Weltchronik" (English: ''world chronicle'') radio broadcasts from 1940 until 1947.

As von Salis never wrote English publications and his works were rarely translated, he is little known outside of the European historical sciences. Provided by Wikipedia
