  " On October 21, 1916, in the dining room of the Viennese hotel Meißl und Schadn, he shot the Minister-President of Austria Count Karl von Stürgkh with a pistol three times, killing him. For this act Adler was sentenced to death, a sentence which was commuted to 18 years imprisonment.

After the outbreak of the revolution of 1918 he was released and he played a significant role as leader of the Arbeiterräte (workers' councils) and as a member of the National Council of Austria. From the mid-1920s he was mainly active in the Socialist International, whose secretary-general he was to remain for over 15 years.

After the outbreak of the Second World War Adler fled to the United States. In 1946 he retired from politics and edited his father Victor's exchange of letters with August Bebel and Karl Kautsky. Adler died on January 2, 1960 in Zurich."

    "The first lecture will report on Einstein's close friendship with Friedrich Adler, an epistemologist, physicist, and activist who lived in the same house as Einstein during a crucial part of his early career, who corresponded later with Einstein extensively--and who killed the prime minister of the Austro-Hungarian Empire."

Comment does not looke like much credit to Einstein. (WPT).
