- Journalist and politician
Friedrich Adler, son of the Social Democratic Party leader Victor Adler, was the Party Secretary of the Austrian Social Democrats between 1911 and 1914. As an opponent of the war, he objected to the Social Democrat war policy and ultimately resigned from his position as Party Secretary. On 21 October 1916, Friedrich Adler assassinated the Austro-Hungarian Prime Minister Karl Graf Stürgkh, whom he regarded as being responsible for the continuation of the war. Adler was then sentenced to death, but reprieved by Emperor Karl and amnestied shortly before the end of the war.
