Abandoning his medical studies, Schnitzler trained for a business career in Cologne and embarked on a commercial apprenticeship. In 1939, he became the owner of a delivery business. When the Second World War broke out in 1939, Schnitzler was drafted into the Wehrmacht, but was taken prisoner by British forces in 1944, following the Battle of Normandy. After his capture, he began to work for the British Ministry of Information and for the German-language service of the BBC, where his talents as a broadcaster were soon recognised. After his release in 1945, he returned to the British Zone of Allied occupied Germany and became an employee of the British controlled radio station Nordwestdeutscher Rundfunk in Hamburg. He was transferred to their Cologne studios on 1 January 1946, where he was assigned to the post of Associate Director and Head of the Politics Department. His political bias soon became apparent to his superiors and he was removed from his position in Cologne and returned to the NWDR's Hamburg offices until his eventual dismissal in 1947, after being accused of spreading communist propaganda.
Career in the GDR
Schnitzler moved to the Soviet occupation zone, where he worked for the Berliner Rundfunk and the Deutschlandsender program of the Rundfunk der DDR. He joined the Socialist Unity Party in 1948. During the 1950s, he contributed to a number of smaller television shows before the first broadcast of Der Schwarze Kanal on 21 March 1960. The programme was originally designed as East Germany's answer to the short-lived West German anti-Communist programme Die Rote Optik. From 1969 on, though, Schnitzler's main antagonist in the west was Gerhard Löwenthal's ZDF Magazin, which focused on human rights issues in East Germany. As host of Der Schwarze Kanal, which ran for 20 minutes every Monday night, Schnitzler edited together extracts of Westerntelevision footage and recorded caustic, virulently anti-Western commentary over it. The show was particularly derisive towards West Germany and what Schnitzler perceived as Western imperialism across the world. His vitriolic style earned him the nickname Sudel-Ede – roughly, "Besmirching Eddie". Von Schnitzler joined the central committee of the Society for German–Soviet Friendship in 1978. In that same year, he also became a professor at the University of Film and Television in Potsdam-Babelsberg. He became known among other communist politicians as a hardliner.
Post-GDR career and death
In the course of the 1989 Wende in East Germany, Der Schwarze Kanal was canceled. Schnitzler pre-empted his exclusion from the reformed communist Party of Democratic Socialism by quitting and joining the German Communist Party. In Schnitzler's late career, he published several articles in the satirical magazine Titanic and continued to work with the small German Communist Party. In 1999, Schnitzler appeared on the national German television talk show Ich stelle mich. Schnitzler maintained that his show was truthful, and continued to support several GDR policies. Schnitzler would retire to Zeuthen, where he died of pneumonia on 20 September 2001. Interviews with von Schnitzler can be found in Stasiland by Anna Funder and The Saddled Cow by Anne McElvoy.
