Walter William Marseille (born 1901) was a German-American psychoanalyst and graphologist. In 1948 he corresponded with Albert Einstein and Bertrand Russell, advocating world government. Life Walter Marseille was the son of Gustav Marseille, a leader in the progressive education movement. He studied psychology, mathematics, history, and philosophy at the Universities of Heidelberg, Freiburg, and Munich. In 1926 he took a doctorate under Martin Heidegger at Marburg University. Further information is given by his friend Karl Löwith. From 1928 to 1933 Marseille followed the workshops (Arbeitsgemeinschaft) of Heinrich Jacoby in Berlin; his address was Dernburgstr. 34, Charlottenburg (Berlin). He later claimed to have broken with Heidegger in 1932 over Heidegger's refusal to condemn Nazism. Löwith tells us that Marseille left Germany in 1933, went to Vienna where he married a woman of Jewish origin, and then emigrated to the United States. He trained as a psychoanalyst at the Berlin Psychoanalytic Institute and the Vienna Psychoanalytic Society, and took Ruth Mack Brunswick as his training analyst. Marseille was hired by Paul Lazarsfeld in 1940 to analyse the handwriting of mail received by US Senators during the debate on the conscription bill, and developed an index for the cultural rating of handwriting. In April 1948 Marseille sent a paper, "A Method to Enforce World Peace", to both Bertrand Russell and Albert Einstein. A copy of the paper is in the Einstein archives along with correspondence with Einstein about it. See Einstein on Peace (1960), edited by Otto Nathan.

I believe that this characterisation of the psychological state of affairs is not justified. Now to your proposal. We agree on the following: only World Government can produce security. Where we differ is in the thesis that we must compel Russia to join [a World Government] before it re-arms and can
