Wolfgang Döblin, son of the famous writer Alfred Döblin and a talented mathematical genius, obtained French citizenship while in exile and was mobilized as a soldier during the Franco-German War in 1939. Despite the extreme conditions at the front, he worked on his theories of random motion, particularly "memoryless random processes." At only 25 years of age, he took his own life to avoid capture by the Wehrmacht, but left behind significant works in probability theory that underscore his influence on modern mathematics.
