However, Strauss's mother encouraged him to perform public or humanitarian service. It was 1917; World War I was continuing to devastate parts of Europe and Herbert Hoover had become a symbol of humanitarian altruism by way of heading the Commission for Relief in Belgium. Accordingly, Strauss took the train to Washington, D.C., and talked his way into serving without pay as an assistant to Hoover. (Strauss and his biographer differ on whether this happened in February or May 1917, but the latter seems more likely.)
