William Manchester in volume two of his Churchill biography, “Winston Spencer Churchill: Alone, 1932-1940”. He describes Churchill as a “sensible, if unorthodox drinker”. Churchill would imbibe throughout the course of the day, but his family never saw him drunk and he frequently derided men seen intoxicated in public. He himself said “I have taken more out of alcohol than alcohol has taken out of me.” According to Manchester, Churchill promoted the idea of him being a hard-drinking man in part to give him a manly image and offset his frequently getting emotional and crying in public.
