b'WINSTON CHURCHILL Winston Churchill, prime minister of Great Britain, who helped lead the world to defeat Hitler in WWII, wrote of suffering from black dog, his term for severe and serious depression. Churchill likely experienced bipolar disorder, because, according to his close friend Lord Beaverbrook, Churchill was always either at the top of the wheel of confidence or at the bottom of an intense depression. Through sheer determination and knowing that a nation and world depended on his efforts, Churchill led Britain in its part to defeat Nazism. Academic Concerns104'
