38. Winston Churchill

Winston Churchill was the prime minister of the United Kingdom during World War II and, along with Josef Stalin, Franklin Roosevelt, and Dwight Eisenhower, helped bring about the defeat of the German Third Reich. He conducted much of the war from his underground bunker and ordered blackouts of major cities to prevent the Nazi bombing raids from being able to target civilians. He also helped engineer the D-Day invasion of Normandy, which spelled the beginning of the end for the Nazis.
