The most influential figure in the 20th century

This is a question that is doing the rounds of most Indian B School interviews. People with come up with all sorts of answers to this. Some say Hitler, some say Saddam and there are others which say Gandhi. Now to me the influential means the ability to influence directly or indirectly, mentally or physically and openly or in guise, the lives of other individuals. Sadly for humanity the most influential events are always that result in trauma, bloodshed and displacement of millions. If that were the case, I would say that a young Serbian named Gavrilo Princip was the most influential person of the 20th century. He was the guy who pumped one bullet apiece into Archduke Francis Ferdinand and his wife Sophie. The murder precipitated into the First World War and that in turn led to rise of communism and fascism that ultimately led to another bloody global conflict in 1939. India's independence was the direct result of the second world war and Britains increasingly slipping grip on pre-war colonies. Apart from India, a host of new countries gained independence immediately after the second world war. The second world war led to the discovery of nuclear power and consequently the arms race among the world's two superpowers. It also led to the emergence of a baby boom in America that led to soaring industrial productivity. I could go on and on, but guess I got to stop now. So people, now you know who was the most influential person in the 20th century. Sadly, he died of TB in a dank prison cell at the age of 24.
