He might be retired now, but Richard Evans used to be a professor at Cambridge. He was no ivory tower academic, but used to do lectures open to the public. He's also written numerous books about Hitler and his rise to power. He and another historian, Ian Kershaw, destroyed the myth that Germans were all evil supporters of Nazism, which was the prevalent view immediately after WW2. By laborious study of original sources and interviews, they showed that Germans were just ordinary people with normal concerns about their country, their lives, their future, etc. - just like people today.
