Except, Oppenheimer’s rich father happened to be visiting that week. He begged Cambridge to spare his precious, genius son. So, Oppenheimer got off with mere probation." https://www.sciencehistory.org/stories/disappearing-pod/the-real-tragedy-of-robert-oppenheimer https://www.sciencehistory.org/stories/disappearing-pod/the-...
