Photographer Philippe Halsman photographed many of the famous and powerful people of his day. He also asked these subjects to do something strange. Here is what he says about it:
"Starting in the early 1950s I asked every famous or important person I photographed to jump for me. I was motivated by a genuine curiosity. After all, life has taught us to control and disguise our facial expressions, but it has not taught us to control our jumps. I wanted to see famous people reveal in a jump their ambition or their lack of it, their self-importance or their insecurity, and many other traits."
Here are some examples from his series of jumps:
