Handbalancing goes back a long way although the man that took it to a whole new level was Professor Paulinetti. He perfected many of the most difficult hand balancing feats — and was the first man to accomplish the incredibly difficult one-arm planche. Professor Paulinetti was also the mentor to famed hand balancer Bob Jones. In fact, the image above once belonged to the personal collection of Bob Jones. On the back it is written that this photograph was taken in Italy around the year 1900.
