Tesla was an avid and professional experimenter throughout his life. His curiosity was of such an intense nature that he was able to plumb the myster ies of an electrical peculiarity with no regard for his own comfort. Whereas Edison would work and sleep for a few hours on the floor, Tesla would never sleep until he had achieved success in an experimental venture. This mara thon could last for days. He was once observed to work through a seventy-two hour period without fatigue. His technicians were in awe of him.
