Jesse Fuller

Jesse Fuller wrote The Monkey and the Engineer. A song covered by many musicians, including the Grateful Dead, and more recently Dave Rawlings. He invented that contraption next to him named the "fotdella". 

From Wikipedia: The name "fotdella" was given to the instrument by Fuller's wife, who took to calling it a "foot-diller" (as in the then-current expression, "killer-diller", meaning exceedingly good); later, it became shortened to just fotdella.

Here he is (shoeless) playing all that stuff.
