Dr. Walter Bishop
Walter is an eccentric Scientist who, along with his lab partner, Dr. Bell, worked on secret government advanced technologies in areas we call "Fringe" science (his son calls them non-science). These wonderful things he worked on included means to make skin transparent, teleport people to different places and times, talk to the dead, provided they weren't dead longer than six hours and even meld two minds.
