Not many people know that Edison was a avid fisherman. He usually included some trout fishing in his infrequent vacations.

During one such trip to the west he was befriended by an Indian tribe.  They provided free room and board, as well as expert fishing guides for his stay.  On his first night he discovered that the only sanitary facility was an old-fashioned outhouse.  To make things worse it had no light even though the village had electricity in the homes.

As a thank-you gift for their kindnesses, Edison purchased the necessary materials and personally installed lighting in the Indians privvy.

He thus became the first person to wire a head for a reservation.
