Long before Clark Griswold connected 250 strands of lights to decorate his house for Christmas, he must thank Edward H. Johnson. Thomas Edison hired Johnson in 1871 and by the time he founded the Edison Electric Light Company, Johnson was named as vice president. One of Johnson's favorite holidays was Christmas and in 1882, he put his electrical ingenuity to work. He hand-wired a string of 80 red, white, and blue bulbs the size of walnuts to his Christmas tree. Additional lights decorated his ceiling.
