Edison the scientist.
This year marks the 100th anniversary of Edison's invention of the electric lamp, one of many heralded accomplishments that brought him lasting fame.

His participation in the Draper Expedition to the solar eclipse of 1878, told here, offers a chance to evaluate the youthful Edison as an astronomer and infrared physicist.
