Join Lead Site Historian, Eric Kahler, as he shares his knowledge about Edison and his accomplishments within the field of science. By the end of his life, Edison had succeeded in the development of a practical method of laboratory testing and production. Much of the processes he patented within the Edison Botanic Research Corporation are still used today including his work on hybridization of goldrenrod in an effort to increase rubber yields and the idea of the reuse and recycling of solvents.
