Listers:

I got my inventions, not my inventors, crossed.  It was Edison, not A. Bell:
Thomas Edison, the brilliant inventor whose accomplishments include the light 
bulb, also spent years attempting to invent a device to communicate with the 
dead. Edison, whose parents were spiritualists, never fulfilled his dream of 
creating such a device. This little-known fact was first publicized in The 
American Magazine in October, 1920, in an article entitled, Edison Working to 
Communicate With The Next World. It is also documented in Sinclair Lewis’ 1951 
book, Mental Radio, which has a foreword written by Albert Einstein.

Sorry for the mis-statement.
