Quick Reference

      Background

      The Wizard of Menlo Park says that he hasn’t finished inventing the megaphone and cannot say when he will because he is “busily engaged on the electric light.”

      In a marvelous coincidence, on October 22, 1879, a bulb with a fragile filament of carbonized thread glowed at Menlo Park for the very first time.

      Mrs[.] Stroud

      Dear Madame

      Your favor of the 19th was duly rec'd -  The megaphone is not yet completed and I am quite unable to say when it will be as at present I am busily engaged on the Electric light.

      Very Truly

      T. A. Edison
