I want to know the answer to the following question:
Thomas Edison and what other scientist were already asked to work on a better telegraph?
All the background I'm provided with is that "When Bell mentioned to Gardiner Hubbard and Thomas Sanders that he was working on a method of sending multiple tones on a telegraph wire using a multi-reed device, the two wealthy patrons began to financially support Bell's experiments.". Is that enough to answer the question?
Answer: no
