Did Alexander Graham Bell invent the telephone? Yes, he won the patent for it but it may not mean he was the inventor.
There's a Bell Museum in Nova Scotia, Canada. Much more space in that
museum is devoted to hydrofoil watercraft than the telephone!
A Canadian publication said that no one invented the telephone,
just that several inventors worked on the telephonic concept
at the same time, and Bell was the first one to hand in the
patent. See: Wikipdia - Telephones
