Several people contributed pioneering work on the telephone in the late 1800s, including Innocenzo Manzetti, Antonio Meucci, Johann Philipp Reis, Elisha Gray, and Alexander Graham Bell. Bell is often credited as the inventor of the telephone, being granted a patent for it in 1876. His device allowed transmission of clear speech for the first time when he said "Mr. Watson, come here, I want to see you." Bell vacationed in Nova Scotia and it was his father who introduced the telephone to Canada.
