Bell’s father, grandfather, and brother has all been associated with work on speech, and both his mother and wife were deaf, profoundly influencing Bell's life's work. At the age of twenty three, Alexander Graham Bell moved to Canada with his parents. His research on hearing and speech at Boston University further led him to experiences with hearing devices which culminated in Bell being awarded the first U.S. patent for the telephone in 1876.
A year later after he moved in with his parents, he started teaching at the Boston School for Deaf Mutes which he established in Boston, Massachusetts.
