The following year he became a professor in speech and vocal physiology at Boston University. While teaching, he experimented with means of transmitting several telegraph messages simultaneously over a single wire and also with various devices to help the deaf learn to speak. While constantly engaged in scientific experiments, Bell crusaded tirelessly on behalf of the deaf, encouraging their integration into society with the help of lip-reading and other techniques. In 1890 he founded the Alexander Graham Bell Association for the Deaf. Alexander Graham Bell's role as a teacher for deaf individuals and the presence of his deaf wife and mother inspired him to develop his electrical speech machine, or telephone.
