Alexander Graham Bell

Alexander Graham Bell was born to Alexander Melville Bell and Eliza Grace Symonds Bell. His family was known for their work on speech and elocution.

Bell begins his career as a teacher of speech and elocution at Weston House Academy in Elgin, Scotland, where he also continues his studies.

Bell and his family move to Brantford, Ontario, Canada, to escape poor health conditions and the tuberculosis that had claimed the lives of his brothers.

Bell opens his own school for the deaf in Boston, Massachusetts, where he teaches visible speech, a technique to help the deaf learn to speak.

Bell conceives the idea of the telephone while experimenting with harmonic telegraphy, a method of sending multiple telegraph messages simultaneously over a single wire.

Bell patents the telephone on March 7, 1876, and demonstrates it at the Centennial Exhibition in Philadelphia, where it garners international attention.

Bell marries Mabel Hubbard, one of his former students who was deaf. They go on to have four children together, two of whom survive to adulthood.

Bell founds the Volta Laboratory in Washington, D.C., where he and his associates conduct research on sound and hearing, leading to numerous inventions and innovations.

Bell becomes a founding member and later the second president of the National Geographic Society, contributing to its growth and influence in scientific exploration.

Alexander Graham Bell dies at his estate, Beinn Bhreagh, in Nova Scotia, Canada, leaving behind a legacy of innovation and contributions to science and communication.
