Helen Keller - Born in 1880 and blind and deaf by the age of two, Helen Keller became an internationally known writer, educator, activist, and spokesperson for people with disabilities. She met the already-famous inventor Alexander Graham Bell when she was seven, and they maintained a close friendship until his death several decades later. Having grown up with a deaf mother, Bell had a personal interest in helping the deaf to communicate. Keller became the first deaf and blind person to graduate from Radcliffe College, now part of Harvard University, with her tuition paid for with a trust fund established by Bell.
Alexander Graham Bell was born in Edinburgh, Scotland, on March 3, 1847. Before becoming an inventor, Bell had a keen interest in helping the deaf. His father and grandfather were expert elocutionists; his mother, a pianist, began to lose her hearing when Bell was around 12 years old. While studying for his college degree, he assisted his father teaching at a school for the deaf in London. However, before he finished college, both of his brothers died of tuberculosis, and the family moved to Canada in hopes of finding a healthier environment.
In April 1870, Bell moved to Boston to train teachers to teach deaf students how to speak at the Boston School for Deaf Mutes. Successful, he repeated the program for teachers at two other schools for the deaf. In October 1872, Bell opened his own school in Boston and worked as a private tutor for deaf students. He tutored Helen Keller, becoming her lifelong friend and champion.
Late at night, after teaching, Bell worked to invent a harmonic telegraph--a tool that could send multiple messages at once over a single wire. In autumn 1873, he left teaching to solely pursue experiments and inventions. While struggling with the harmonic telegraph, Bell contemplated sending the sound of the human voice, instead of text, over the wire. In 1874, he hired an electrical designer, Thomas Watson, to help him with his sound transmitting experiments.
After about a year of further experimentation, Bell applied for a patent to protect his idea of sending vocal sounds electrically through wires. The patent, number 174,465, was issued to Bell on March 7, 1876. Three days later, Bell called over the wire to his assistant, “Mr. Watson, come here; I want you.” Watson clearly heard the entire sentence. The telephone was born.
In June 1877, Bell created the Bell Telephone Company; within a decade, more than 150,000 people in the United States owned phones. Just days after he established the Bell Telephone Company, he married one of his former deaf students, Mabel Hubbard. They split their time between Washington, DC, and Nova Scotia, Canada.
Continuing his passion for voice transmissions, in 1880, Bell invented the photophone--an instrument that transmitted speech on a beam of light. Bell considered the photophone an even greater achievement than the telephone; indeed, it proved to be a precursor to modern-day fiber-optic communication systems.
In many ways, Bell was ahead of his time. In the 1890s, he experimented with airplanes, helping to create the first powered flying machine in Canada -- the Silver Dart. At his Nova Scotia boatyard, he worked with boat designers to build HD-4, a hydrofoil, that in 1919 took the World Marine Speed Record and held it for two decades. In 1881, when President James Garfield was shot, he even helped to invent an early metal detector to try to find the bullet in his body.
In 1887, Bell founded the Volta Bureau. Helen Keller, Bell’s former student, led the groundbreaking ceremony. The Bureau’s mission was to increase and spread knowledge about the deaf. Now called the Alexander Graham Bell Association for the Deaf and Hard of Hearing, it has become a world-renowned centre of education, research, and advocacy for the deaf community.
Bell died on Aug. 2, 1922, at his home Nova Scotia. At the end of his funeral, all the phones in North America went silent for a minute in honor of his life.
