Telephone

Aeronautics

Hydrofoils

Bell begins work on Harmonic telegraph, and got support for his idea of telephone

Met Thomas Watson which allowed him to have the equipment necessary for experimenting

2 June 1875, Watson accidentally plucked one of the reeds and Bell, at the receiving end of the wire, heard the overtones of the reed; overtones that would be necessary for transmitting speech.

“Watson, come here I need you,” were the first words heard over the telephone. Bell had spilled liquid on the testing table.

Elisha Gray vs. Alexander Graham Bell
  • There is considerable debate about who arrived to the U.S. Patent Office First
  • Gray filled a caveat with the US Patent Office for a telephone design that used a water transmitter.
  • That same morning, Bell’s lawyer filed his patent application.
  • There is considerable debate about who arrived first.
  • Gray later challenged the validity of Bell's patent.

Competitors

Over a period of 18 years, the Bell Telephone Company faced over 600 lawsuits posing legal challenges concerning the rights to the telephone, but none was successful in establishing priority over the original Bell patent.

On 13 January 1887, the United States

Government moved to annul the patent issued to Bell. By the time the case surfaced, the patents were expired and the case was dropped by the US Attorney General.

Italian inventor Antonio Meucci also claimed to have created the first working model of a telephone in Italy in 1834.

Bell was a firm believer in EUGENICS
  • A widely held belief in the early 20th century that handicapped couples and couples in poverty should have no children.
  • Even possibly should be sterilized.
  • He observed that congenitally deaf parents are more likely to produce deaf children.
  • He suggested that couples in which both were deaf should not marry.
slide13

Toward the end of his life, Bell investigated heredity, beginning with deafs.

  • Invented an electromagnetic device called an induction balance and a telephone probe, a metal vaccum jacket that is breathable, and an audiometer.
  • Most of his effort, however, went towards the challenge of flight.
  • Bell spent the last decade of his life improving hydrofoil designs, and in 1919 he and Casey Baldwin built a hydrofoil that set a world water-speed record that was not broken until 1963
  • Bell died of diabetes on August 2, 1922, at his private estate, Beinn Bhreagh, Nova Scotia, at age 75.
