Between and , Bell spent long days and nights trying to perfect the harmonic telegraph. But during his experiments, he became interested in another idea, transmitting the human voice over wires. Through and , Bell and Watson labored on both the harmonic telegraph and a voice transmitting device.
For now the concept was protected, but the device still had to be developed. In , Bell and Watson were finally successful. Watson, come here — I want to see you. With this success, Bell began to promote the telephone in a series of public demonstrations. The Bell Telephone Company was organized on July 9, In January , Bell was invited to make the first transcontinental phone call. By all accounts, Bell was not a sharp businessman and by began to turn business matters over to Hubbard and others so he could pursue a wide range of inventions and intellectual pursuits.
Later in his life, Bell became fascinated with flight and began exploring the possibilities for flying machines and devices, starting with the tetrahedral kite in s.
The group developed several flying machines, including the Silver Dart. The Silver Dart was the first powered aircraft flown in Canada. Bell later worked on hydrofoils and set a world speed record for this type of boat. After their wedding, Alexander and Mable traveled to Europe demonstrating the telephone. Others claimed they had invented the telephone or had conceived of the idea before Bell. Bell filed his patent for his version of the telephone on February 14, Later that same day, a lawyer working for Elisha Gray submitted a caveat, a type of announcement of an invention, for the telephone on his behalf.
As he wrote to his parents in , Bell had been aware of his competitor's efforts and felt enormous pressure to finish his own design. Gray and myself who shall complete our apparatus first," he observed, according to Charlotte Gray's Reluctant Genius: Alexander Graham Bell and the Passion for Invention.
In March , Bell received the telephone patent. Competitor Western Union hired other inventors, including Gray, to develop their own phone system, which led to a legal fight between the two businesses. Over the years, Bell vigorously defended his telephone patent in a number of other lawsuits.
Bell created the photophone, which used light to transmit sound. Bell considered it to be one of his greatest inventions. He also used his gift for inventing to solve problems. After the death of his infant son in , Bell made a metal vacuum jacket to help with breathing. This idea influenced the design of the iron lung device used to aid polio patients in the s. When an assassin shot President James Garfield in , Bell was asked to help the ailing leader.
He came up with an electromagnetic machine to detect where the bullet was lodged in Garfield's body. In spite of gaining fame as the inventor of the telephone, Bell continued his lifelong work to help the hearing impaired. In , Captain Arthur Keller traveled from Alabama to meet with Bell in order to seek help for his 6-year-old daughter, Helen, who had become blind and mute at the age of 19 months, possibly from scarlet fever. Bell began experimenting in aviation in the s, even developing giant manned tetrahedral kites.
His dreams of airplanes that could take off from water led him to work on the designs of winged hydrofoil boats that skipped across the water surface at high speeds.
The HD-4 model on which he collaborated reached a speed of more than 70 miles per hour during a test on a lake in Nova Scotia, a world water-speed record that stood for more than a decade.
The headstone of Alexander Graham Bell photographed in Bell died at his summer home in Nova Scotia on August 2, Two days later all telephone service in the United States and Canada was suspended for a full minute at the precise moment when Bell was lowered into his grave.
