Alexander Graham Bell

Yes Alexander Graham Bell was famous, because in 1876, at the age of 29 Mr. Graham Bell invented his telephone. In 1877, he formed the Bell Telephone Company.

Hope that helps. (:

it happend about 1777 and ended 1789

No, actually, this isn't.... It should be...... The lightbulb was invented by Thomas Edison in 1879. Thomas was born on February 11, 1847, and he died on October 18, 1931. No; a good paragraph needs more information relevant to the topic--the first sentence--, not to mention correct spelling, grammar, punctuation, etc. I agree with the first guy plus that is like, a 23 word paragraph. WAY 2 SHORT, sorry I agree with everyone but that 2nd guy. Much, much, to short.

he invented the telephone

Alexander Graham Bell is well known for the invention of practical Phone. The range of Bell's inventive genius is represented only in part by the 18 patents granted in his name alone and the 12 he shared with his collaborators. These included 14 for the telephone and telegraph, four for the Photophone, one for the phonograph, five for aerial vehicles, four for "hydroairplanes" and two for selenium cells. Bell's inventions spanned a wide range of interests and included a metal jacket to assist in breathing, the audiometer to detect minor hearing problems, a device to locate icebergs, investigations on how to separate salt from seawater, and work on finding alternative fuels.

Bell worked extensively in medical research and invented techniques for teaching speech to the deaf. During his Volta Laboratory period, Bell and his associates considered impressing a magnetic field on a record as a means of reproducing sound. Although the trio briefly experimented with the concept, they could not develop a workable prototype. They abandoned the idea, never realizing they had glimpsed a basic principle which would one day find its application in the tape recorder, the hard disc and floppy disc drive and other magnetic media.

Bell's own home used a primitive form of air conditioning, in which fans blew currents of air across great blocks of ice. He also anticipated modern concerns with fuel shortages and industrial pollution. Methane gas, he reasoned, could be produced from the waste of farms and factories. At his Canadian estate in Nova Scotia, he experimented with composting toilets and devices to capture water from the atmosphere. In a magazine interview published shortly before his death, he reflected on the possibility of using solar panels to heat houses.

Alexander Graham Bell worked with Thomas Watson on the telephone. The telephone was Alexander Graham Bell's idea.

Alexander Graham Bell's parents were Alexander Melville Bell and Eliza Grace Symonds. They were both born in Edinburgh, Scotland, as was Alexander Graham Bell himself.

Yes, but they died of Tuberculosis a type of lung disease.

Because he wanted people to hear properly!

Bell's daughter was deaf. Bell was an inventor and wanted to know more about how people hear. Bell also made several other advancements in the knowledge of human hearing because he wanted to help his daughter,

The Audiometer was made after performing several experiments with the loudness of sounds and how humans hear things.

The meter he made is a way of measuring how well someone can hear compared to what an average person can hear.

Like Feet and Meters are used for measuring the length of objects or the distance between objects, the measurement called a Bell was named to measure the loudness of sounds that humans hear.

More commonly the measurement is called a 'Deci Bell' abbreviated dB which is 1/10th of a Bell.

they died from tuberculosis. they started to die when they moved to London with his family.

Yes, Alexander Graham Bell who was the inventor of the telephone got married. He got married to a woman named Mabel Hubbard on July 11, 1877. She was one of his former students and the daughter of his first financial backer.

Alexander Graham Bell had a brother named Melville and a brother named Edward. Bell is most well-known for inventing the telephone.

cans were invented 45 years ago!!!

no, but he did invent the telephone.

- Heinrich Geissler invented the mercury lamp, the first stage.

- Julius Plücker, William Crookes, Hermann Sprengel, Alexandre Edmond Becquereland others worked on the idea coming up with an improved theory and better methods to make them.

- George G. Stokes created the version we know today when he noted that ultraviolet light caused fluorspar to fluoresce.

- Georges Claude invented the neon lamp, a refinement.

- George E. Inman built a prototype fluorescent lamp in 1934 at General Electric's Nela Park (Ohio) engineering laboratory. So he invented the fluroescent bulbs we use today.

- "General Electric controlled what it regarded as the key patents covering fluorescent lighting, including the patents originally issued to Cooper-Hewitt, Moore, and Küch."

According to Wikipedia: http://en.wikipedia.org/wiki/Fluorescent…

"The history of the fluorescent lamp begins with early research into electrical phenomena. By the beginning of the 18th century, experimenters had observed a radiant glow emanating from partially evacuated glass vessels through which an electrical current passed. Little more could be done with this phenomenon until 1856 when a German glassblower named Heinrich Geissler (1815-1879) created a mercury vacuum pump that evacuated a glass tube to an extent not previously possible. When an electrical current passed through a Geissler tube, a strong green glow on the walls of the tube at the cathode end could be observed.

Because it produced some beautiful light effects, the Geissler tube was a popular source of amusement. More important, however, was its contribution to scientific research. One of the first scientists to experiment with a Geissler tube was Julius Plücker (1801-1868) who systematically described in 1858 the luminescent effects that occurred in a Geissler tube. He also made the important observation that the glow in the tube shifted position when in proximity to an electromagnetic field.

Inquiries that began with the Geissler tube continued as even better vacuums were produced. The most famous was the evacuated tube used for scientific research by William Crookes (1832-1919). That tube was evacuated by the highly effective mercury vacuum pump created by Hermann Sprengel (1834-1906). Research conducted by Crookes and others ultimately led to the discovery of the electron in 1897 by J. J. Thomson (1856-1940). But the Crookes tube, as it came to be known, produced little light because the vacuum in it was too good and thus lacked the trace amounts of gas that are needed for electrically stimulated luminescence.

Alexandre Edmond Becquerel observed in 1859 that certain substances gave off light when they were placed in a Geissler tube. He went on to apply thin coatings of luminescent materials to the surfaces of these tubes. Fluorescence occurred, but the tubes were very inefficient and had a short operating life. A few years earlier another scientist, George G. Stokes (1819-1903), had noted that ultraviolet light caused fluorspar to fluoresce, a property that would become critically important for the development of fluorescent lights many decades later."

yes he had four children.Yes but 2 of them died during infancy.

Alexander Grahm bell inspires me because he belived in communication. He always wanted to improve the way people communicate he improved the multiple telegraph and invented the telephone. if it wasnt for him we probably wouldn't have cell phones. so thank him for everything he has done for us.

• Fe del Mundo, the first Asian to have entered the prestigious Harvard University's School of Medicine, is also credited for her studies that led to the invention of incubator and jaundice relieving device. Del Mundo, an International Pediatric Association (IPA) awardee, is an alumna of the University of the Philippines (UP) College of Medicine. Since 1941, she has contributed more than 100 articles to medical journals in the U.S., Philippines and India. In 1966, she received the Elizabeth Blackwell Award, for her "outstanding service to mankind". In 1977, she was bestowed the Ramon Magsaysay Award for outstanding public service.

The first words Alexander Graham Bell spoke on the phone was, "Mr. Watson, come here. I want to see you."
Alexander Graham Bell's notebook entry of 10 March 1876 describes his successful experiment with the telephone. Speaking through the instrument to his assistant, Thomas A. Watson, in the next room, Bell utters these famous first words, "Mr. Watson -- come here -- I want to see you."
