When was the fluorescent lamp invented?
- 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."

How did Alexander Graham Bell inspire you?
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.
What disability did Alexander Graham Bell have?
He was deaf.
ALEXANDER GRAHAM BELL WAS NOT DEAF!!! His mother and his wife Mabel Hubbard were, But Alexander Graham Bell was not! His motive for even starting to experiment with hearing was to learn more about the deafness.
Who are some notable Filipino inventors with pictures?
- 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.
What were the first words Alexander Graham Bell spoke into the telephone?
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."

Who is a famous Jamaican scientist?
5 Jamaican scientists
- Dr. Thomas Lecky acquired international fame for his work in animal breeding, having developed world famous Jamaican, and indeed tropically adapted, breeds of cattle by using the gene transfer and progeny testing techniques.

What Alexander bell's education?
As a young child, Bell, like his brothers, received his early schooling at home from his father. At an early age, however, he was enrolled at the Royal High School, Edinburgh, Scotland, which he left at age 15, completing only the first four forms. His school record was undistinguished, marked by absenteeism and lacklustre grades. His main interest remained in the sciences, especially biology, while he treated other school subjects with indifference, to the dismay of his demanding father. Upon leaving school, Bell travelled to London to live with his grandfather, Alexander Bell. During the year he spent with his grandfather, a love of learning was born, with long hours spent in serious discussion and study. The elder Bell took great efforts to have his young pupil learn to speak clearly and with conviction, the attributes that his pupil would need to become a teacher himself. At age 16, Bell secured a position as a "pupil-teacher" of elocution and music, in Weston House Academy, at Elgin, Moray, Scotland. Although he was enrolled as a student in Latin and Greek, he instructed classes himself in return for board and £10 per session. The following year, he attended the University of Edinburgh; joining his older brother Melville who had enrolled there the previous year. (Wikipedia)

Was Alexander Bell's wife deaf?
She was not deaf at birth and learned to speak before she became hard-of-hearing, not truly deaf, from an illness as a young girl. Many authorities attribute her abilities to speech read, speak, and even sing songs because of this early ability. Also, the ease at which she learned these skills may have contributed to Alexander Bell's belief that all deaf people could learn to speech read and speak.
