Thomas Alva Edison (1847-1931), American inventor. Despite receiving little formal education, Edison filed over 1000 patents during his life, more than any other inventor. His first commercial success came with a stock ticker for a Wall Street firm. This provided him with the funds to set up his own research company. Here he devised the phonograph (for recording sound) and the light bulb, amongst other inventions. During work on the light bulb he discovered the Edison Effect a current flows from a hot filament to an electrode, but not the other way around. This formed the basis of the ther- mionic valve. He was awarded the John Fritz medal.
About the Artist - Science, Industry & Business Librarynew York Public Library
Science Photo Library was founded in 1981 by Michael Marten, one of the authors of "Worlds Within Worlds", a book exploring different ways to observe the universe - from electron micrographs, to images of earthrise taken from the Apollo spacecraft. When Marten started receiving requests for the beautiful images in the book, he had an idea of setting up Science Photo Library.
Since then, Science Photo Library has continued to work alongside world acclaimed photographers and the leading science and medical experts to provide a central source of the best science and specialist imagery available. Although the collection started with scientific images, it has grown to encompass all aspects of science and their impact on everyday life.
