Coal mine rescue. 19th-century artwork of a coal mine rescue worker using breathing apparatus as he rescues a miner. This breathing apparatus was developed around 1865 by the mining engineer Benoit Rouquayrol. It was the first system that delivered air at the right pressure and on demand, which it did by using a valve system called a regulator. Air was breathed through the mouth from a pressurized supply on the rescue worker's back, and the nose was closed with a clip. Explosions caused by methane gas were one of the many dangers faced by 19th-century coal miners, along with the carbon dioxide produced from the burning methane. Engraving by P. Ferat and Hildibrand, published in Mines and Miners (L. Simonin, 1868).
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.
