What was Sir John Herschel famous for?
An accomplished chemist, Herschel discovered the action of hyposulfite of soda on otherwise insoluble silver salts in 1819, which led to the use of “hypo” as a fixing agent in photography. In 1839, independently of William Henry Fox Talbot, Herschel also invented a photographic process using sensitized paper.
What was William Herschel theory?
In 1785 he developed a cosmogony—a theory concerning the origin of the universe: the stars originally were scattered throughout infinite space, in which attractive forces gradually organized them into even more fragmented and tightly packed clusters.
What did William Herschel do for forensic science?
William James Herschel is considered one of the first Europeans to recognize the value of fingerprints for identification purposes. He began using fingerprints and handprints, instead of signatures, in his work as a magistrate in colonial India in the 1850s and 1860s.
What was the most important discovery made by William Herschel?
He made two preliminary telescopic surveys of the heavens. Then, in 1781, during his third and most complete survey of the night sky, William came upon an object that he realized was not an ordinary star. It proved to be the planet Uranus, the first planet to be discovered since prehistoric times.
Who discovered Pluto?
After Clyde Tombaugh discovered Pluto with the 13” Lawrence Lowell Telescope, he continued searching for other planets until 1942, covering about 75% of the sky. The telescope was subsequently used to study asteroids and comets and search for small natural satellites of Earth and the Moon.
What are the contribution of William Herschel in fingerprint?
Having conducted his own specific study, in 1880 he sent a letter to the famous naturalist Charles Darwin, suggesting that fingerprints were unique, classifiable and permanent. That same year Herschel became the first person to publish a paper in a scientific magazine on the use of fingerprints to identify individuals.
Who coined the word photography?
The word photograph was coined in 1839 by Sir John Herschel and is based on the Greek word ‘phos’, meaning ‘light’, and ‘graphê’, meaning ‘drawing’ – so ‘drawing with light.
What did William Herschel contribute to the science of light?
He found the first solid evidence that light and infrared are the same quantity that we know today to be electromagnetic radiation. Through a series of simple experiments, Herschel found the first piece in one of the great puzzles of physics that took another century to solve.
Who is the father of solar system theory?
Nicolaus Copernicus was a Polish astronomer and mathematician known as the father of modern astronomy. He was the first European scientist to propose that Earth and other planets revolve around the sun, the heliocentric theory of the solar system.
Who gave the double star theory?
J. C. Kapteyn’s double-drift theory of star motions? It explains why the two systems travelling in opposite directions should be of equal composition and proportions, but it necessitates that in the region of the sky opposite to that in which the double drift has been observed the drift should be simple.
Who discovered star evolution?
Two astronomers of the early 20th Century, Ejnar Hertzsprung and Henry Norris Russell, discovered an important observational means of comparing different stars with one another.
Who is the known Father of forensic Toxicology?
Mathieu Joseph Bonaventure Orfila (1787–1853), often called the “Father of Toxicology,” was the first great 19th-century exponent of forensic medicine. Orfila worked to make chemical analysis a routine part of forensic medicine, and made studies of asphyxiation, the decomposition of bodies, and exhumation.
Who discovered fingerprints?
The pioneer in fingerprint identification was Sir Francis Galton, an anthropologist by training, who was the first to show scientifically how fingerprints could be used to identify individuals. Beginning in the 1880s, Galton (a cousin of Charles Darwin) studied fingerprints to seek out hereditary traits.
Who was the first forensic?
James Marsh was the first to apply this new science to the art of forensics. He was called by the prosecution in a murder trial to give evidence as a chemist in 1832.
What is the most famous discovery of all time?
Without the discovery of DNA, we wouldn’t have all the ground-breaking studies going on right now in genome mapping and sequencing, so for that reason, DNA has to be my number one scientific discovery of all time.
Who discovered color temperature?
Herschel thought that the colors themselves might be of varying temperatures, so he devised a clever experiment to investigate his hypothesis. He directed sunlight through a glass prism to create a spectrum (the rainbow created when light is divided into its colors) and then measured the temperature of each color.

Did William Herschel Discover the Milky Way?
Abstract: In 1785 astronomer William Herschel mapped out the shape of the Milky Way star system using measurements he called “star-‐gages.” Herschel’s star-‐gage method is described in detail, with particular attention given to the assumptions on which the method is based.
