  Sir Frederick William Herschel - LoveToKnow 1911
SIR FREDERICK WILLIAM HERSCHEL (1738-1822), generally known as Sir William Herschel, English astronomer, was born at Hanover on the 15th of November 1738.
Herschel's earlier education was necessarily of a very limited character, chiefly owing to the warlike commotions of his country; but being at all times an indomitable student, he, by his own exertions, more than repaired this deficiency.
Herschel married, on the 8th of May 1788, the widow of Mr John Pitt, a wealthy London merchant, by whom he had un only son, John Frederick William.

 William Herschel
William Herschel (born: Friedrich Wilhelm Herschel, September 15, 1738 - August 25, 1822) was an astronomer and composer; who discovered Uranus (1781) and infrared radiation (c.
Herschel discovered infrared radiation by passing sunlight through a prism and holding a thermometer just beyond the red end of the visible spectrum.
The thermometer indicated a temperature increase and this led to Herschel's conclusion that there must be an invisible form of energy.

 Cool Cosmos
Herschel performed further experiments on what he called the "calorific rays" that existed beyond the red part of the spectrum and found that they were reflected, refracted, absorbed and transmitted just like visible light.
Herschel's experiment was important not only because it led to the discovery of infrared, but also because it was the first time that someone showed that there were forms of light that we cannot see with our eyes.
Herschel's original prism and mirror are on display at the National Museum of Science and Industry in London, England.

 William Herschel Summary
Herschel moved to Windsor, near the King's residence, and in due course was given the patronage for which he had long hoped--a salary for himself and his sister, upkeep for the telescope, and later a very large sum for a 40-foot telescope, the largest ever made before the mid-19th century.
William Herschel (1738-1822) was born in Hanover, Germany, and moved to England in 1757 to pursue a career as a musician.
Herschel was also assisted by his wife Mary, whom he married in 1788, and by his son John Frederick William Herschel (1792-1871) who continued his father's studies of nebulae and also became a pioneer in the development of photography.

 William Herschel
Herschel was born in Hanover, Germany, on November 15, 1738, and he died in Slough, England, on August 25, 1822.
William thereafter found that his health was too delicate to continue with the military, so he left Germany at age nineteen, in 1757, and went to England, where he took up residence.
Herschel concluded from many studies and star counts that the Milky Way System was in the shape of a disk, like a grindstone, and that it had a thickness of about one-sixth of its diameter.

 Herschel, Sir William (1738-1822): World of Earth Science
Herschel's first major discovery occurred in 1781, during his second survey of the sky when he announced the existence of a new planet to be found in the constellation of Taurus.
Herschel's most significant achievements were in the area of sidereal astronomy, to which he contributed the first systematic body of evidence on the order and nature of the stars and the planets.
Herschel devoted most of his attention to examining Saturn and its rings, arguing at one point that the rings were solid, but later conceding that they were in fact composed of floating particles.

Herschel discovered that unfilled telescope apertures can be used to obtain high angular resolution, something which became the essential basis for interferometric imaging in astronomy (in particular Aperture Masking Interferometry and hypertelescopes).
On August 25, 1822, Herschel died at Observatory House, Slough, and is buried at nearby St Laurence's Church, Upton.

Although his name is not attached to a breakthrough discovery resembling that of his father, John Herschel (1792-1871) was regarded by contemporaries as the natural heir to Laplace, no less (incidentally, Laplace was instrumental in confirming mathematically that the 1781 discovery of Herschel senior was indeed a new planet).

William Herschel was born in Hanover, Germany at a time when the city belonged to England under the rule of George II.
Herschel's first telescope, a 6-foot Gregorian reflector, was one of the best of its kind, and he decided that its first application would be to conduct a systematic survey of the stars and planets.
Herschel was fascinated by Saturn's rings, arguing at one point that the rings were solid, but later conceding that they were in fact composed of small, discrete particles.

Sir Frederick William Herschel, FRS KH (15 November 1738-25 August 1822) was a German-born British astronomer and composer who became famous for discovering the planet Uranus.
In particular, he believed every planet was inhabited, even the Sun: he believed that the Sun had a cool, solid surface protected from its hot atmosphere by an opaque layer of cloud, and that a race of beings adapted to their strange environment lived there that had enormous heads.
Herschel, the asteroid 281 Lucretia, and the comet 35P/Herschel-Rigollet are named after his sister Caroline Herschel.

By 1773, Herschel had built a telescope with a focal length of 5.5 ft, and he was now ready to begin observing.
Herschel was searching for double stars with the expectation that a parallactic shift of the brighter component might be detected relative to the fainter and presumably more distant component.

 William Herschel
William Herschel was born in 1738 in Hanover, Germany.
Herschel embraced this idea, which had became known as the “island universe theory” and set out to determine the shape of the Milky Way, by “gauging” the number of stars in a given region.
William had noticed in his survey of the skies that the density of stars varied depending upon what region he was looking at, at the time.

Herschel later quarreled with King George III over the additional funds he demanded for his 40-foot telescope.
Perhaps for this reason, it was only when the King went mad and his son William took over as Regent that Herschel was given the rare distinction of a knighhood, in 1816.
After William's death she prepared a catalog of the star clusters and nebulae that they had observed.
