John Bevis
John Bevis (November 10th 1695 - November 6th 1771) is a Médecin and British Astronome amateur . He is known amongst other things to have discovered the Nébuleuse of the Crab. He was born in Old Sarum, in the county of Wiltshire.
In 1731, Bevis is the first to observe the Nébuleuse Crab, 27 years before Charles Messier it redécouvre independently in 1758. Work and the catalog of Messier gaining in popularity with the passing of years, Bevis takes note of the catalog of diffuse objects of Messier and informs it by letter, dated June 10th 1771, which it itself had already observed indicated nebula M1 by Messier, this last adding thereafter a note in the later editions of the catalog to recognize the paternity of discovered in Bevis.
John Bevis is also the first and until now the only observer to be had provides a detailed report/ratio of an extremely rare astronomical phenomenon: the Screening of a planet of the Solar system by another, in fact the screening of Mercury by Venus on May 28th 1737.
In 1738, Bevis is made build a astronomical Observatoire private with Stoke Newington, in the Middlesex, from which it carries out the observations intended for the preparation of its own celestial atlas: Uranographia Britannica , completed in 1750. Unfortunately, the editor of Bevis, which financed the work, made bankruptcy right before the impression of the atlas, and engravings were put under seal. Only some specimens of the work were finally printed in 1786, well after the death of Bevis, under the celestial title Atlas , and without the name of John Bevis not being mentioned.
Bevis is one of the two only British (with Nicholas Munckley, him also doctor) having in an unquestionable way observed the first return of the Halley's Comet to be envisaged by calculation. It personally observed it May 1st, th and 2nd 1759. Bevis becomes member of the Royal Society the November 21st 1765.
It also observed the Transit of Venus in front of the Sun in 1769. It is on this occasion the first to be described and make a precise drawing of the “Phénomène of the black drop”, during which the apparent Venus shape appears slightly deformed just at the times when this one is in contact with the edge of the solar disk.
John Bevis dies in 1771, at the 76 years age, apparently of the continuations of wounds caused by a fall of his telescope.
