Editing Bernard Lyot (section)

==Biography==
An avid reader of the works of [[Camille Flammarion]], he became a member of the [[Société Astronomique de France]]  in 1915 and made his first observations using the society's telescope on rue Serpente in Paris.<ref>[http://adsabs.harvard.edu/full/1952LAstr..66..265D D'Azambuja, L. "L'œuvre de BERNARD LYOT,"] [[L'Astronomie (magazine)|L'Astronomie]], Vol. 66, p.266.</ref> He soon acquired a {{convert|4|in|mm|adj=on}} telescope and soon upgraded to a {{convert|6|in|mm|adj=on}}. From graduation in 1918 until 1929, he worked as a demonstrator at the [[École Polytechnique]] and studied [[engineering]], [[physics]], and [[chemistry]] at the [[University of Paris]].

From 1920 until his death he worked for the [[Meudon Observatory]], where in 1930 he earned the title of ''Joint Astronomer of the Observatory''. After gaining the title, he earned a reputation of being an expert of polarized and monochromatic light. Throughout the 1930s, he labored to perfect the [[coronagraph]], which he invented to observe the [[solar corona|corona]] without having to wait for a solar eclipse. Most of this work implied painstaking long observations at the [[Pic du Midi de Bigorre|Pic du Midi]] Observatory. It was an exceptionally good site, free of both air pollution and [[light pollution]] but it came with a disadvantage: In the interwar period access to the peak implied mountaineering skills and physical fitness, especially in winter when access was only gained with a long and tiresome [[ski touring]] trek on sealskin-fitted skis, a technique mastered by Lyot, a keen sportsman and mountaineer.<ref>{{Cite web |title=Comprendre - Histoire de l'observatoire du Pic du Midi |url=https://promenade.imcce.fr/fr/pages5/545.html#th5 |access-date=2023-09-05 |website=promenade.imcce.fr|lang=fr}}</ref> Accommodation on site can only be described as spartan, before a powerline, a bigger refuge and a cablecar were built in the early 1950s. In 1938, he showed a movie <ref>{{Cite web |title=Flammes du soleil |publisher= CNRS Images |url=https://images.cnrs.fr/video/1348 |access-date=2023-09-05 |website=images.cnrs.fr |language=fr}}</ref> of the corona in action to the [[International Astronomical Union]]. In 1939, he was elected to the [[French Academy of Sciences]]. He became Chief Astronomer at the Meudon Observatory in 1943 and received the [[Bruce Medal]] in 1947.

Lyot was the President of the [[Société astronomique de France]], the French astronomical society, from 1945-1947.<ref>[[Société astronomique de France|List of presidents of the Société astronomique de France]]</ref>

He suffered a heart attack while returning from an eclipse expedition in Sudan and died on 2 April 1952, at the age of 55.<ref>{{cite journal |title=Bernard Lyot |url=https://physicstoday.scitation.org/do/10.1063/PT.5.031424/full/ |journal=Physics Today |date=2017 |issue=2 |page=9320 |doi=10.1063/PT.5.031424 |bibcode=2017PhT..2017b9320. |access-date=8 February 2021|url-access=subscription }}</ref>
