About this book

The large telescope at Meudon has become legendary. When it was conceived, after 1870, astronomy as a whole was limited to visual observation. Knowledge of the sky was limited to what one could see, assisted only by optical means. The large telescopes produced at this time produced larger images, permitting close-up views: the Meudon telescope was able to accomplish this perfectly.
 
At Meudon, which became the Mecca of visual observation, the major planets were examined in a way that no other telescope had previously been able to. The telescope monitored the state of their atmospheres and mapped the appearance of their surfaces.  Through the telescope, one could obtain photographs showing the nuclei of comets, revealing their very small size, and by using an eyepiece one could measure the separation of double stars.  With a marvellous little instrument, the polarimeter, the nature of clouds in planetary atmospheres has been determined, and the type of surface material identified. Many more results were obtained, while photography, universally adopted, revolutionized other knowledge about the world.  The sensitive emulsion, combined with large aperture reflecting telescopes, revealed the deepness and richness of the cosmos.  The vast telescope of Meudon, which was the largest refracting telescope in Europe, became a legendary instrument and was symbolic of a new way to practice astronomy.
 
Audouin Dollfus, a renowned astronomer, describes the great years of the Meudon telescope.  He gives us the entire story of this instrument, from the birth of the concept that drove Jules Janssen at the end of the nineteenth century, to the idea that French astronomy could provide an outstanding telescope which would approach the limits of technical and industrial resources.  The telescope remained unchanged until 2006, when the first steps toward restoration and public reopening were taken.

About the author

Audouin Dollfus had developed research in astronomy at the Meudon Observatory from 1945 on. He was an honorary astronomer of the Paris Observatory, and his work on the planets, the solar corona, astronomical instrumentation, and the observer telescopic ball earned him the Grand Prix of the Academy of Science and the Jules Janssen Gold Medal of the Astronomical Society of France. He also established three world records in ballooning, including the first manned(!)stratospheric flight in France. He died in 2010 at the age of 85.
