Hans Christian Adamson

Name:Hans Christian Adamson

Birth: 20 Jul 1890

Place: Varde, Denmark

 

 Today is the anniversary of the birth of the Danish-born American writer Hans Christian Adamson. He is probably best remembered by astronomers as editor of ‘The Hayden Planetarium Bulletin’ and ‘The Sky’ (two of the ancestors of Sky & Telescope). 


The Hayden Planetarium Bulletin was issued as a monthly publication by the American Museum of Natural History from November 1935 to October 1936, following the opening of the Hayden Planetarium. Within twelve months the bulletin had become a full-size magazine and was renamed ‘The Sky’, featuring well-illustrated articles written by astronomers from across the world. 


Hans Christian Adamson edited The Sky from October 1937 to February 1938, at which point George Clyde Fisher, head of the Hayden Planetarium, took over the role.

 Name: Albert Francis Arthur Lofley Jones Birthdate: 9 Aug 1920 Birthplace: Christchurch, New Zealand   Today is the anniversary of the birth of amateur astronomer Albert Francis Arthur Lofley Jones. His achievements include the discovery (on 6 Aug 1946 while observing the variable star U Puppis) of comet C/1946 P1 (Jones) and the co-discovery on 18 Nov 2000 (with astronomer Syogo Utsunomiya of Kumamoto, Japan) of the long-period comet C/2000 W1 (Utsunomiya-Jones) (pictured here on 18 Jan 2001).  He was also the co-discoverer of supernova SN 1987A (seen here as the bright star to right of centre of image) in the Large Magellanic Cloud. However, Albert Francis Arthur Lofley Jones is perhaps best remembered for his remarkable skills as a variable star observer.  He was also the co-discoverer of supernova SN 1987A (seen here as the bright star to right of centre of image) in the Large Magellanic Cloud.

Name: Laurent Cassegrain Birth: around 1629 Birthplace: Chartres,France     Today is the anniversary of the Birth of the French Catholic priest and instrument maker Laurent Cassegrain. Although this image may be a likeness of Laurent Cassegrain, no verifiable portrait of him is known to exist. he is best known to astronomers as being the probable inventor of a type of reflecting telescope which uses a combination of a primary concave mirror and a secondary convex mirror .  Now known as the Cassegrain reflector, Cassegrain’s design first appeared in the 25 Apr 1672 issue (pictured) of Le Journal des Sçavans (established by French writer Denis de Sallo in 1665 and the earliest academic journal published in Europe).  The 55 km diameter lunar crater Cassegrain, located to the south east of the larger crater Lebedev on the far side of the Moon and seen here immediately to the lower right of image centre, is named in his honour.

  Today is the anniversary of the birth, at Woolsthorpe, near Grantham, Lincolnshire on 25 Dec 1642, of the English physicist, mathematician and astronomer Sir Isaac Newton .     Although his achievements were many, he is probably best remembered for his ‘Philosophiæ Naturalis Principia Mathematica’ (Mathematical Principles of Natural Philosophy). Often referred to as ‘The Principia’ and widely considered as being one of the most important works in the history of science, its contents i ncluded details of Newton's laws of motion (which went on to form the basis of classical mechanics) together with his famous law of universal gravitation. The 79 km diameter lunar crater Newton, located in the south polar region close to the southern limb of the Moon, and seen here with the satellite crater Newton D overlying its north-northeastern rim, is named in his honour.  Credit: societyforthehistoryofastronomy.com
