The Sir John Herschel Collection
The preparation of the print Calendar of the Correspondence of Sir John Herschel (Michael J. Crowe ed., David R. Dyck and James J. Kevin assoc. eds, Cambridge, England: Cambridge Univ. Press, 1998, viii + 828 pp) which was funded by the National Science Foundation, took ten years. It was accomplished by a team of seventeen professors, visiting scholars, graduate students, advanced undergraduates, and staff working at the University of Notre Dame.
The first online version of Calendar was created in 2009 by Dr Marvin Bolt and Steven Lucy, working at the Webster Institute of the Adler Planetarium, and it is that data that has now been reformatted for incorporation into Ɛpsilon.
Further information about Herschel, his correspondence, and the editorial method is available online here: http://historydb.adlerplanetarium.org/herschel/?p=intro
No texts of Herschel’s letters are currently available through Ɛpsilon.
Informs CH of his gold medal from the French Academy of Sciences for JH's and James South's paper on double stars. Finds CH's catalogue of nebulae in zones very useful. Heard about Johann Pfaff's death. James Grahame may be moving to Göttingen.
Her social life is rather boring at the moment because CH is busy caring for her sick brother Dietrich.
Recovering from a prolonged illness. Discusses parallax. JH reports that he now is very skilled at sweeping with the 20-ft reflecting telescope.
Discusses nebulae. Begs JH not to overwork himself. Hopes to live long enough to see JH marry; advises JH that if he can marry a 'good-natured, handsome, and sensible young lady, pray think of it, and do not wait till you are old and cross.'
Sent to CH a copy of James South's second paper on double stars and a synoptic catalog of them. Calls CH one of the first discoverers of the 'comet of 1795.' Sent to Astronomical Society a report on 300 new double stars.
Discusses her will.
Studying the volcanoes of Auvergne; hopes to use his newly-created actinometer at the Puy de Dôme.
Pleased that JH supports CH's plans for her will. Worries about JH's safety at Puy de Dôme.
The first volume of Johann Pfaff's German translation of William Herschel's papers has been published; asks JH to inform her whether he wants a copy. Commenting on her boredom, CH laments that her 'sole employment consists in keeping myself in good humor and not be disagreeable to others.'
[Addition to Mary Baldwin's letter.] Health of JH's uncle. Travels through volcanic country of Vivarais. Asks CH to purchase for JH 10 copies of the first volume of William Herschel's works, recently translated into German. Sent to CH six copies of JH's 'Account of a Series of Observations Made with a 20-feet Reflecting Telescope' (1826) via Mr. Golterman, and six copies of JH's 'On the Parallax of the Fixed Stars' (1826) via Capt. Müller. James South received Copley Medal this year. Asks about comet near sun on 18 Nov.
Describes her role in William Herschel's work as 'a mere tool which he had the trouble of sharpening and to adapt for the purpose he wanted it.' Sending to JH the first volume of Johann Pfaff's translation of William Herschel's papers in three weeks; believes that JH will be unhappy with it.
Sending a copy of Johann Pfaff's German translation of William Herschel's papers.
Discussing William Herschel's financial difficulties, CH confides that 'she never felt satisfied with the support your father received toward his undertakings, and far less with the ungracious manner in which it was granted.' Regrets WH was not able to do more work with the 40-ft. reflecting telescope.
Received the first volume of Johann Pfaff's German translation of William Herschel's papers. Just completed a second catalog of double stars; review of nebulae going slowly. JH comments on his precise sweeps.
She 'can only think of what is past, and is for ever forgetting the present.'
Feels distant from her family in England. Notes that the French occupation has changed Hanover from what it was when CH left in 1772.
Thanks JH for sending his second catalog of double stars; remarks that 'by the manner in which you gentlemen now attack the starry heavens, it seems that there will soon remain nothing to be discovered.'
Writing her memoirs, CH sends for JH's perusal an account of her youth.
Discusses the poor health of Heinrich Olbers, and Johann Encke's inability to acquire the necessary instruments. Wants JH to send to CH a few of her 'Indexes.'
Hopes to send to CH a catalog of new double stars soon. JH is very disappointed with Johann Pfaff's German translation of William Herschel's papers.
