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.
Observations on [double] stars. Congratulations [on birth of Isabella Herschel].
Received JH's 'Fourth Series of Observations...' [1831] on double stars. Donated it to College library.
JW's observations of Jupiter on 15 Apr. 1826, with all satellites hidden. This confirms similar observation by [Samuel] Molyneux quoted in JH's [Treatise Astr.]. Has JH's letter of 29 Aug. 1819 relating to spots on Jupiter's disc. [JH annotation: 'To be added to my Astronomy.']
Pleased by account of JH's wife and new baby [Isabella]. Copies passage and diagram from letter of Welsh clergyman trying to construct sound amplifier for pulpit. Asks JH to offer solutions. Husband L. P. Wilson sends regards. Forwarded JH's letters to FW's sister [Maria Edgeworth] in Ireland.
Comments on efforts toward getting a royal charter for the Astronomical Society, a paper by Peter Barlow, and activities of the R.S.L. Correspondence with Wilhelm Struve. Difficulties in getting his new telescope constructed.
Has received JH's communication. Asks that JH not write JS unless he can write in a 'different manner.'
Regrets the tensions that arose between JH and JS. Congratulates JH on his knighthood. Laments the costs and difficulties involved in the construction of JS's new observatory.
Sends JH a copy of Richard Jones's new book [Essay on the Distribution of Wealth]. Congratulates JH on the publication of his new book [Prelim. Discourse].
Returns the collection of optical writings that JH had sent. Comments on the controversy over the nature of light. Criticizes paper by Richard Potter attacking JH and other wave theorists of light.
Comments negatively on whether photonomy is a proper name for the study of light. Has suggested that the B.A.A.S. invite eminent scientists to survey their specialties. Discusses whether B.A.A.S. should meet at Cambridge. Has published his review of JH's Prelim. Discourse.
Is grateful for the copies of his notes on his observations. Has compared them with his own and found them remarkably similar. JH should see Mr. Hildyard of Eton if he wishes to compare notes on their expeditions. Regarding JH's measurement of Etna.
Just before the death of her husband he received a letter announcing JH's intention of visiting the Cape. Would be pleased to provide him with any information if he desires it.
Grateful for JH's kind letter, but will be unable to visit him as her time is taken up visiting relations. Will send some Cape bulbs if Lady Herschel would like them.
Comments on some of JH's geological papers. Has received a paper on Yorkshire geology from R. I. Murchison.
When they last met, JH had promised to show him some of the wonders of his 20-ft. reflector. Is in town for a few days and would welcome the chance of visiting him.
