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.
Sends letter from 'chronometer expedition' in Baltic Sea under the leadership of [T. F.] Schubert and supported by the Prussian, Danish, and Swedish governments. Mentions talk written for a larger audience in French publication. Envies JH's opportunity to observe the southern hemisphere.
Promises to write JH more often at the Cape. Is waiting for JH's work on nebulae. Promises to send his work on 3000 double stars. Plans to begin work on parallax of fixed stars.
Reports the death of family members. Reveals news of new Pulkowa observatory. Has completed his work on micrometer measurements, resulting in 10,500 observations. Includes lists of aspects of his works.
Has spent much time in Petersburg dealing with Pulkowa affairs. Mentions his works that he has recently sent to JH. Thanks for comments on his 'Mensurae Micrometricae.' Looks forward to publication of JH's work at the Cape. Discusses suitability of the Russian winter for astronomical work. Requests JH's opinion of the instruments made by [J. G.?] Repsold and designated for Pulkowa. Comments on the heliometer. Invites JH to opening of Pulkowa Observatory.
Rejoices at welcome JH received on returning to England from the Cape. Excellent resources at his disposal at Pulkowa. Mentions coin, commemorating opening of the observatory, sent to JH by means of [H. C.] Schumacher. Refers to [Otto] Struve's work on double stars. Lauds capacity of large refractor at Pulkowa Observatory.
Regrets that his work at Pulkowa eliminates the possibility of being absent for longer periods of time and hopes to see JH in Russia. Mentions his and his son Otto Struve's most recent work. Wishes JH well in his new home at Collingwood.
Thanks JH for his letter [1841-10-10]. Discusses difficulty of measuring distance between a star of primary largeness and a small telescopic neighbor star. Rejects theory that temperature influences observation results. Appreciates JH assessment of the correspondence between WS's work and that of [F. W.] Bessel. Complains confidentially that Bessel neglects to acknowledge WS's work on parallax, begun a year before Bessel's own. Assures JH of WS's continual efforts in observing new phenomena. Comments on JH's 'On the Revision and Rearrangement of the Constellations.'
Sends this letter through his son Otto Struve. Informs JH of his upcoming visit to England and desires to renew the acquaintance at Collingwood.
Notifies JH of his and [P. A. ] Hansen's arrival in Greenwich from Gotha. Plans on visiting JH the following day via Staplehurst.
Mortified at Punch cartoon libeling WS's sovereign. Enjoyed WS's visit and invites Otto Struve again. Request WS to give [G. B.] Airy his 'full impressions' of Munich glass as opposed to British glass. Supports British glass for Cape's colonial instruments.
Introduces [Wilhelm] Döllen, who wishes to meet JH. WS recommends Munich glass for the Cape telescope.
Description of Pulkowa observatory sent fourteen days before. Included a listing of the library. Otto Struve works on micrometer measurements of double stars. Complains about [J. H. von] Mädler's unprofessional attitude at Dorpat. Announces 'Neptune' as new planet's name.
Sends paper on naming of Neptune. Denounces elimination of [J. C. ] Adams's part versus U. J. J. Le Verrier's role regarding Neptune. Will forward Otto Struve's paper on the expedition between Altona and Greenwich and his own Positiones mediae stellarum fixarum.
Has arrived from Paris and will continue to Hamburg. Regrets not being able to revisit Collingwood. Requests JH's work concerning the southern skies.
Acknowledges receipt of JH's Cape Results.
Thanks for dedication of WS's publication on double stars to JH's father and to F. W. Bessel. JH's 'present position' cuts JH off from active pursuit of scientific research. Compliments WS's accomplishments and those of WS's son, whom JH expects in England come summer.
WS was elected associate of Astronomical Society. Distributed books as WS directed. Will send JH's and James South's observations of double stars when printed. Neither Thomas Young nor William Herschel received WS's Dorpat observations.
