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.
Packing up the 7-ft. and 10-ft. reflecting telescopes for their trip to Collingwood in Hawkhurst in Kent, JH's new home.
Gives reasons why CH rejoiced at news of Mrs. Papendick's death, and grieves that two daughters of Papendick are gaining influence at Court.
Hopes to introduce to Margaret Herschel some of her acquaintances, including the family of General Baron Hugh Halkett.
Reports that there is no bust of William Herschel at the R.S.L., as JH once believed.
JH has given away his sweeping telescope to [Johann] Hausmann and the 5-ft. Newtonian reflector to the R.A.S. to be preserved 'long after I and all the little ones are dead and gone.' The skies have been excellent for JH to observe variable stars and to connect the northern with the southern magnitudes. Proved that Alpha Orionis is both a variable star and a periodical star.
Asserting that her memory remains sharp, CH promises that she will periodically describe 'what passed in old times.'
JH and family are beginning to feel at home at Collingwood.
