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.
Asking for a photograph of himself [see JH's 1853-11-[10]]; complains about the binders putting too much material in one book; talks about daughter Caroline spending much time at Windsor.
Willingly gives JH permission to engrave a portrait photograph taken with WT's process. WT asks JH if he would be willing to testify on WT's behalf if necessary, relating to infringement of patent rights. WT announces that John Hind has discovered another asteroid [Euterpe].
