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.
Recovering from a prolonged illness. Discusses parallax. JH reports that he now is very skilled at sweeping with the 20-ft reflecting telescope.
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.
Studied 659 double stars; JH is confident that his work proves his father's conclusions. Now plans to study nebulae.
