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.
Is drawing up a new actinometer and comments on JF's ideas about it. Encloses a letter to JF's brother.
Gives JF permission to use JH's letter to JF's brother in any way JF sees fit to obtain the Chair of Natural Philosophy (at Edinburgh), but still does not wish directly to promote JF's selection. Briefly discusses results of JF's experiments with the actinometer.
Returned suddenly from the continent and found JH's letter to his brother awaiting him. Outlines his reason for applying for the vacant post at the University and would welcome a testimonial from JH. Brewster is his chief rival. Gives a few observations on his recent trip to the continent.
Is sorry to trouble him again but would like a letter from JH that he can print with his testimonials, as David Brewster has now printed JH's letter, also [William?] Ritchie. Awaits the results before setting out for Europe.
