1Author:  Frazer, John Fries, 1812-1872Requires cookie*
 Title:  John Fries Frazer papers, 1834-1871     
 Dates:  1834-1871 
 Abstract:  John Fries Frazer was a prominent Pennsylvania scientist in nineteenth century America, serving as a professor at the University of Pennsylvania and very active in both the Franklin Institute and the APS. This large collection of his correspondence provides a snapshot of the growing scientific community in mid-nineteenth century America. Frazer's correspondence involves a wide range of topics: science and scientific institutions (shipbuilding, mechanical engineering, geology, geography, astronomy, chemistry, among others), although there are fragments of personal correspondence. His range of correspondents is as diverse as the topics, but there is a notably large collection of letters from scientific heavyweights Titian Ramsey Peale, Louis Aggasiz, Joseph Henry, and Alexander Dallas Bache.

 Title:  Robert M. (Robert Maskell) Patterson papers, 1775-1853     
 Dates:  1775-1853 
 Abstract:  The Robert Patterson Collection contains a range of documents that touch on many different topics, although most have to do with science and engineering. The earliest documents relate to the Leiper Canal, including Rittenhouse's appraisal of it, and official documents relating to its creation. The largest portion of the documents is scientific correspondence to Robert Patterson, a member of the American Philosophical Society. Much of this correspondence is done under the cover of official APS business. Of particular note are a series of letters relating to nautical calculations that include complex equations used to determine longitude and latitude for nautical almanacs. There are also various lecture notes on natural philosophy, death, mathematics, engineering, and other subjects.
