4 pages (five with overwriting on page 3). Edward Pickering had just graduate from Harvard and became a Professor at the Massachusetts Institute of Technology. He later made the Harvard College Observatory known and became a leading writer on astronomy and after questioning Niels Bohr on atomic structure, he became convinced of Bohr's theories. He is writing to his friend Conwell who was classmate from the Lawrence Scientific School. He writes of his collection of photographs of bridges, he notes he has over 100 stereoscopic views from Europe (courtesy of Anthon in New York), He notes a Professor E. is interested in the project. He inquires about the bridge at St. Paul over the Mississippi as well as the Railroad Bridge, notes the one destroyed by weather, notes the Bangor Bridge in Maine with nice description, says class he is teaching has twenty promising young men, a very nice letter. Later this fascination with photography led to his method to photograph the spectra of multiple stars by putting a large prism in front of the photographic plate. A bit of staining to last letter.

The six page letter from Edward Charles Pickering who was soon to be appointed Professor of Physics at MIT, to his friend and classmate at the Lawrence Scientific School. Much of this letter is technical with exact formulas which require a serious background in advanced mathematics. He notes Rankin's formula in detail and notes the integration of 689 which he thinks is lacking the minus sign. Notes on issues of hydraulics, that while he knows little about back water, he should use the formula of D'Aubuisson de Voisins, Jean-Francois, (1769-1941) and many other details. He goes on to note that Wisbach deals with this and the works on river improvements by W.A. Brooks, E.H. Color and J. White are helpful as well as the common works on hydraulics which can be obtained from the Astor Library. He sends some work for the photographs his friends had sent but would like images of the Minneapolis Bridge for Prof. Eustis [Henry Lawrence, 1819-1885] whether or not stereoscopic. He made his first appearance in public giving an account of the Washington Aqueduct at the Institute of Technology [the future MIT where he would in a few months be appointed as Professor Physics there]. We have transcribed part of the letter in more detail though not as complete as the images on our website.
