This collection consists primarily of W. W. Hansen's correspondence with professional colleagues (1934-1949, Boxes 1-3), although
some letters of a more personal nature are also included. These letters were in no particular order when acquired by the Archives.
They have been arranged chronologically, incoming and outgoing correspondence interfiled, and a name index to major correspondents
has been compiled. This index also covers a group of letters and memoranda dealing with the formation of the Stanford Microwave
Laboratory, later re-named the Hansen Laboratory of Physics. This latter group of correspondence (Box 4, folders 40 thru 42)
had been separated from Hansen's other files by his executor, D.L. Webster, who "bound" these letters together in a notebook.
Major correspondents in the W.W. Hansen Papers include: Felix Bloch, Edward Bowles, Ed Condon, E.S. Erwin, Paul Kirkpatrick,
Philip M. Morse, Sperry Gyroscope Co., David L. Webster, Ray Lyman Wilbur, and John R. Woodyard. Although this collection
includes several letters from Hansen to the Varian brothers, there are almost none from the Varians to Hansen.
