Hamburger, Viktor: Appointment Letters: 1933-69

The papers span in date from 1917 to 2000 and consist of correspondence with colleagues, course lecture notes, lecture and meeting notes, writings, and illustrations (including illustrations for two classics of embryology: the article “A Series of normal stages in the development of the chick embryo” and the book A Manual of Experimental Embryology.) Notable correspondents include Johannes Holtfreter (however, with one exception, the letters in the Holtfreter files are photocopies of the originals), Rita Levi-Montalcini, and Jane Oppenheimer.
