FIRST PRINTINGS. 16 offprints. We are pleased to offer a collection of 16 offprints by Gerhard Fankhauser. Fankhauser (1901-1981) was a professor of biology at Princeton University and an expert on embryology and cell biology. Born in Switzerland, he received his Ph.D. at the University of Berne and came to America in 1929 as a Rockefeller research fellow, joining the Princeton faculty two years later. He was internationally known for his research on the development of amphibia. In experiments using hormone manipulation and cross-breeding techniques, he studied the control of chromosomes on the amphibian life cycle. His research showed that the size of a cell is directly related to the number of chromosomes it contains. Quite popular at Princeton, he was the author of well over one hundred papers and reviews. 1. "Cytological studies on egg fragments of the salamander triton. II. The history of the supernumerary sperm nuclei in normal fertilization and cleavage of fragments containint the egg nucleus." Offprint from the Journal of Experimental Zoology, Vol. 62, No. 1, May, 1932. Pp. 185-235. Original printed wrappers. With 4 full-page plates containing 47 illustrations and accompanying explanations and additional text illustrations. Presentation signature from the author on the top of the front wrapper. 2.
