Biography
Paul was born in 1908 to a prominent German family in Rochester. BS in Chemical Engineering from Massachusetts Institute of Technology in 1930.  University of Rochester: Fellow in Chemistry and Experimental Pathology (1932-36), Assistant in Pathology (1936-37).  PhD in Biochemistry in 1936 . Instructor in Chemistry and Experimental Pathology in 1937, Associate in Chemistry and Experimental Pathology from 1940-1943 at Rochester. He worked with George Whipple  (Noble prize 1934). Paul was the first to use Fe-59 to study iron requirements in anemic dogs, and in human pregnancy.

Paul came to Vanderbilt in 1943, where he extended his Fe-59 investigations of nutritional requirements of pregnant women. Hahn worked in Biochemistry at Vanderbilt through 1947 with support from the Nutrition Program (with Bill Darby,  Chair of Biochemistry).  Hahn mentored Meneely at University of Rochester, and at Vanderbilt, they collaborated on many projects  during the years 20 years they worked in Nashville.  Paul moved his primary affiliation to Meharry Medical College about the time Meneely moved the Vanderbilt radioisotope program to the Nashville VA.   Paul continued as a Consultant to the Vanderbilt program at the VA.  One project involved  the development, testing, and imaging of radioactive colloids in cancer therapy. Bill Meacham, Chair of Neurosurgery at Vanderbilt, worked with Hahn and Heyssel in the late 50s and early 60s in an attempt to treat hydrocephalus in children by injecting colloidal Au-198 into the lateral ventricles to decrease the secretion of cerebrospinal fluid (CSF) from the choroid plexus.

In 1960, Paul moved to Bethesda, MD where he joined the National Institutes of Health as the Head of the Division of Radiological Health,  Radiation Effects Study Section.  It is likely that he died there around 1967, but his obituary has not been found.
