In Memoriam: Paul Numerof, PhD, and Arthur Weiss, BS, JD, PhD

This January, the field of nuclear medicine and molecular imaging lost two men who made a significant impact on the specialty.

Paul Numerof, PhD, passed away on January 12, 2013. He began his career in the sciences working on the Manhattan Project, where he led a team in developing a process to purify uranium that had been used in experiments. After receiving his doctorate, Numerof was led to the medical sciences where he played a role in the development of medical isotopes for use in oncology and pulmonology. He also developed small nuclear isotope generators to make body scanning agents in hospitals. He had an international reputation, lecturing worldwide and publishing many scientific articles.

Contributions in his honor may be made to the Dr. Paul Numerof Memorial Fund at the Los Alamos Historical Society, P.O. Box 43, Los Alamos, NM 87544 or to the Dr. Paul Numerof Memorial Education Fund at B'nai Vail, PO Box 6068, Vail, CO 81658.

Arthur Weis, BS, JD, PhD, who passed away on January 20, 2013, was a pioneer in the development of nuclear medicine and founder and chair of the board of Capintec, Inc., which manufactures radiation dose calibrators and other nuclear medicine instruments. He previously served as president and director of Brevatome USA, Inc., and was a consultant to the French Atomic Energy Commission, the Italian Atomic Energy Commission, and numerous Japanese companies in nuclear power and nuclear medicine. He held a number of U.S. patents for isotope devices.                                                                                      

In 2008, Weis received the SNMMI Presidential Distinguished Service award in recognition of continual dedication to the society.He was a member of the Greater New York Chapter of SNMMI and served on the isotope availability and audit committees.
