A native of Wilmington, Del., Nathans shared the 1978 Nobel Prize in Medicine for his work using restriction enzymes, laying the groundwork for the present worldwide effort to map the human genome. After graduating from the University summa cum laude, with distinction in chemistry, Nathans went on to receive a medical degree from Washington University in St. Louis in 1954. A member of the Hopkins faculty since 1962, he will lead the university during its search for a new president and an ongoing $900 million fundraising initiative. Nathans said he would not be a candidate for the permanent post. In 1993, he received the nation's highest award in science-the National Medal of Science.
