In Memory of Dr. Sidney Udenfriend

I was deeply shocked and extremely saddened, when I received the news that Dr. Sidney Udenfriend had passed away on December 29, 1999, after his cardiac surgery. I had had a long talk by telephone with Dr. Sidney Udenfriend at his home in New Jersey on August 6, 1999, when I was at the NIH as a Fogarty Scholar. I wanted to see him, but his health condition did not permit my visit. When I talked with Dr. Udenfriend, he was very kind and encouraged me to continue my research, as he always did whenever I talked with him.
