Andrew P. Weinfeld, past president of the Maryland Society of Internal Medicine, died yesterday of cancer at his residence in Homeland.
Dr. Weinfeld, who was 50, was born in Newark, N.J., and graduated from Rutgers University.
He came to Baltimore in 1962 to attend the Johns Hopkins University School of Medicine School. Following an internship and residency at Johns Hopkins Hospital, he began a fellowship there which was interrupted when he served 2 1/2 years as a major in the U.S. Army in Fairbanks, Alaska.
Dr. Weinfeld later completed his fellowship in nephrology -- the branch of medicine dealing with the kidneys -- at Harvard Medical School. In 1973, he returned to Baltimore and to the private practice of internal medicine, joining the staffs of Johns Hopkins Hospital, Sinai Hospital and Greater Baltimore Medical Center.
