History of the Department

Paul Poppers, MD Paul J. Poppers, MD, was appointed as the founding Chairman of the Department of Anesthesiology when Stony Brook University Hospital first opened its doors in 1979. Dr. Poppers decided that the department should emphasize all three aspects of an academic department of anesthesiology. Beginning with Maria Lagade, MD, he hired clinical faculty to provide excellent clinical expertise to the operating room. He initiated a Residency Training Program that welcomed its first residents in 1981. Finally, he recruited Roger S. Brett, MD, PhD to develop a basic science and clinical research program.

When the department celebrated its 10th anniversary with a symposium "The Future of Anesthesiology - The Science and the Practice" in 1989, there were 34 clinical faculty members. The training program had grown to 37 Residents. Four basic scientists were performing NIH-supported research in the department's labs. The accomplishments of the department in terms of clinical anesthesia, intensive care, education and basic research had found national recognition for their quality.


In 1990, the department was saddened by the untimely death of our first basic scientist, Dr. Roger S. Brett, due to non-Hodgkin's lymphoma. We dedicated our departmental library to the memory of Dr. Brett.

Dr. Poppers retired in 1999 as Distinguished Professor of Anesthesiology. He passed away in June 2019.


Peter Glass, MB, ChB Peter S. A. Glass, MB, ChB became Chairman of Anesthesiology in the Fall of 1999. Dr. Glass continued the three-fold mission of the department. He anticipated the need for an Ambulatory Surgery Center at the Medical Center and worked quickly to have one opened by 2001. The Center, under the direction of F. Barry Florence, M.B., Ch.B., flourished and annually receives distinctions in patient satisfaction. Dr. Glass recognized the importance of the Anesthesiology Department providing direction for the operating room; Kenneth Rosenfeld, MD, an anesthesiologist, became the Medical Director of the Medical Center's Operating Rooms. Dr. Glass has expanded the department and to include over 75 faculty members including  three Dental Anesthesiologists. The Residency Program grew to a total of 30 trainees in CA1, CA2 and CA3 and another 10 in PGY1. Eight Dental Anesthesia residents joined the training program. Dr. Glass' vision of the educational mission of the department led to a high emphasis on simulation and the teaching of clinical skills. He broadened the research efforts of the department; at his retirement, there were 6 basic scientists and 4 physician scientists.

Dr. Glass retired in July 2013 to start a venture in healthcare in the area of office-based surgery. The annual Academic Research Evening has been named in his honor.
