Robert M. Silverstein, PhD was as born in Baltimore, MD, and moved to Staten Island at a young age. He received his bachelor's degree from the University of Pennsylvania in 1937 and his masters' degree from New York University in 1941. He served with the U.S. Army during World War II. He then earned his doctorate from New York University.Francis X. Webster is the author of Spectrometric Identification of Organic Compounds, 8th Edition, published by Wiley.David J.
