John D. Baldeschwieler is an American chemist who has made significant contributions in Molecular Structure and Spectroscopy. He was born on November 14, 1933 in Elizabeth, New Jersey, United States. Prof. Baldeschwieler received his undergraduate degree in Chemical Engineering from Cornell University in 1956 and his Ph.D. in 1959 in Physical Chemistry from the University of California, Berkeley. Baldeschwieler pioneered the utilization of nuclear magnetic resonance and double resonance spectroscopy, nuclear Overhauser effects, ion cyclotron resonance and perturbed angular correlation spectroscopy in chemical problems.  The research of Prof. Baldeschwieler concentrated on the use of phospholipid vesicles in cancer diagnosis and therapy, on the development of scanning tunneling and atomic force microscopy for the study of molecules on surfaces, and on novel techniques for producing combinatorial arrays of oligonucleotides.  Prof. Baldeschwieler received the National Medal of Science in 2000 for his contributions to science and public service and has also received the American Chemical Society 2001 Award for Creative Invention and the 2003 Othmer Gold Medal of the Chemical Heritage Foundation.
