David Edward Pritchard (born October 15, 1941 in New York City) is physics professor at the Massachusetts Institute of Technology (MIT). Professor Pritchard carried out pioneering experiments on the interaction of atoms with light that led to the creation of the field of atom optics. His demonstration of the diffraction of a beam of atoms by a grating made of light waves opened the way to studies of the diffraction, reflection, and focusing of matter waves, similar to those with light waves. He has applied atom optics to basic studies of quantum theory, to new methods for studying the properties of atoms, and to the creation of devices such as the atom interferometer and atom wave gyroscope.
