2018: Prof. Samuel A. Werner

For his seminal contributions to the observation of the fundamental quantum- mechanical nature of spins through the effects of rotation and the gravitational field, using neutron interferometry, including the observation of the Aharonov- Casher effect, for his extensive work with neutron scattering on the magnetic properties of transition metals and their alloys, for his critical role in the NSSA, particularly as its Founding President, and for his wide and lasting influence on the neutron community, including nurturing of many neutron scientists.
