Named in honor of Paul Joseph Steinhardt (25 December 1952, Washington, D.C., USA), Professor at the Department of Physics of Princeton University for his extraordinary and enthusiastic dedication to the study of the mineralogy of the Khatyrka meteorite. His work has covered a vast range of problems in particle physics, astrophysics, cosmology, and condensed matter physics. He coauthored the description of the first natural quasicrystal, icosahedrite from the Khatyrkite meteorite.
