Roth and Diana Roth Lazar; grandchildren, Laura Lazar, Michael August Young, Jennifer Lazar, Joseph Roth and Franklin Roth After graduating in 1951 from the University of Illinois with a PhD in Geology, Dr. Roth worked at the National Bureau of Standards (later known as National Institute of Standards and Technology) from 1951-1991 as a Supervisory Research Chemist in the Microstructure Section, Mineral Products Division and then as Chief of the Solid State Chemistry Section, Ceramics/Inorganic Materials Division. From 1991 until his death, he served as Scientist Emeritus, NIST Ceramics Division as well as a consultant to the Structure Determination Methods Group, American Ceramic Society. He served as a senior editor for numerous volumes of Phase Diagrams for Ceramists and Phase Equilibria Diagrams which both serve as a resource for industry in the design and processing of technological ceramics. His publications include over 200 technical papers in the fields of x-ray crystallography, crystal chemistry, and phase equilibria of ceramic materials. Some of the materials he helped develop have been utilized for: Increasing the fidelity of phonograph needles used in record players; Improving sonar during the Korean War; Fuel rods of modern nuclear reactors; Containment of nuclear waste; The solid-state electronic chip; Cubic zirconium often found in jewelry; Fire retardant ceramic tiles used to surround the Space Shuttle; Counterfeit proof ink used in new American Currency Member of Mineralogical Society of America (fellow); American Ceramic Society (lifetime member) ; The Geological Society of America (fellow); American Crystallographic Association, Washington Academy of Sciences (fellow); Mineral Society of Great Britain and Ireland His Awards include: Spriggs Phase Equilibria Award, Lifetime achievement in the field of experimental ceramic phase equilibria, American Ceramic Society, 2003; Wilhelm R. Buessem Award , Pennsylvania State University, 2001; John Jeppson Award, American Ceramic Society, 1995; Sosman Award, American Ceramic Society, 1991; Gold Medal, U.S. Department of Commerce, 1986; NBS Special Service Award, Meritorious Publication, 1963; and the Silver Medal, U.S. Department of Commerce, 1962 Patents include: US-4,606,906 Aug 19, 1986; "Process of Synthesizing Mixed BaO-TiO2 Based Powders for Ceramic Applications" and US-2,849,404 Aug 26, 1958; "Morphotropic Piezoelectric Ceramics"
