EDWARD L. FIREMAN 148, a physicist at the Smithsonian Astrophysical Observatory (Cambridge, Mass.) and a recognized authority on analysis and dating of extraterrestrial materials, died of a heart attack Mar. 29, 1990. He was 68 years old. Born in Pittsburgh, Penn., he graduated with a bachelor's degree from Carnegie Inst. of Technology in 1943 and was awarded his Ph.D. in physics at Princeton. Graduate work and early employment at Brookhaven Natl. Laboratory in nuclear physics provided him special expertise. He developed techniques for analysis of radioactive isotopes in meteorites to determine time of exposure to cosmic rays traveling through space. His procedures were also applied to lunar specimens returned to earth by the Apollo astronauts. Most recently his research involved the pursuit of solar neutrinos, placing detectors 800 feet deep in the Homestake Gold Mine (South Dakota), using the overlying soil and rock as a filter to remove extraneous radiation.
Sincere condolences are proffered to his widow, Rita, three children, four grandchildren, and three siblings.
