Nacogdoches in Nacogdoches County, Texas — The American South (West South Central)
Dr. Joseph William Kennedy, Jr
While at U.C. Berkeley, Kennedy and colleagues Arthur Wahl, Glenn Seaborg and Edwin McMillan discovered the element plutonium and developed a method of separating it from other fuel material in a nuclear reactor. Kennedy also designed and built detection instruments, Geiger and proportional counters, ionization chambers and linear amplifiers that were essential to radiochemistry in the early 1940s. Dr. Kennedy began work on the Manhattan Project at Los Alamos Laboratory in March 1943 where he developed and tested the atomic bomb. President Harry Truman awarded Dr. Kennedy the Medal of Merit in 1946, the highest military award for a civilian. After his assignment at Los Alamos, Dr. Kennedy was named chairman of the Chemistry Department at Washington University in St. Louis and pioneered hot labs where tracer atoms were studied. Dr. Kennedy died in May 5, 1957 in Laude, Missouri. At the urging of Dr. Kennedy's family, the board of regents renamed the science auditorium at Stephen F. Austin State University the Joseph W. Kennedy Auditorium on January 23, 1971.
