Epaminondas George Aristotle Alexander Stassinopoulos (January 17, 1921 – May 16, 2022) was an ethnic Greek, German-born American astrophysicist, author, and Resistance member against the Nazis occupying Greece during

Career
Stassinopoulos joined NASA's Goddard Space Flight Center (GSFC) in Greenbelt, Maryland, in 1961, after graduate studies in Mathematics and Physics
Stassinopoulos was the principal investigator in 23 original research projects for NASA and he was the author or co-author of 146 papers and articles in peer-reviewed scientific, technical, and engineering journals and books; 31 special official NASA publications; and 154 NASA Technical Study, Research, and Analysis Publications in the field of
Stassinopoulos micro-miniaturized two prototype space-qualified and pedigreed radiation monitors/dosimeters/spectrometers into a single pill-box sized hybrid instrument, a Pulse Height Analyzer (PHA) called the Miniature High-LET Radiation Spectrometer, weighing less than 90 grams, and was awarded a US Patent (No. 7465926 B2) on December 16, 2008 for his "Device system and method for a miniaturized radiation spectrometer." The instrument has been used for flight measurements on commercial jets, the Concorde, and the STS-95 Host Mission. Stassinopoulos' PHA instrument is currently collecting data on the NASA DSCOVR satellite, which was launched on February 11, 2015.
After 45 years of service to NASA, Stassinopoulos retired to Emeritus status and continued to study and analyze space radiation data from the PHA. At 95 years of age, he authored a NASA Technical Publication (STI#25740 TN28435-Stass-2015) with fellow NASA scientists MA Xapsos and CA Stauffer, "Forty-Year 'Drift' and Change of the South Atlantic Anomaly (SAA)", making him one of the oldest publishing research scientists and authors in NASA's history.
Personal life and death
Stassinopoulos married Eftichia "Effie" Pappaioannou, a philologist and archaeologist, on 16 July 1950. They had one daughter and three grandchildren. Effie died in 2013.[1] Stassinopoulos turned 100 in January 2021, and died in Los Angeles on May 16, 2022, at the age of 101.[6]
Awards and honors
During his career, Stassinopoulos received numerous awards, including the IEEE Radiation Effects Award (2000);[2] the APOLLO-XI Achievement Award; a Faculte des Sciences medal from the Academie de Montpellier, France; the NASA Exceptional Service Medal in 1992, and the GSFC "Award of Merit" in 1999.
