George E. Mattingly Jr’s obituary (1938-2025) George E. Mattingly Jr. passed away on January 24, 2025 in Washington DC, while residing at Knollwood, not far from where he grew up on Nebraska Avenue. He was born in Washington, DC of an old family whose first member registered in the census records in 1810. But his family was in the city before then. He continued this tradition with his birth on August 9, 1938 in Providence Hospital to George E. Mattingly Sr and Mabel Bateman Mattingly, both Washingtonians. George Jr went to Blessed Sacrament school from 1943 to 1952 when he then went to Priory School (now St. Anselm’s Abbey School) and graduated in 1956. Throughout his life he participated in the graduate-student baseball games playing third base and lectured to the students there on Career Day. Later he studied in the Department of Mechanical Engineering at the University of Maryland from 1956 to 1963, working Summer at the U. S. Navy ‘s David Taylor Model Basin. In the process he also took his BS ad MA degrees at the University of Maryland. After such a grounding he went to Princeton University, took his PhD there in 1969 and married in that year to Cathrine Schulz of Trinity College, Washington, He taught at Princeton as an Assistant Professor of Hydraulics (known also as Fluid Dynamics) at that institution from 1969 to 1975. He was especially directed and benefitted from the instruction of Prof. Francis R. Hama with whom he worked at the University of Maryland before Hama came to Princeton. In 1975 he took a position at the National Institute of Standards and Technology (NIST), formerly known as the Bureau of Standards. He worked there for more than 25 years, living in Bethesda, Maryland. In this position, George E. Mattingly Jr., as an overly short computer [EMedEvents] biography further specified, was responsible for the “US national standards for the flow of water, hydrocarbon liquids, gas, airspeed, and liquid volume and density, and the dissemination of these standards via calibration services and proficiency testing programs for US industry, academia, and other government agencies. He retired from NIST in 2004. Through these years he served on the paper standards writing committees - both national (ASME) and international. Additionally, he served as an NVLAP Accreditor for flow measurements. Before his retirement, he served as the Chairman of the Subcommittee writing the ASME paper standard on Flow Measurement Uncertainty.” In 1993 he received the Engineer of the Year award from The Department of Commerce and during his career published more than 100 articles, reports and book chapters on his subject. George and his wife produced two daughters, Virginia and Kate, who made them very proud and who survive him. In 2023 George and his wife moved to Knollwood, a retirement facility for government workers, in Washington DC and resided there until he passed. He was also pleased at his participation at the Cosmos Club of Washington to whom he often lectured. He is survived by two brothers, Paul of Raleigh NC and James of Washington DC, and a dear sister, Lynn Streckfus of Glen Arm, Maryland.
