Obituary: James A. Grundl Mar. 15, 1929 – Dec. 8, 2022

James Arlington Grundl, age 93, died peacefully on December 8, 2022, in Wauwatosa, Wisconsin. Born March 15, 1929, in Milwaukee to Herman A. and Irene M. (Martina) Grundl, both of Milwaukee, he graduated with a BS degree from Marquette University and an MS degree from the University of Wisconsin-Madison, both in physics. In 1952 he married Elaine Ellen McGowan of Greenleaf, Wisconsin, and they moved to Los Alamos, New Mexico, where he worked as a nuclear physicist for the Los Alamos Scientific Laboratory. He earned a PhD degree in physics from the University of New Mexico in 1958. In 1969, he moved to Gaithersburg, Maryland, where he worked as a nuclear physicist for the National Bureau of Standards until easing into retirement in the mid-1990s. In May 2021, Jim and Elaine moved to Wauwatosa, Wisconsin. A resolute Roman Catholic, Jim ever pondered the interaction of faith and science while observing the behavior of nuclear reactions and developing international neutron flux standards. He was supported by his devotion to St. Therese of Lisieux, kinship with Charlie Brown, and attentiveness to A Prairie Home Companion.

A funeral service was held December 22, 2022, at St. Pius X in Wauwatosa, after which he was entombed in Holy Cross Cemetery & Mausoleum above Elaine, who died May 30, 2021. He is survived by his brother Daniel J. Grundl (Springdale, Arkansas), his sister Barbara A. Grundl Murray (Sauk City, Wisconsin), and his three children, Timothy (wife Barbara), Peter, and Therese and two grandchildren, Katherine and Nicholas Grundl.
