Glenn Stagg spotted talent in young colleagues and coworkers and populated the computer applications department with young coworkers who became industry leaders in their own right. As the demand for Glenn’s talent began to go beyond the environs of the AEP, Glenn formed the power engineering consulting company (Stagg Systems, Inc.) in 1970 and remained its president and chief executive officer until 1992. After his retirement from Stagg Systems in 1992, he became a consultant to the World Bank and later served as an energy specialist and an independent consultant to various power engineering companies throughout the world.
Apart from the Stagg–El-Abiad book, Glenn authored or coauthored over 30 technical papers on various aspects of computer applications in electric power engineering that are among the classics of the genre. Glenn was elected a fellow of the Institute of Electrical and Electronics Engineers in 1992 and was elected to the National Academy of Engineering in 1997. He received an Honorable Mention Award for Outstanding Young Electrical Engineer by the honorary society Eta Kappa Nu in 1957.
Glenn enjoyed art and history and he collected antiques. He truly enjoyed working on power system engineering problems, and he enjoyed the opportunities it gave him to do the things he enjoyed, such as traveling and meeting new and interesting people. He served during World War II and became a collector of military memorabilia also. When he was younger, he played football, and it remained his favorite sport throughout life. He was a devoted fan of the Brooklyn Dodgers and of the New York Jets. He enjoyed working on his home and did carpentry work and landscaping in his spare time. Glenn had a younger brother Ronald who was a doctor of biology and a professor at Hartwick College in Oneonta, New York. Ronald passed away several years ago of cancer. Ronald had five children, who are scattered throughout the United States. Glenn is survived by his wife, Oksana; his first wife, Eleanor; and their three daughters, Joan, Janet, and Virginia; two grandsons, John and Scott; and three granddaughters—Jennie, Janet, and Katherine.
