He graduated from Corona High School in 1945 and from Chaffey Community College at Ontario in 1947. He earned a Bachelor degree in Mathematics from the University of California at Berkeley in June 1949, and married Peggy (Pritchard) the following month at Corona.
- Loren was the first local member of the scientific staff at the U.S. Government laboratory in Norco when it relocated from Washington D.C. in 1951.
- In 1959 Loren moved with his young family to Berkeley, where he earned his Ph.D. degree in Applied Mathematics in 1965. He worked for Lawrence Berkeley Laboratory till 1981, when he was appointed Professor of Computer Science at University of San Francisco. Meanwhile, he served for more than 20 years as a U.S. delegate to the international committee for Fortran language standardization, and became slightly famous as a Fortran language textbook author. He retired in 1993, and now lives with Peggy at San Jose, where his three principal hobbies are (in decreasing rank): eight grandchildren, Meissner family genealogy, and writing books for History Press.
