Francis John Lovas Ph.D

Francis J. Lovas, Ph.D, of Germantown, MD, passed away peacefully on March 20, 2026 at the age of 84. He was born on July 29, 1941 to Frank J. “Slim” Lovas and Ann Noonan Lovas in Cleveland, OH. While growing up as one of seven siblings together in Fairview Park, OH, he was commonly known as Frank, and his younger siblings recall his persistence and ingenuity. Frank was very good about saving money while working as a newspaper carrier, grocery store cashier, and summer employee at his father’s metalworks employer, Iron Fireman. He was mechanically inclined and repaired discarded items like bicycles and lawn mowers and put them to good use. He and his brother Mike built a treehouse in a neighbor’s yard and had endless hours of enjoyment there. He was the only of the seven children to own his own car in high school, which he repaired as well.

Ironically, he once wrote that he did not like school, but graduated in the top 10 percent of his high school class. He went on to the University of Detroit earning a bachelor’s degree in Professional Chemistry in 1963 and accomplishing Magna Cum Laude status. He then earned a Doctorate in Physical Chemistry from the University of California, Berkley, in 1968 and proceeded into a NATO postdoctoral fellowship at the Freie University of Berlin. At the University of Detroit, he received a scholarship to join the fencing team and achieved All American honors. He continued fencing at a high level for many years, joining clubs in San Franciso and Berlin.

In 1970, Frank entered a career at the agency now named the National Institute of Standards and Technology (NIST) in Gaithersburg, MD. He worked at NIST for over 50 years, building and leading a laboratory focused on research into microwave molecular spectroscopy and data application to molecular structure, inter and intramolecular forces, and interstellar chemistry. His work broadly impacted chemistry, physics, and biology by providing important information on how molecules and atoms form weak bonds with each other, such as the hydrogen bonds that are critical to the structure of proteins and DNA. For his contributions to his scientific field, he was awarded several honors over his career. In 1977, he was awarded the U.S. Department of Commerce’s Gold Medal, the department’s highest honor for distinguished and exceptional performance, and in 2015 was recognized in the NIST Gallery of Distinguished Scientists.

Other than his family, Frank loved his work above all else, and his relationships with NIST colleagues and the international scientific community were among the most important in his life. His former colleagues and collaborators remembered him as a generous mentor, and always humble about his contributions, despite his status as an important and highly regarded researcher in radioastronomy. Through his compendium of over 300 publications, his research provides the scientific community with crucial evaluated data on the rotational spectra of molecules used to search for and detect molecules that exist (or might exist) in interstellar molecular clouds, from which stars, planets, in rare cases life are formed.

He married Paula-Marie Layng in Berlin, Germany in 1970, and they had one son, Daniel Layng Lovas, born in 1977. Frank and Paula-Marie later divorced and he remarried to Hong Xue in Maryland in 1999. Together, they shared 30 loving and rewarding years together in Bethesda and Germantown.

Frank enjoyed working around the house/yard, reading mystery and detective novels, and watching films. He will be remembered as a skilled fencer, a lover of grilling dinners in the backyard year-round, and for his devotion to his family, including helping to care for his aging mother-in-law and father-in-law in his later years.

Francis J. Lovas, Ph.D, is survived by his wife, Hong, his son, Daniel (Julie), and a grandson, Ryan, as well as his siblings, Mary, Michael, Elizabeth, and Kevin. Visitation will be held at Mother Seton Catholic Church at 19951 Father Hurley Blvd, Germantown, MD on Friday, March 27, from 10 - 11 AM, followed by funeral and burial services.
