Madeline M. Nevins, who did writing, editing and research for several organizations in the Washington area and retired from Booz Allen Hamilton in 2000, died Jan. 9 at Shady Grove Adventist Hospital in Rockville. She was 78.

The cause was a cerebral aneurysm, said her husband, Stephen B. Weiner.

Beginning in the mid-1970s, Dr. Nevins was an editor of religious books and worked at the IPA consulting firm, at the Association of American Medical Colleges and at Maximus, a government services contractor.

At Booz Allen Hamilton, she was a proposal writer and editor of the firm’s Web site, among other responsibilities. A certified French-English translator, she oversaw the Web site’s foreign-language content in seven languages, her husband said.

Sarah Elizabeth Nevins was born in Boston. She took the name Madeline Marie after becoming a Roman Catholic nun in the order of the Sisters of St. Joseph of Boston.

While serving as a nun and working as a teacher, she received a bachelor’s degree in French from Regis College in Weston, Mass., in the early 1960s, a master’s degree in French from Tufts University in Medford, Mass., in 1966 and a doctorate in medieval semiliturgical French literature, also from Tufts, in 1973. Her research scholarships included a Fulbright fellowship.

Dr. Nevins left the religious order in the early 1970s and taught at North Carolina Wesleyan College before settling in the Washington area in 1975. She was a longtime Kensington resident before moving to the King Farm community in Rockville in 2004.

She was a past member of Holy Cross Catholic Church in Garrett Park, where she served on the parish council and as a lector. She later was a lector at St. Mary’s Catholic Church in Rockville.

Survivors include her husband of 32 years, Stephen B. Weiner of Rockville, and two sisters.
