David Lawrence Bongard, an author and editor who wrote widely on military matters, died March 31 of congestive heart failure at his Alexandria, Va., home.
The former Severna Park resident was 51.
Mr. Bongard was born in Summit, N.J., and spent his early years in Murray Hill, N.J., and Cinnaminson, N.J., before moving to Severna Park with his family.
After graduating from Severna Park High School in 1977, he entered the Honors Tutorial College at Ohio University, where he earned a bachelor's degree in history in 1980. He then earned a master's degree in history in 1982 from the University of Maryland, College Park.
He worked for several years at the National Archives in Washington, and later taught history and Civil War history at Potomac College's Washington and Herndon, Va., campuses until recent months.
He was also a co-author with Trevor N. Dupuy and Curt Johnson of "The Harper Encyclopedia of Military Biography," which has evolved into eight editions since its first publication in 1992.
Another book he co-authored with Mr. Dupuy and Richard C. Johnson was "Hitler's Last Gamble: The Battle of the Bulge, December 1944-January 1945," which was published in 1994.
"He enjoyed reading and researching immensely, and spent many hours in the archives," said his mother, Marilyn R. Bongard, of Severna Park.
Mrs. Bongard said the cause of her son's heart failure was diabetes, which he had had for the past 41 years.
Mr. Bongard was a member of Woods Memorial Presbyterian Church in Severna Park where services were held Wednesday.
There are no other survivors.
