Dennis N. Logan, 87, who retired in 1980 as deputy chief of the D.C. fire department and then spent more than 20 years chairing a Neighborhood Watch program in Southeast Washington, died March 2 of cardiogenic shock at Georgetown University Hospital.

The death was confirmed by his wife, Gloria Logan.

Mr. Logan joined the fire department in 1951 as a firefighter and rose through the ranks. He was promoted to battalion chief in 1973 and became one of the city’s first deputy fire chiefs in 1978. He retired from the administrative division.

Dennis Napoleon Logan was born in Rutherfordton, N.C. He was a Navy veteran of World War II.

He was a resident of Southeast Washington’s Hillcrest neighborhood. He helped launch the Neighborhood Watch program in his community, which received praise for its effectiveness at curbing crime and making the neighborhood a residential draw. The neighborhood’s first “night out” — part of a nationwide event to prevent outdoor and drug-related crime — was held in 1989 on Mr. Logan’s front lawn.

He was a past president of the Kiwanis Club in Northwest Washington, past treasurer of the Hillcrest Community Civic Association and a past board member of Boys and Girls Clubs of Greater Washington.

He was a member of St. Francis Xavier Catholic Church in Washington and served as coordinator of ushers. He was a past president of the Holy Name Society at the church. He was a founding member of the Washington Interfaith Network. His other memberships included the Knights of Columbus.

Survivors include his wife of 55 years, Gloria Ford Logan of Washington; three sons, Dennis G. Logan of Glen Allen, Va., Derek Logan of Gaithersburg and David Logan of Sterling; two sisters; eight grandchildren; and five great-grandchildren.
