Stuart H. Rakoff, a policy analyst and principal of the Reston, Va.-based consulting firm Rakoff & Associates from 1994 until 2013, died Jan. 6 at his home in Reston. He was 69.

The cause was amyotrophic lateral sclerosis, or Lou Gehrig’s disease, said his wife, Roz Rakoff. He documented his 16-month battle with the disease regularly in a blog.

Dr. Rakoff’s firm advised health-care organizations, the Defense Department and other clients on policy analysis, organization effectiveness and human resources policy. He retired in July 2013.

Earlier, he was an associate at the Lewin Group of Falls Church and the Jefferson Consulting Group in Washington. He also served as director of manpower planning and analysis for the office of the secretary of defense from 1979 to 1984.

Stuart Harvey Rakoff was born in Providence, R.I., and was a 1965 graduate of Colby College in Waterville, Maine. He received a master’s degree in 1967 and a doctorate in 1969, both in political science, from the University of Minnesota.

He taught political science at Binghamton University in New York before settling in Reston in 1974.

Dr. Rakoff co-facilitated a men’s anger management group at the Northwest Center in Reston and volunteered with Inova Fairfax Hospital’s CATS (Comprehensive Addiction Treatment Services) Program.

In 2013, he received the Fairfax County Volunteer Service Award and the Joseph L. Ritchey Community Service Award from YMCA Fairfax County Reston.

He was a board member of the Fairfax County Police Officers Retirement System and the Greater Reston Art Center. He was also a past chairman of the board of the nonprofit group Cornerstones (formerly Reston Interfaith), which advocates for the homeless and others in need.

Survivors include his wife of 47 years, Roz Itskowitz Rakoff of Reston; a son, Simon Rakoff of Reston; his mother, Ruth Rakoff of Springfield, Mass.; a brother; and two grandchildren.
