Morris James "Tod" Slonim, 95, a retired Air Force Department mathematical statistician who wrote textbooks on statistical sampling, died June 2 at Inova Fairfax Hospital after a stroke.

In the 1950s and '60s, Mr. Slonim was the assistant for mathematical statistics to the director of data systems at Air Force headquarters at the Pentagon. He then spent four years on assignment for the U.S. Agency for International Development as senior statistical training adviser to the government of Turkey before retiring in 1969.

Mr. Slonim was the author of several books, including "Sampling in a Nutshell," which was published by Simon & Schuster in 1960.

In 1969, he moved from Silver Spring to Orlando, where he worked as a statistical consultant and, in later years, competed in races in the Golden Age Olympics. At 75, he set a U.S. record in a 5K race in his age group.

Mr. Slonim returned to the Washington area in 1998, settling in Falls Church.

He was born in Molczadz, Poland. He grew up in Malden, Mass., after his family immigrated to this country when he was 3 years old. He graduated from Harvard University, where he also received a master's degree in business administration in 1933.

Before he began his career as a statistician, Mr. Slonim worked as a packer in a candy factory and as a longshoreman unloading banana boats in Boston Harbor. At the start of World War II, he joined the Army Air Forces and was placed in charge of a meteorological research section. He also served with the Air Technical Intelligence Group of the Pacific Air Command.

At the end of the war, he briefly returned to civilian life. He was living in Bellevue, Neb., when the Air Force recalled him to active duty during the Korean War. He initially served with the 305th Bomb Wing at MacDill Air Force Base in Tampa and later was sent to Korea, Okinawa and Japan.

His military decorations included the Bronze Star.

In recent years, Mr. Slonim enjoyed poker games with a group of friends every other week, daily walks to the library and writing limericks.

Survivors include his wife of 58 years, Mary Angeline "Angie" Slonim of Falls Church; three children, Nancy Forbes of Belmont, Mass., Mark Slonim of Maui, Hawaii, and Michael Slonim of Falls Church; and six grandchildren.
