Lewis V. Spencer

Physicist

Lewis V. Spencer, 80, a physicist with the old National Bureau of Standards, died Nov. 11 at a nursing home in Midlothian, Va. He had dementia.

Dr. Spencer was affiliated with the Bureau of Standards (now the National Institute of Standards and Technology) from 1948 to 1984. He specialized in the study of radiation transport and radiation shielding, or how to protect people from nuclear fallout.

His work was used in guidelines for federal buildings. He was well known in his field and was the co-author of the book "Structure Shielding Against Fallout Gamma Rays From Nuclear Detonations" (1980).

From 1957 to 1969, he taught physics and mathematics at Ottawa University in Ottawa, Kan. He retained his affiliation with the Bureau of Standards during that time, returning for a year (1960-61) to serve as acting chief of the Radiation Theory Section. He returned to the bureau permanently in 1969.

He chaired the scientific committee of the National Council on Radiation Protection and Measurements, which studied radiation exposures that would result from large-scale accidents or attacks. He was a scientific observer to NATO and led many panels and conferences on nuclear radiation throughout the country. He retired in 1984 and published his final major scientific paper in 1993.

Lewis Van Clief Spencer was born in Hillsdale, Mich. Because of a childhood accident, his right arm was amputated at the shoulder and his right leg at the knee. He became an exceptional one-handed typist, capable of typing 100 words a minute without error.

He graduated from Franklin College in Franklin, Ind., and received master's and doctoral degrees in physics from Northwestern University in 1946 and 1948, respectively.

He belonged to the Sigma Xi and Pi Mu Epsilon honorary societies and was the first recipient of the Gray Medal, awarded by the International Commission of Radiation Units and Measurements.

He lived in Kensington in the 1950s and in Gaithersburg from 1969 to 1984. He was a member of Wheaton Baptist Church. He lived in Hopkinsville, Ky., from 1984 to 2001, when he moved to Midlothian, near Richmond.
