Leo Hecht, 85, a retired Army major and intelligence officer who became a professor of Russian at George Mason University, died Dec. 4 at the Woodbine nursing center in Alexandria after a heart attack. He had Alzheimer’s disease.

His death was confirmed by Lori Murphy, his guardian and conservator.
