Sister Emily George, 49, a former vice president of the Sisters of Mercy of the Union, an order of Catholic nuns in Silver Spring, was killed in an automobile accident Dec. 6 when her car skidded on an icy road into the path of a truck near Cassopolis, Mich.

She was a visiting scholar at the University of Notre Dame at the time of her death.

A spokesman for the Cass County sheriff's department said Sister George was going east on Michigan Route 60 in a snowstorm when she lost control of her automobile. He said the driver of the pickup truck was not injured.

Sister George was born in Grand Rapids, Mich., and graduated from Mercy College in Detroit. She earned master's and doctoral degrees in history at St. Louis University.

She was president of Mercy College and the associate director of Women in Transition, a shelter for battered women in Detroit, before moving to Silver Spring in 1980. She moved to Notre Dame, Ind., earlier this year.

She was a member of the boards of Mercy College and the Sisters of Mercy Health Corp. She had written several political biographies.

Survivors include a sister, Helen Smith, of Treasure Island, Fla.
