Gabriele Sieg, 95, who retired in 2001 as head librarian of the German School in Potomac, died Jan. 12 at an assisted living facility in Boston.

She had complications from a fall several weeks earlier, said her daughter, Alexandra Pierce.

Mrs. Sieg worked at the German School library for about two decades. In addition to her duties cataloguing books and assisting students and scholars with research, she organized a number of exhibits.

Before working at the German School, she was a cataloguer and classifier with the Byzantine Studies program at the Dumbarton Oaks Research Library and Collection in Georgetown.

Gabriele Margarethe Lutz was born in Freiburg, Germany. She immigrated to the United States in 1958 and became a U.S. citizen in 1963.

Mrs. Sieg was a past president of the American Goethe Society of Washington. In the 1990s, she received a prestigious cultural award from the German government.

Mrs. Sieg lived in Potomac for three decades before moving to Santa Barbara, Calif., about five years ago. She had lived near her daughter in Boston for about the past six months.

Her first marriage, to Emil Liebmann, ended in divorce. Her husband of 63 years, Helmut Sieg, died in 2011. Survivors include a daughter from her first marriage, Alexandra Pierce of Boston; two grandchildren; and three great-grandchildren.
