Elsie Sanders Rosenberg, 98, a former teacher in the D.C. public school system who was active in the Red Cross Braille transcription program for many years, died Saturday at Georgetown University Hospital. She had pneumonia.

Mrs. Rosenberg was born in Germany and came to the United States when she was 3. She and her family settled in Washington and she lived in the city for the rest of her life. She graduated from the old Central High School, George Washington University and the old Wilson Normal School.

In the early 1900s, she joined the D.C. school system as a physical education teacher. She spent most of her career at Central High.

During World War I, Mrs. Rosenberg was an aide in physical rehabilitation programs at a military hospital on Long Island, N.Y.

In the early 1930s, she resigned from her teaching position to marry Maurice Rosenberg, president of the old Bank of Commerce. In the mid-1930s, she became head of the Braille transcription program for the blind run by the D.C. chapter of the American Red Cross. She continued this work until the 1960s.

Mrs. Rosenberg's husband died in the early 1940s. Survivors include one sister, Mrs. Henry King, of Washington, two step-grandchildren, and two step-great-grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to a charity of one's choice.
