Nan Hillman, who gave private piano lessons at her home in Silver Spring since the mid-1970s, died Feb. 27 at Montgomery Hospice’s Casey House in Rockville. She was 80.

The cause was complications from kidney disease, said her son, Richard Bucheimer Jr.

Claire Nanette Baker was born in Moscow, Pa. She received a teacher’s certificate from the Peabody Institute of Johns Hopkins University and moved to the Washington area in the late 1960s. She was a 1980 music graduate of the University of Maryland.

Mrs. Hillman was a member and monitor with the Washington Music Teachers Association and chaired many of the association’s piano competitions, including the Viola Hartman Piano Performance Awards in Washington and the Tselentis Bach Competition.

In the 1960s, she fought for the desegregation of the old Tivoli Theatre in Frederick, Md., and was involved with a tutoring program for children of migrant workers.

Her first marriage, to Richard Bucheimer, ended in divorce. Survivors include her second husband of 43 years, Erik Hillman of Silver Spring; four children from her first marriage, Richard Bucheimer Jr., David Bucheimer and Robert Bucheimer, all of Frederick, and Christine Allen of Annapolis; a sister, Audrey Chalk of Sterling, Va.; nine grandchildren; and three great-grandchildren.
