Margaret B. Blake, a former substitute teacher at the private Beauvoir school in Washington, died Feb. 11 at a retirement home in Santa Barbara, Calif. She was 103.

The cause was congestive heart failure, said her son Stephen Rickert.

Margaret Eleanor Bradley was born in Evanston, Ill. Her father, Luther Daniels Bradley, was an editorial cartoonist for the Chicago Daily News. She was a 1932 graduate of Bryn Mawr College in Pennsylvania, where she sang in the glee club. She then moved to Washington and became a homemaker.

She worked in the State Department’s passport office from 1960 to 1966. She later was a librarian in Mackinac Island, Mich., and Sharon, Conn., before returning to the Washington area in 1978.

She then was a substitute teacher at Beauvoir for a decade before settling in Santa Barbara.

She was a volunteer counselor with the Families and Children in Trouble hotline, visited terminally ill patients at the Washington Home and sang with the Cathedral Choral Society. She was also active in the Moral Re-Armament movement.

Her first husband, Van Dusen Rickert Jr., died in 1950 after 15 years of marriage; their son, Philip Rickert, died in 1973. Her second husband, Rev. Howard Carson Blake, died in 1996 after eight years of marriage.

Survivors include three children from her first marriage, Jonathan Rickert of Washington, Stephen Rickert of La Canada, Calif., and Annie Shields of Rome, Ga.; two stepchildren, Alice Chaffee of Carpinteria, Calif., and Peter Blake of Aurora, Calif.; seven grandchildren; and three great-grandchildren.
