W. Elst at the European Southern Observatory. Edith (Louisa) Cavell (1865-1915) was an English nurse who in 1907 was appointed to the Berkendael Institute in Brussels, where she greatly improved the standard of nursing. In 1915 she was sentenced to death and shot by the Germans, because she had helped Allied soldiers escape from Belgium.
