Dora Jane Heineberg was born in
Philadelphia. The couple married after he had gained his PhD in 1941. Janson "never denied that she consciously sacrificed her career to raise children". She also collaborated as co-author with her husband on
The Story of Painting for Young People (1954) and
History of Art (1962).
History of Art entirely excluded women painters. Dora Janson's
From slave to siren (1971), an extensive catalog of a
Duke University Museum of Art exhibition on Victorian women's jewellery, related the jewelry to changing 19th-century ideals of feminine beauty and behaviour, reflected in
cameo portraiture. Janson died in
Devon, Pennsylvania. Her son Anthony Janson is also an art historian. ==Works==
