She was born in London in 1903, the daughter of an architect, and studied at
Hornsey School of Art and
Regent Street Polytechnic. Her preferred medium was watercolour, and she admired the work of
Beatrix Potter,
Kate Greenaway and
Arthur Rackham. She took an interest in the countryside, and enjoyed reading and gardening. In the 1930s, Boswell began drawing adventure picture strips for the comics of
Amalgamated Press. Her longest running feature was
Strongheart, based on the canine film star of the same name. The series had been originated by G W Backhouse in 1927, and Boswell worked on it from 1939, first for the weekly comic
Crackers and later for
Jingles. ==Books==
