Economic effects of the world war upon women and children in Great Britain
by Irene Osgood Andrews, Margaret A. Hobbs
About the author
Margaret A. Hobbs is credited as co-author, with Irene Osgood Andrews, of Economic Effects of the World War Upon Women and Children in Great Britain, published by Oxford University Press in 1921.
That book examines how the First World War reshaped labor in Britain, especially by expanding women's industrial employment and changing the economic position of women and children. Modern library and archive records consistently point to this title as the main work connected with her name.
Beyond that publication credit, I couldn't confirm many personal biographical details from reliable sources during this search. Because the record is so thin, it seems safest to remember her as a researcher or writer whose surviving legacy is tied to an important study of wartime social and economic change.
