The threat of war meant that many of the women who registered at the Sorbonne in 1938 and 1939 did not stay. Blaess went out to Paris regardless, sharing the confidence of relatives and university staff that German aggression could be competently and swiftly repelled. She stayed at the lodging house, Les Marronniers, 78 rue d’Assas. The lodging house is still open to long-term and short-term tenants and visitors to Paris just as it was in the inter-war and the 1940s. See its web site  Les Marronniers and for a feature about it and its owner, Marie, see Marie et sa pension de famille
