On 21 April 1985, Yad Vashem recognized Spaak as Righteous Among the Nations,[1] for helping to smuggle several Jewish children to safety, by providing them with ration cards and clothing.

Living in Paris with her husband and two children, Lucie known affectionately as Pilette and Paul-Louis as Bazou, she enjoyed a life of luxury and prestige as one of the city's leading socialites.

The network became so successful, even infiltrating the German military intelligence service Abwehr, [citation needed] that the Nazis set up the "Red Orchestra Special Detachment" (Sonderkommando Rote Kapelle) to destroy it.

In early 1943, she was part of a group that saved 163 Jewish children who were about to be deported from the Union générale des israélites de France (UGIF) centers.

Captured members were brutally tortured and several broke, divulging network secrets that, over the ensuing eighteen months, allowed for more than 600 people to be arrested, including Suzanne Spaak in Paris.
