From 1942–1943, Reichmann worked for the BBC’s German listening service, after which she became the Director of Research at The Wiener Library. There she led an ambitious effort to record Holocaust survivor testimonies. Over seven years, with financial support of the Jewish Claims Conference Reichmann and her team gathered reports from refugees and survivors in Britain and abroad. The project gathered more than 1300 reports in seven different languages.
Reichmann belonged to the Belsize Square Synagogue, where she received numerous honours for her work. She died in London in 1998.
