After her husband's death, she married Theodor Römpler in 1883, founder and head physician at the family-owned Sanatorium Görbersdorf (Waldenburg, Silesia).
[1] At the outbreak of World War I, Joël served as Landwehroffizier at the counterintelligence department of the Stellvertretender Generalstab in Berlin.
In 1915, he fought determinedly, but unsuccessfully, against the execution of British citizen Edith Cavell, who had been found guilty of treason.
[1] By then, the Empire had been replaced with a republic but Joël continued to work at the Reichsjustizministerium (Ministry of Justice) and in early 1920 became Unterstaatssekretär (under-secretary) and on 1 April 1920 Staatssekretär.
During the Kapp-Lüttwitz Putsch of March 1920, Joël organised a conference of the ministerial under-secretaries and then went to Kapp to deliver their unanimous declaration against the putschists and in favour of the legitimate government.
Joël was particularly close to Gustav Radbruch, Kuno von Westarp, Heinrich Brüning and Wilhelm Kahl [de].
The cabinet resigned in June 1932 and Joël then refused the offer by Franz von Papen to join its successor, since he did not want to be a party to the planned lifting of the legal ban on Sturmabteilung and Schutzstaffel, which he had earlier co-signed into law.
