Dawid Wdowiński was born in 1895 in Będzin. He studied at universities in Vienna, Brno and Warsaw, and became a psychiatrist. Wdowiński was a member of the right-wing organization Hatzohar, which was founded in Paris in 1925. Before World War II, Wdowiński gave up psychiatry through the influence of Ze'ev Jabotinsky, who urged him to devote himself fully to the cause of Revisionist Zionism. Wdowiński became a chairman of the Revisionist Zionist party called Polska Partia Syjonistyczna.
After the war, Wdowiński settled in the United States. Meanwhile, eyewitness accounts of the Warsaw Ghetto uprising were filtered through testimonies of former members of the left-leaning ŻOB. These accounts diminished both the roles and the importance of the ŻZW and Wdowiński. One such writer, Israel Gutman, was an activist in Hashomer Hatzair. Guttman's perspective continued in authoritative citations of Barbara Engelking and the Polish Center for Holocaust Research, who described Wdowiński as a senior activist in the Polish branch of Jabotinsky's New Zionist Organization; i.e. the "revisionist leader in the ghetto attributes himself in command of the fighting organisation of this political movement." Another ŻOB fighter wrote, "The Revisionists had seceded from the World Zionist Organization; and before the war, all socialist movements, including the Zionists, saw them as the Jewish ebodiminent of Fascism." Wdowiński candidly noted the pro-Soviet political orientation of the leftist Jews following the Soviet invasion of Poland: "The second, the confused political orientation, was largely because many Jewish leaders were reared in the spirit of the Russian Revolution, and they thought they could translate the ideas of the class struggle into Zionist terms." In 1961, Wdowiński served as a witness at the trial of Adolf Eichmann in Jerusalem. The situation with the historical record led Wdowiński, in 1963, to publish his own memoir, And We Are Not Saved, in which he writes about his involvement with the ŻZW and the Warsaw Ghetto uprising. Wdowiński was fiercely opposed to Jewish collaboration with Germany inside the ghettos, or any post-war reconciliation with them. This theme pervades his memoirs as well as his correspondence.
