An official publication of the Polish government-in-exile, March 1944, provides the following information, likely from the subject himself (brackets added showing his ages in the narrative):
"Jan Kwapinski (correct pronunciation: Kv-a-pin-ski), Deputy Prime Minister and Minister of Industry, Commerce and Shipping, son of a worker and a metal worker himself, has long been one of the most prominent figures in Poland's labor and political movement.
Born in Warsaw in 1885, his life reflects the turbulent history of the Polish patriotic revolutionary movement. From his early youth he took an active part in the underground organization. He joined the Polish Socialist Party in 1902 [17] and played an active role in the anti-Czarist uprising of 1905 [20]. When the revolt failed, Kwapinski made his escape to Cracow (then in Austrian Poland), where he continued his political activities. After his return to Russian Poland in 1906 [21] he took part in underground revolutionary organization. The following year he was arrested by the Czarist police and sentenced to 15 years hard labor. Having organized the prisoners' rebellion in the Lomza Prison, he managed to escape, but was caught and removed to Orel Prison, where he remained until 1917 [32], when the Russian Revolution set him free.
