A Holocaust survivor, he was hidden by Catholic clergy in Kielce, took part in the Warsaw Uprising and after captivity in a German POW camp, resumed the final years of his career in the United Kingdom.
Original members of the group included artists such as Fryderyk Pautsch, Adam Ballenstedt, Bronisław Bartel, Wiktor Gosieniecki, Stanisław Jagmin, Lubelski, Władysław Roguski, Stefan Sonnewend and Jan Jerzy Wroniecki.
[8] At the 1927 Polish Sculpture (Rzeźba Polska) exhibition, he presented two works Hygieia handing down her knowledge in reconstituted stone, and a bust of Major General Thaddeus Unrug.
[10][11] When WWII broke out in 1939, he was in great peril as a Jew, and was assisted by the Bishop of Kielce, Czesław Kaczmarek who gave him sanctuary in his diocese, and with whom he corresponded to the end of the latter's life.
[12] During the German occupation of Poland he joined the Armia Krajowa – Home Army resistance - and took part in the Warsaw Uprising, following which he was incarcerated in a Nazi POW camp.
Lubelski created many sculptures for public buildings and churches, perhaps his best known being the Grade II* Listed Polish War Memorial at Northolt Aerodrome, west London, unveiled in 1948.
[17] Lubelski is believed to be the author of the tomb of Captain Czesław Pobóg-Pruśnikowski (1893-1924) Virtuti Militari, commissioned by his regiment for the Fort Winiary cemetery in Poznań in 1924.
At the historic Lutheran Cemetery in Warsaw, Lubelski is the author of two extant projects: the bronze relief portrait of Eugenia Prochnau and the funerary statue of Franciszek Sokal (1881-1932), Polish delegate to the League of Nations.
[20] One of his only funerary monuments in London consists of a maiolica plaque of Christ praying in Gethsemane, set in a concrete chapel-shaped headstone on the grave of Dr. Antoni Kutek at Brompton Cemetery.
