Jan Józef Więckowski nom de guerre Drogosław (July 25, 1923, in Warsaw, Poland – July 11, 2008, in Bryn Mawr, Pennsylvania, US) was a Sub-Scout Master in the Polish Scouting Movement, a 2nd Lieutenant of the Home Army and a Captain of the Polish Armed Forces, Polish resistance member during the Warsaw Uprising, both Chief and Chief of Security for the Second Company Rudy of Battalion Zośka, and a 1951 graduate of international economics from Stetson University.

Jan was the brother of Maria Więckowska, a courier for the First Platoon "Sad" of the Battalion "Zośka" murdered during the Warsaw Uprising.

Once PET merged with the Gray Ranks, Więckowski was assigned to the southern scouting team SAD-400, commanded by his former classmate Andrzej Romocki.

During the first month of the Warsaw Uprising, Więckowski fought alongside Battalion Zośka in Wola and the Old Town.

Więckowski participated in battles which helped hold back German forces, allowing Polish civilians and resistance fighters to evacuate and retreat from Warsaw.

On September 2, the hospital was liquidated by German and Ukrainian forces resulting in the murders of several injured Poles - including Maria Więckowska.

[1] During the liquidation of the "Miodowa 23 Hospital," several Greek Jews liberated previously by the Polish Resistance from Gęsiówka were also murdered by the Germans and Ukrainians.

[2] Upon being liberated from Oflag X-C by the British, Więckowski left for Meppen in May 1945 and joined the Polish First Armoured Division.

In January 1946, he moved to London where he served on the staff of the Home Army Historical Commission of the Polish Commander-in-Chief, led by General Tadeusz Pełczyński and Colonel Kazimierz Iranek-Osmecki.
