Tadeusz Jerzy Gebethner (18 November 1897 – 14 October 1944) was a Polish soldier, insurgent, bookseller, and footballer. From 1914 to 1925 he was an active player and captain of the Polonia Warsaw team; later he worked in his family bookstore and publishing business (Gebethner i Wolff [pl]). Tadeusz Gebethner fought in the Polish–Soviet War and Polish September Campaign. Becoming an officer of the Home Army after the invasion, from 1942 he sheltered a Jewish family in his home in Warsaw during the German occupation. A participant of the Warsaw Uprising, he was critically wounded and taken prisoner to Stalag-XIA, where he died from the same injuries on 14 October 1944. For his wartime activities, he was recognised as one of the Polish Righteous Among the Nations in 1981.

After World War II began with the German invasion of Poland in September 1939, as a lieutenant of the reserve Gebethner was mobilised and joined the 102 Reserve Ulhan Regiment [pl]. Following the Soviet invasion of Poland which occurred shortly afterward, he took part in the Battle of Grodno. Shortly thereafter, together with most of his unit, he crossed the Polish-Lithuanian border and was interned in the camp in Rokiškis. Gebethner escaped from the camp and moved to Wilno (now Vilnius, Lithuania), where he became involved in the Polish resistance (Union of Armed Struggle) and organised more escapes from the Rokiškis camp (following the Soviet occupation of the Baltic states, many of the Polish officers still there perished in the Katyn massacre). In 1941, he returned to Warsaw and joined the Home Army (Armia Krajowa).^[2]

In the years 1942 to 1944, he helped to save a Jewish family of three (the Abrahamers), for whom he arranged shelter in his home and other support, including arranging for fake documents (Kennkarte), medical care, and bribing the Blue Police when the family was discovered. Eventually he was able to arrange their evacuation to Hungary. The Abrahamer family survived the war thanks to this.^[2][4][5][6] He also convinced the Home Army not to execute Józef Retinger.^[2]

During the Warsaw Uprising he served in the 3rd Armored Battalion (the Golski Battalion [pl]) of the Home Army. He was seriously injured in the fighting, losing an arm and a leg. After the capitulation of the Polish insurgents, he was interned in Stalag XI-A Altengrabow in the Magdeburg area. He died in a nearby hospital on 14 October 1944, at the age of 46, as a result of wounds received during the Uprising. He was buried there, but the cemetery was destroyed by the Red Army during post-war military base construction.^[2][3] Later he received a symbolic grave in the Varsovian Powązki Cemetery.^[7]

He was promoted to rotmistrz (cavalry captain) either on 11 September^[2] or posthumously.^[3]

For his wartime activities, in 1981 he was recognised by Yad Vashem as one of the Polish Righteous Among the Nations.^[2][4][5][6]

In 2022, his story was used in educational materials prepared by the British Holocaust Educational Trust for the Premier League youth.^[8]
