Jerzy Kazimierz Pajączkowski-Dydyński (19 July 1894 – 6 December 2005) was a Polish veteran of World War I living in the United Kingdom. In 1915, he was conscripted into the Austro-Hungarian army, and he later fought for Poland, reaching the rank of colonel. Upon the German invasion of Poland that triggered World War II in 1939, he escaped with his family to Romania, then France and finally England after France capitulated to Germany in June 1940. In later life he worked as a gardener in Scotland before moving to Cumbria with his daughter. He died at a nursing home, aged 111 years and 140 days, and had been Britain's oldest living man.
