Jerzy Kazimierz Pajączkowski-Dydyński (19 July 1894 – 6 December 2005)[1] was a Polish veteran of World War I living in the United Kingdom.

Pajączkowski-Dydyński was born in Lwów (present-day Lviv, Ukraine), the capital of what became the Austrian province of Galicia.

Although technically part of Austria-Hungary, the Galician Polish enjoyed a "degree of autonomy in local government".

This unit, which contained Polish-American volunteers, had seen action in 1918 in the allied campaign in Alsace-Lorraine, fostering an acute sense of Polish identity among the troops.

[citation needed] When peace came, Pajączkowski-Dydyński elected to serve in the army of the newly proclaimed Republic of Poland guaranteed by the signatories to the Treaty of Versailles.

He became a lieutenant and staff officer under General Józef Haller in an infantry division, and took part in the 1920–21 Polish War against Soviet Russia.

In 1943, he moved to Edinburgh, translating and adapting British military regulations and manuals for the use of Polish units.

[citation needed] When the war ended in May 1945, Pajączkowski-Dydyński made Edinburgh his home as Lwów had been annexed by the Soviet Union.
