Adam Jozef Aleksander Epler (born December 1, 1891, in Lwów, Austrian Galicia; died October 24, 1965, in London) was a Colonel of Artillery of the Polish Army, posthumously promoted to Generał brygady. Epler had a wife Zofia (née Murczynska) and son Zbigniew (born 1919).
Epler, who had one son Zbigniew (born 1919), was raised in an affluent family: his father Edward was a railroad engineer and deputy mayor of the city of Lwów. In 1909, he graduated from Classical Gymnasium in Chyrów, and began studies at Lwów University. In 1912, Epler was drafted into the Austro-Hungarian Army, serving at XI Artillery Brigade, and graduating from School of Reserve Officers. On May 1, 1915, he was promoted to Subcolonel (podporucznik). During World War I, he fought on the Italian Front, and in 1918, he completed artillery course for officers, which took place at Trento.
After the collapse of Austria-Hungary, Epler returned to former Austrian Galicia and joined the newly created Polish Army. In mid-November 1918, he was named commandant of an artillery battery of 1st Kraków Field Artillery Regiment. Together with the regiment, he fought in the Polish–Ukrainian War and Polish–Soviet War. In 1920, he was transferred to 3rd Legions Field Artillery Regiment.
After the Polish–Soviet War, Epler completed a military training course in Toruń, and was promoted to major. In 1922–1929, he served as artillery officer in the garrison of Zamość, where 3rd Legions Infantry Division was stationed. He was highly praised by General Stanislaw Kwasniewski, who at that time commanded the 3rd Division.
