Kazimierz Leski, Polish engineer and pilot (b. 1912)
Kazimierz Leski, nom de guerre Bradl (21 June 1912 — 27 May 2000), was a Polish engineer, co-designer of the Polish submarines ORP Sęp (1938) and ORP Orzeł, a fighter pilot, and an officer in World War II Home Army's intelligence and counter-intelligence.

He is credited, during World War II, with at least 25 journeys across German-held Europe, usually in the uniform of a Wehrmacht Major General.

After the war, he was imprisoned by Poland's communist authorities. He spent seven years on death row before being rehabilitated in 1956. He then resumed work as an engineer.
