Maciej Aleksy Dawidowski codename: Alek, Glizda, Kopernicki, Koziorożec (3 November 1920, in Drohobycz – 30 March 1943, in Warsaw, Poland) was a Polish scoutmaster (podharcmistrz), Polish Scouting resistance activist and Second Lieutenant of the Armia Krajowa during the Second World War.

[1] Dawidowski is a main character in the books Kamienie na Szaniec by Aleksander Kamiński, and Rudy, Alek, Zośka by Barbara Wachowicz.

Following the German occupation of Warsaw in late September 1939, the senior Dawidowski was arrested in November 1939, and in December 1939 the father was shot in the Sejm Gardens.

The Polish underground army designed a plan to rescue him called "Operation Arsenal".

During the attack, he was seriously wounded in the stomach by fire from Germans in the gate house where Bytnar was held.
