Aleksander Bychowiec

Aleksander Bychowiec of Mogiła (Russian: Александр Иосифович Биховец) was a Russian-Polish noble and an amateur historian of the Russian Empire from the Grodno Governorate.

He is best known as the discoverer (and the name-sake) of the so-called Bychowiec Chronicle, a set of 16th-century texts related to the history of the Grand Duchy of Lithuania.
