actor, writer, translator, and head of a Polish theatrical family.

Żółkowski was born into a noble family and served in the army during the revolt of 1794. He made his acting debut in Warsaw in 1798, toured the country for four years, and then joined the National Theatre (Teatr Narodowy), where he was admired for his comedy roles, including Don Bartholo in The Barber of Seville by Pierre Beaumarchais and Arnolphe in Molière's School for Wives. He also wrote several original comedies, translated English and French plays, and edited humorous works, including “Momus” and “Potpourri.” His wife, Maria Ludwika Żółkowska (1790–1853), was a popular classical actress with the National Theatre.

Three of Żółkowski's children went on the stage, the most notable being his son Alojzy Gonzaga Żółkowski (1814–89), a highly respected actor and opera singer who spent most of his career at the State Theatres of Warsaw; his rich baritone voice and brilliant acting technique made him a success in such varied roles as Dulcamara in Gaetano Donizetti's L'elisir d'amore and Polonius in Hamlet. His daughter, the actress Alojza Żółkowska (1850–1921), continued the family tradition and married into another Polish theatrical family, the Ostrowskis.
