He performed songs and monologues by famous poets and songwriters including
Marian Hemar,
Jerzy Jurandot,
Antoni Słonimski,
Julian Tuwim and
Andrzej Włast. He made his first movie in 1927 (
Ziemia obiecana) as part of a comedy duo, "Lopek and Florek," with
Adolf Dymsza; they made several more movies together including
Janko Muzykant; Ułani, ułani, chłopcy malowani, and
Co mój mąż robi w nocy? (What does my husband do at night?) In 1935 he starred in the film
ABC miłości. He was engaged at the cabaret by his cousin Julian Tuwim. He performed in theaters, kleynkunst, and cabarets including Morskie Oko, Banda, Cyganeria,
Cyrulik Warszawski, Wielka Rewia, and in 1939 he founded his own theater, the Ali Baba. "in the cabarets, a new genre of entertainment—the Jewish joke, monologue or sketch known as szmonces—rose to prominence. The
szmonces, inevitably characterized by a more or less subtle
żydłaczenie, at its best turned the pretentious Jewish assimilator or the harried Jewish tradesman into universally accessible symbols of the dislocations of modern life; at its worst, it became vulgar antisemitic caricature. The performer Kazimierz Krukowski (1902–1984), known as Lopek, was among those acclaimed as a specialist in the genre." During the
Second World War he appeared in one of the cabarets in the
Warsaw ghetto. He fought in the
Soviet Union and subsequently lived in
Britain, the
United States, and
Argentina, where he ran the
El Nacional theater. ==Books==
