Stefan Napierski, actually Stefan Marek Eiger (born 15 March 1899 in Warsaw, died 2 April 1940 in Palmiry) was a Polish poet of Jewish origin, translator and essayist, in the years 1938–1939 publisher of the bimonthly Ateneum [pl].

As a young man, Napierski converted to Roman Catholicism and took a Polish-sounding nom-de-plume.

Despite being gay (the fact was an open secret of literary circles), he was married to Irena Tuwim in the years 1922–1935.

[3] Thanks to Napierski's intercession, Jarosław Iwaszkiewicz was given the position of the secretary of the Marshal of the Sejm.

Taken from Pawiak prison,[4] he was shot in the Palmiry massacre along a group of significant representatives of the Polish intelligentsia living in Warsaw.
