Mieczyslaw (also Miszyslaw) Nathanblut, born in Warsaw in 1882, was a musician and writer and also known by the pen names M. Natrowski and Animatus. He also worked as an editor and dramaturge at the publishing house Oesterheld & Co.
He lost the German citizenship he had acquired after the First World War again during the National Socialist rule, so that he became stateless.
He was friends with the artist Julius Hart and his daughter, the painter and graphic artist Margarete (Grete) Hart (1885-1971). They met around 1902 at the Neue Gemeinschaft in Schlachtensee. From 1935 onwards
Mieczyslaw Nathanblut and Grete Hart, who was not Jewish, were threatened by the "Blood Protection Law". Friends testified in her support that their relationship had long been purely platonic.
Mieczyslaw Nathanblut was deported to Riga shortly after his 60th birthday on the "9th Eastern Transport" on 19 January 1942 (deportation list sheet 29, no. 6584) and perished there.
