Mordka Mendel Grossman was born on 27 June 1913 in Gorzkowice, Piotrków Governorate, Russian Empire (today Poland).
He was born in Gorzkowice to a Jewish Hasidic family as a son of Szmul Dawid Grossman and Hanna.
In the 1930s he connected with the Jewish Theater in Łódź, picturing scenes of all the performed plays, as well as actors and actresses.
Grossman also hid a camera in his coat during the day, taking photographs of the living conditions in the ghetto.
Other photos taken by Grossman were found by one of his friends, Nachman (Natek) Zonabend; these photographs are now located in the Museum of Holocaust and Resistance at the Ghetto Fighters House in Kibbutz Lohamei Hagetaot, Israel, as well as Yad Vashem in Jerusalem.
