Settela Steinbach was captured in this famous photograph (the same shot can also seen at around the 7:16 mark of this footage) in 1944 as she was being moved in a train from a camp in the Netherlands to Auschwitz-Birkenau. Although her face was well-known, her name and connection to the Romani (specifically the Sinti people) was unknown until 1994; until then, she was assumed to be Jewish. 

Steinbach died in Auschwitz, along with nine members of her family and 23,000 Roma and Sinti, not long after her arrival there.
