Walter was the youngest brother of Liese Meitner (1878-1968), the Austrian physicist who worked on radioactivity and nuclear physics and was part of the team that discovered nuclear fission. Lotte Meitner-Graf started a photography studio in Vienna around 1920, and worked from that city until 1938. Her clients were artists, musicians and scientists. Her studio in 1934 was located at Wollzeile 24, in the centre of Vienna.
