Leopold Bloch was born in Freiburg on 26 January 1876. As a young man, he trained at the Electrotechnical Institute in Karlsruhe, which was founded in the 1890s.
After becoming a doctoral engineer, Leopold Bloch moved to Berlin.
At first he lived in the Wilmersdorf district, at Brandenburgische Straße 36, directly on Adenauer Platz. He then moved to what was then Cecilienallee, now Pacelliallee 57, in Berlin Dahlem. There he lived with Bertha Wallach and her husband Ludwig, Siegfried Ksinski and Thekla Schönbeck until his deportation.
Because of his Jewish descent, he was persecuted by the National Socialists. On 18 October 1941, Leopold Bloch was deported to Lodz in Poland with 1081 other victims of the National Socialist regime.
Unfortunately, we do not know very much about Leopold Bloch, for example about his family. However, we assume that Leopold had a sister named Laura Bloch, who was born on 26 October 1875, i.e. a little more than a year before Leopold, also in Freiburg, and was deported from Stuttgart to Theresienstadt on 22 August 1942.
On 17 December 1941, Leopold Bloch was murdered at the age of 65 along with many other innocent people.
