Passions : Criminal Victim : Concentration camp

Hugo Merton (18 November 1879 in Frankfurt am Main – 23 March 1940 in Edinburgh) was a German zoologist.
He studied sciences at the University of Heidelberg. From October 1907 to August 1908, with herpetologist Jean Roux, he conducted scientific investigations in the Aru and Kei Islands. In 1913 he obtained his habilitation at Heidelberg with a dissertation on the flatworm genus Temnocephala. Because of the 1935 Nuremberg Laws imposed by the Nazis, he was forced to relinquish his position as deputy director at the Senckenberg Museum in Frankfurt as well as his professorship at the University of Heidelberg.In 1937, by way of an invitation from Professor F. A. E. Crew, he went to the University of Edinburgh, where he spent time working in the institute of animal genetics. Upon this return to Germany in 1938, he was arrested and imprisoned in the concentration camp at Dachau. During the following year, he was deported to Scotland, where he resumed his work at the university. Due to deteriorated health, he died soon afterwards in March 1940.Organisms with the specific epithet of mertoni are named in his honor, an example being the sea snake species Parahydrophis mertoni. In 1911, Max Carl Wilhelm Weber named the fish species Pseudomugil gertrudae after Merton's wife, Gertrude.

Ottilie Metzger-Lattermann also formerly Ottilie Metzger-Froitzheim (15 July 1878 – February 1943) was a German contralto who was a famous performer of works by Wagner during the 1910s, and who after her retirement was murdered in Auschwitz.

Theodor Haubach (15 September 1896 in Frankfurt am Main – 23 January 1945 in Berlin) was a German journalist, SPD politician, and resistance fighter against the Nazi régime.
Theodor Haubach spent his childhood and youth in Darmstadt. In 1914, right after his Abitur, he took part in the First World War as a volunteer, and was wounded repeatedly. After the horror of his wartime experiences, Haubach resumed studying.
From 1919 to 1923, he studied philosophy, sociology, and economics and eventually graduated. As of 1920, Haubach, like his friend Carlo Mierendorff, was an SPD member and worked together actively with the Young Socialists. From 1924 to 1929 he was editor of the newspaper Hamburger Echo, and later (1929-1933) an associate at the Reich Interior Ministry and with the Berlin Police President. From 1924 Haubach was the leading member of the Reichsbanner Schwarz-Rot-Gold, an association that campaigned fiercely for the Weimar democracy and actively struggled under the emblem of the "Three Arrows" against the Nazis, who were grasping for power.
Beginning in February 1933, Haubach, like many SPD members, was persecuted by the Nazi régime. After his first arrest in 1934, he was detained in Esterwegen concentration camp. From 1935, he worked as an insurance representative, and later established contacts with the Kreisau Circle. After the failed attempt on Hitler's life at the Wolf's Lair in East Prussia on 20 July 1944, Haubach was arrested and sentenced to death by the Nazi "People's Court" (Volksgerichtshof). Now very ill, Theodor Haubach was hanged on 23 January 1945 along with Helmuth James Graf von Moltke at Plötzensee Prison in Berlin.

Interned in the late 1930s in the concentration camps at Dachau and then Buchenwald, he was released through the efforts of his future wife Dora, and emigrated to the United States. There he continued to publish books and contribute to newspapers before returning to Europe after the Second World War. Ill health, aggravated by his experiences in the camps, dogged him in later life, but he continued to publish through to the end of the 1950s. He wrote also under the pen names Henry E. Jacob and Eric Jens Petersen.
