Herbert Weichmann (23 February 1896 – 9 October 1983) was a German lawyer and politician (Social Democratic Party SPD) and First Mayor of Hamburg (1965–1971). In his position as mayor of Hamburg, he served as President of the Bundesrat (1968–1969).
Weichmann was born in Landsberg, Upper Silesia, then part of the German Reich, to a Jewish family of physicians. In 1914 he began to study medicine, but volunteered at the outbreak of the First World War in 1914. After the war Weichmann studied law at the Silesian Friedrich Wilhelm University, Breslau, and graduated (Dr. iur.) in 1922. In 1928 he married Elsbeth Greisinger and was appointed as liaison officer to Prime Minister of Prussia Otto Braun. After the takeover of power (1933) by the Nazi Party Weichmann fled first to Czechoslovakia, then to France—with a short term of imprisonment (1939–1940)—Spain, Portugal and later the United States. In 1948 he returned to Germany at the invitation of the mayor of Hamburg, Max Brauer, and started his political career there. In 1956 he became a member of the faculty of the University of Hamburg. Weichmann died in Hamburg and is buried at Ohlsdorf Cemetery. Weichmann's son lives in Canada.
Weichmann started his political career on a soldiers' council (German: Soldatenrat) in 1918. In 1920, he became a member of the SPD. From 1948 until 1957, he was President of the Hamburg Court of Auditors. In 1957, he was appointed as Senator of Finance, a position he held until his election as First Mayor of Hamburg on 16 June 1965. Weichmann resigned in 1971. He was considered a potential candidate to be the next President of Germany, but he did not put himself forward.
In 1964 Weichmann was appointed as an honorary professor at the University of Hamburg. He was awarded Honorary Citizenship of Hamburg in 1971. In 1989 the non-profit organization Herbert und Elsbeth Weichmann-Stiftung was founded; its goal is to remember and commemorate the activities of the democratic opposition in exile against Hitler, and to promote academic works about political exile. In Uhlenhorst quarter a street was named Herbert-Weichmann-Straße. In 2007 the Herbert Weichmann medallion was granted for the first time by the city of Hamburg, honoring "those—both Jewish and non-Jewish—who have contributed to Jewish life in Germany".
