Carl Hau
German criminal, jurist and actor (1881-1926)

Carl Hau (or Karl Hau; 3 February 1881 – 5 February 1926) was a German lawyer found guilty of murdering his mother-in-law. His sensational trial in 1907 sparked the Hau Riot, the biggest street riot of its kind in German history.
Life
Hau was born on 3 February 1881 in Grosslittgen near Wittlich in south-west Germany close to the Luxembourg border. His father Johan Baptist Hau was a bank director. Carl's mother died when he was three. He was educated in Trier.
He was studying Law at the University of Freiburg when in 1901 he contracted tuberculosis which was widespread in Europe at that time. He went to the Mediterranean island of Corsica to recover in the Spring of 1901, taking rooms in the pretty town of Ajaccio on the island's west coast. During this stay he met a widow, Josephina Molitor (née Stadelhofer), a mother of seven children, who was there with her two youngest daughters, Lina (25) and Olga (19). The group started going for walks together and both daughters liked Hau, who was very polite.

Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
