Fregattenkapitän Heinrich Lehmann-Willenbrock (11 December 1911 – 18 April 1986) was a submarine commander in the Kriegsmarine of Nazi Germany during World War II.

The story of the U-96 was eventually made into a mini-series and film called Das Boot, in which the captain was portrayed by Jürgen Prochnow.

[1] In April 1935, Lehmann-Willenbrock was commissioned as a Leutnant zur See (Lieutenant) and assigned as signals officer onboard the cruiser Karlsruhe.

The following year, in September 1936, he was assigned for five months to the Naval Barracks at Glücksburg before receiving orders to report as Watch officer onboard the sailing vessel Horst Wessel.

The seventh patrol was the approximate time that Lothar-Günther Buchheim boarded U-96 and documented the boat's operations in his book Das Boot.
