Hans Heinrich Lammers (27 May 1879 – 4 January 1962) was a German jurist and prominent Nazi politician. From 1933 until 1945 he served as Chief of the Reich Chancellery under Adolf Hitler. During the 1948–1949 Ministries Trial, Lammers was found guilty of war crimes and crimes against humanity and sentenced to 20 years' imprisonment. Early life Born in Lublinitz (now Lubliniec, Poland) in Upper Silesia, the son of a veterinarian, Lammers completed law school at the universities of Breslau (Wrocław) and Heidelberg, obtained his doctorate in 1904, and was appointed judge at the Amtsgericht (district court) of Beuthen (Bytom) in 1912. During World War I, as a volunteer and officer of the German Army, he received the Iron Cross, First and Second Class. After World War I he joined the national conservative German National People's Party (DNVP) and resumed his career as a lawyer reaching by 1922 the position of undersecretary at the Reich Ministry of the Interior.

At the recommendation of Interior Reichsminister Wilhelm Frick, he became the centre of communications and chief legal adviser for all government departments. In October 1933, he was made a member of Hans Frank's Academy for German Law. From 1 December 1937, he was a member of Hitler's cabinet as a Reichsminister without Portfolio. On 30 August 1939, immediately prior to the outbreak of the Second World War, Lammers was appointed by Hitler to the six-person Council of Ministers for Defense of the Reich, which was set up to operate as a "war cabinet". In that position, he was able to review all pertinent documents regarding national security and domestic policy even before they were forwarded to Hitler in person. The historian Martin Kitchen explains that the centralization of power accorded to the Reich Chancellery and therefore to its head made Lammers become "one of the most important men in Nazi Germany". From the vantage point of most government officers, Lammers seemed to speak on behalf of Hitler, the ultimate authority within the Reich. Lammers was also one of the first officials to sign government correspondence with "Heil Hitler", which became a requisite greeting for civil servants and eventually so ubiquitous that failure to
