Ernst Kaltenbrunner
Heydrich's replacements were Ernst Kaltenbrunner as the chief of RSHA, and Karl Hermann Frank (27–28 May 1942) and Kurt Daluege (28 May 1942 – 14 October 1943) as the new acting Reichsprotektors. After Heydrich's death, implementation of the policies formalised at the Wannsee conference he chaired was accelerated. The first three true death camps, designed for mass killing with no legal process or pretext, were built and operated at Treblinka, Sobibór, and Bełżec. The project was named Operation Reinhard after Heydrich.
