Yes, Heinrich Himmler was the leader (or Reichsführer)the SS (Schutzstaffel) from January 6, 1929 until April 29, 1945.

Some were put on trial; some of these were convicted and a few were hanged. A few of the most wanted SS men (like Franz Stangl, Commandant of Treblinka) escaped to Latin America, especially Argentina, Paraguay and Brazil. Most, however, went home, got jobs and went on to enjoy the benefits of the West German ecnomic miracle of the 1950s and 1960s.

I'm assuming you mean Reichsführer-SS Heinrich Himmler, the most (in)famous person of that name. His wife was Mrs. Himmler (whose maiden name was Margarete Boden). He also had a mistress (Hedwig Potthast).

For an Waffen-SS soldier any Soldier could remove Jews from their homes and put them on trains to the concentration camps but the orders must come from at least a SS- Sturmbannführer: SS-Storm Command leader

or a anyone who has a high power of authority

For the German Soldiers, Only soldiers with the rank of Obergefreiter could do the job of evacuating Jews from their homes but only can be done from a military personal with the rank of Major
