Gemeinnützige Krankentransport GmbH
The Gemeinnützige Krankentransport GmbH (German: [ɡəˈmaɪnˌnʏtsɪɡə ˈkʁankŋ̍ˌtʁanspɔʁt ɡeːʔɛmbeːˈhaː] ; known as "Gekrat" or "GeKraT", commonly translated as "Charitable Ambulance") was a subdivision of the ⓘAction T4 organization. The euphemistically named company transported sick and disabled people to the Nazi killing centers to be murdered under the Nazi eugenics program and was known for the gray buses it used. The many victims were murdered in sealed gas chambers with carbon monoxide gas supplied in metal gas cylinders, and fed through false spray heads appearing to be shower heads. The programme Aktion T4 was managed by Viktor Brack, who was tried for his crimes at Nuremberg, and executed as a result. The operation was ordered by Adolf Hitler in early September 1939, and organized by Philip Bouhler and Karl Brandt of the Reich Chancellery.
