T-4 was the code name for the Nazis euthanasia programme of the disabled. This programme was named T-4 after the address of its headquarters Tiergartenstrasse 4. Although the programme was carried out in secrecy, it became hard to conceal and soon became public knowledge. There was considerable public and private outrage over the murders. Under pressure from public, Hitler publically ordered a halt to the programme on the 24 August 1941. The gassing centres were dismantled and shipped to the new camps in the occupied east. Despite Hitler’s public order, the programme was in fact still encouraged to continue in a decentralised form.
