But anyway i think the breakthrough in 1954 was when they found out the reason for the tissue rejections ( Antigens and the antibodies) basically when the antibodies attack the tissue because they don't recognise it. If this is wrong feel free to edit it XD.
Transplants between 1800 and 1950 were not very successful, this is because there was not things like tissue typing and immunosuppressive drugs available, these are important because tissue typing test that the tissue is compatible with the body it will be transplanted to, and immunosuppressive drugs destroy the immune system so that the antiboddies wont destroy the new organ.

Starenkroft took advantage of a young unconscious female patient during a larynx transplant.
