Euthanasia societies[which?] were formed in England in 1935 and in the USA in 1938 to promote euthanasia. Although euthanasia legislation did not pass in the USA or England, in 1937, doctor-assisted euthanasia was declared legal in Switzerland as long as the doctor ending the life had nothing to gain.[11][19] During this same era, US courts tackled cases involving critically ill people who requested physician assistance in dying as well as “mercy killings”, such as by parents of their severely disabled children. | Euthanasia societies[which?] were formed in England in 1935 and in the USA in 1938 to promote euthanasia.
