↑ Witkowsky explanation is actually based on the account of a visiting medical researcher, Ralph Buchbaum, who reports being told by a technician in Carrel's lab "Dr. Carrel would be so upset if we lost the strain, we just add a few embryo cells now and then". After the first six months, Carrel's colleague Albert Ebeling had actually taken charge of the cultures and published several papers about their development, until they were eventually discarded in 1946. Witkowsky, in "Dr. Carrel's immortal cells", op. cit., quotes Buchbaum's account. At the end Buchbaum writes that "I told this story, of my visit to Carrel's laboratory, to various people. Dr. Bloom (Buchbaum's director of research in Chicago)refused to believe it. Others chuckled gleefully. Dr. Carrel was to blame only in that he did not keep on top of what was really going on in the laboratory (mostly, he wrote the papers). Dr. Parker and Dr. Ebeling probably suspected something, hence the "retirement". In the interest of truth and science, the incident should have been thoroughly investigated. If it had been, some heads might have rolled, sacrificed to devotion to a wrong hypothesis - immortality of cell strains.". Witkowsky also reports a Dr. Margaret Murray telling him that "one of Carrel's technicians of that time was passionately anti-fascist and detested Carrel's political and social ideas" and expressing her belief that "that this technician would willingly have discredited Carrel scientifically if possible.".
