A tooth at Piltdown
In December 1912 Dawson and Woodward announced Eoanthropus dawsoni, “Dawson’s dawn man”: a thick, human-looking braincase and an ape-like jaw from a gravel pit at Barkham Manor, Piltdown. Teilhard dug there with them. His biographer Mary Lukas counts three visits in Dawson’s lifetime: 21 May 1912, the weekend of 8–10 August 1913, and 30 August 1913, when, stopping on his way back to France, he spotted in the spoil the worn canine tooth that Woodward had predicted the jaw should carry. It seemed to tie jaw and skull together. In 1915 Dawson reported a second set of remains from a second site, which he never precisely located; Lukas places it in a field at Sheffield Park, about two miles away. The second find made the “man” look like a population rather than an accident. Teilhard himself wrote in 1920 on “the case of Piltdown man”, a paper the 2016 investigators list among early suggestions that an ape fossil had been mixed in with a human skull.
In 1953 Kenneth Oakley, J. S. Weiner and W. E. Le Gros Clark proved the whole thing a forgery: a human skull, an orang-utan jaw with filed teeth, everything stained to match the gravel. In 2016 a team led by Isabelle De Groote, with Natural History Museum scientists including Chris Stringer, ran DNA, CT and spectroscopic tests on the specimens. They found a single orang-utan and at least two humans, and the same method throughout, brown stain, packed gravel fragments and filling material, at both sites; they attribute the work to one forger, Dawson, the only person known to be directly associated with the finds at the second site. “Whether Dawson acted alone is uncertain,” they add, and they list Teilhard, the finder of the canine, among the long-standing suspects.
The accusation came from Stephen Jay Gould, who floated a version in his Natural History column of March 1979 (“I can easily imagine Dawson and Teilhard, over long hours in field and pub, hatching a plot”) and argued it in earnest in August 1980. He reprinted that essay, as “The Piltdown Conspiracy”, in Hen’s Teeth and Horse’s Toes (1983), correcting factual slips only in footnotes. He did not make Teilhard the mastermind: “J. S. Weiner’s elegant case virtually precludes Dawson’s innocence,” he wrote, and Dawson had made the first finds before Teilhard arrived. He ranked his arguments by strength and rested the case on two. The first was a letter. On 28 November 1953 Teilhard, answering Oakley, wrote that Dawson “just brought me to the site of Locality 2 and explained me [sic] that he had found the isolated molar and the small pieces of skull in the heaps of rubble and pebbles raked at the surface of the field.” Dawson announced those finds in 1915, and Teilhard had been mustered into the French army in December 1914. “He could not have seen the remains of Piltdown 2 with Dawson,” Gould wrote, “unless they had manufactured them together before he left.” Pressed by Oakley in January 1954, Teilhard answered that his “souvenirs” were “a little vague”, and in March he told Mabel Kenward of Barkham Manor that Dawson had shown him the field but “I cannot remember whether it was after or before the find.” Gould read this, together with smaller misstatements (Teilhard dated his first meeting with Dawson to 1911, not 1909, and described himself at Hastings as “not allowed to leave much his cell”), as “a subtle attempt to direct suspicion away from himself.”
His second argument was silence. After one short article in 1920, “Le cas de l’homme de Piltdown”, in which Teilhard sided with anatomy against geology (“We must suppose that the Piltdown skull and jaw belong to two different subjects”), Gould found “fewer than half a dozen references” to Piltdown in the twenty-three volumes of his collected works, nearly all a footnote or a dot on a family tree. Yet the skull, which looked more modern than Neanderthal man and was older, was the best fossil support for the parallel lineages that Teilhard’s evolutionary philosophy needed. In the 1920 article Teilhard remarked that the jaw’s missing hinge made it impossible to test whether jaw and skull fitted: “As if on purpose [comme par exprès], the condyle is missing!” Gould read those words at two in the morning and could not shake them: “I think that Teilhard was trying to tell us something he didn’t dare reveal directly.” He added Oakley’s recollection that Teilhard changed the subject whenever Piltdown came up, and walked “glumly” through a British Museum display of the exposure “as fast as he could, eyes averted”. On motive he guessed at a prank that “went too far”: “a delicious joke for him — at first”, which became impossible to confess once the war had taken Teilhard away, Dawson had died in 1916 and a scientific career had opened for him. Gould graded his own evidence. The North African animal teeth in the gravel (a Maltese hippo, a Tunisian elephant; Teilhard had taught in Cairo from 1905 to 1908) were “suggestive, but not compelling”, and Teilhard’s luck in finding the canine was “the weakest point of all”. He called the whole case circumstantial, “as is the case against Dawson or anyone else”, and wrote: “I believe that the burden of proof must now rest with those who would hold Father Teilhard blameless.”
The replies came within weeks. The press carried the charge from the New York Times to Time, which quoted Teilhard’s friend George Gaylord Simpson: “I don’t think it was in his character.” In Natural History in June 1981 the anthropologist S. L. Washburn, who had known Teilhard, wrote that Gould “cites no direct evidence against Teilhard” and that “to be shown a fake does not make a person a faker”: Dawson, who wanted fame, had every reason to enlist a friendly young priest to make some of the finds, Teilhard “had nothing to gain by being a secret conspirator” and risked everything, and a Jesuit wary of acrimonious controversy might simply have kept out of the Piltdown quarrel. Gould answered that Washburn and Edward Dodson spent most of their space on his subsidiary points. Mary Lukas, Teilhard’s biographer, argued in America (May 1981) and in the Teilhard Newsletter that Teilhard really had stood in the Sheffield Park field in 1913: Dawson drove him past it, and on 3 July 1913 Dawson wrote to Woodward of a skull fragment from a new plough field far from Piltdown. Teilhard, she suggested, later fused what Dawson said that summer with the 1915 announcement; “he had only seen the site; he had heard from Dawson about the fossils.” Gould replied that he had never doubted the visit, only the claim of foreknowledge. He went to the British Museum in February 1982 prepared, he wrote, to give up that part of his case, and read the letter: “I have picked up the frontal part of a human skull this evening on a plough field covered with flint gravel. It is a new place, a long way from Piltdown.” That fragment, he argued, was a thin frontal bone, not part of the Piltdown 2 material, so “the smoking gun turned out to be a red herring”. He granted that a muddled memory forty years on could still exonerate Teilhard, but called it “special pleading”, and he had earlier rated it the only alternative to complicity he found “at all plausible”. On Peter Costello’s Antiquity article, which published Teilhard’s warm farewell letter to Dawson of 10 July 1912, Gould said conspirators can be loyal and grateful too.
Nobody settled it. Oakley told the Times in July 1980 that Teilhard’s letters gave him “strong indications” of collusion; Weiner replied that there was “no positive unequivocal evidence of Teilhard’s connivance”. Gould reports that Oakley later urged, in print, that Teilhard be given the benefit of the doubt, and that a friend told him he had established “the grounds for an indictment, but not for a conviction”. In 1983 Gould wrote that no good arguments had been raised against him, but that “nothing of great consequence has turned up in my favor either”; he had half hoped for a confession in a bank vault. In 2016 Francis Thackeray suggested Teilhard may have been in on a joke played against Dawson by someone who knew Dawson was a fraud. What is evidenced is narrow. Teilhard found the canine; the 2016 tests point to Dawson’s method, and say nothing about who else knew; no specimen or contemporary document ties Teilhard to making any of the fakes; and the case against him is an inference from a pattern of late letters and a silence that the two sides read in opposite ways.
