Mendel and the culture of commemoration

Last month (February 8th) was the 150th anniversary of Gregor Mendel reading the first part of his paper ‘Experiments on plant hybrids’ to the natural history society in Brünn, now Brno in the Czech Republic. Next Sunday (March 8th) will be the anniversary of Mendel reading the concluding part of his paper, an account of a long series of crossing experiments on garden peas.  The big commemorative celebrations will take place from 7th-10th September 2015 when international scientists gather at the Mendel Museum of Masaryk University in Brno for lectures and speeches on ‘Mendel’s legacy: 150 years of the genius of genetics’. In addition, the occasion will be marked by two linked exhibitions in the Mendel Museum: the already launched ‘Unseen for many years’ exhibition (8th February to 5th April) showcases Mendel’s original documents which have been brought home to Brno from the University of Illinois where they now belong. The second exhibition will feature the life of Mendel’s first biographer Hugo Iltis (1st October to 31st December). In between these there will be a display celebrating Mendel at the State Darwin Museum in Moscow titled ‘The Construction Set of Life’ (April 18th to May 31st). These events all affirm Mendel as the founding father of modern genetics.


This seems then to be a good moment to reflect on the ‘culture of commemoration’- how history of science is re-told and why ‘discovery narratives’ of the kind that surround Mendel are promoted. The lionisation of Mendel in England began soon after the ‘rediscovery’ of his paper around 1900 by three European botanists: de Vries in Holland, Correns in Germany, and Tschermak in Austria. Cambridge University zoologist William Bateson organized the first English translation of Mendel’s paper for the Royal Horticultural Society in 1901, and he arranged for the translation to be reprinted with modifications on several occasions. Bateson also published one of the earliest biographical notices of Mendel in a preface to his book Mendel’s Principles of Heredity: A defence (1909), from material he had collected on a pilgrimage to Brno in 1904. Bateson’s narrative included many aspects of the history we’re now familiar with – the theme of neglected genius, the sensational rediscovery and confirmation of Mendel’s experiments, and the idea that if Darwin had been able to read Mendel the development of evolutionary science would have been very different. Versions of this story (without any historically informed reflection on the relationship between Darwin and Mendel) appear in the biology textbooks we offer to today’s schoolchildren and students.

Images of Mendel’s garden were popular with early geneticists and were able to stand alone as icons of the Mendel discovery story. This one collected by William Bateson in 1910 was used by @JohnInnesCentre recently to commemorate Mendel’s paper.

For Bateson, commemoration was about bringing Mendel into general recognition. It was a calculated move in a battle he was engaged in with the English biometricians and other biological schools about the methods of biology and the causes of evolution. Bateson built his reputation and career with the authority of Mendel behind him. This relationship is nowhere better expressed than in the portrait of Bateson (below) taken at the Darwin Museum in Moscow in 1925. We know the saying ‘standing on the shoulders of giants’ but in this photograph, the bust of Mendel is tellingly perched above William Bateson’s shoulders, with rows of domestic chickens and guinea pigs, the stock-in-trade of contemporary genetics experiments, arranged attractively in display cases behind him. Little would we suspect from this image that at this point in his career Bateson had told his son Gregory (named after Mendel) that his life-long devotion to Mendelism had been a mistake, ‘a blind alley which would not throw any light on the differentiation of species, nor on evolution in general’ (Cock, 1980).

Commemoration is a collective endeavour that scientists engage in to build and sustain scientific disciplines (Haddad, 1999). Historians of science sometimes reinforce and at other times work against the discovery narratives that the act of commemoration produces. Revisionist accounts of the history of Mendelism have revealed how much of the complexity of early twentieth century biology gets forgotten in celebratory narratives. For example, we forget that Mendel’s three ‘re-discoverers’ had serious doubts about how widely Mendel’s laws applied; that within a year de Vries had turned away from Mendelian heredity; and that Tschermak’s interpretation of ‘Mendel’s principles’ differed significantly from Bateson’s. When re-reading Mendel’s paper we should also be mindful of Ronald Fisher’s (not dis-interested) conclusion that ‘Each generation, perhaps, found only in Mendel’s paper what it expected to find … [and] … ignored what did not confirm its own expectations’ (Fisher, 1936).

Mendel commemoration, of course, is not just for scientists or historians of science, it has had many other uses as well. Bateson attended the first international gathering to memorialise Mendel in Brno in 1910; he was present at the unveiling of the Mendel statue and gave one of the speeches. He witnessed the ceremonies being used to express German political power and commented that Mendel’s own Augustinian monastery and the Czechs were given a very minor role. The Abbot was the only one present at the celebrations who had known Mendel personally but he was not included in the speeches; the pre-celebration meeting and exhibition of Mendel documents took place in the ‘German House’ not the monastery, and the inscription on the monument was in German alone (Cock, 1982). Mendel’s story has also been used to promote science, or at least ‘free thinking’, over religion, notwithstanding his position as a friar and later Abbot within a monastic community. The photograph of Mendel in the Darwin Museum in Moscow records a time when it was possible for Mendel to represent the glories of science, within a state cultural modernisation programme that had its museum sculptors busy replacing religious icons with statues of scientists. When genetics later fell out of favour in Russia, Mendel’s clerical position made him doubly suspect.

To me the most surprising history of Mendel commemoration is the one recently unearthed by Ronald Numbers (Numbers, 2015). He documents that for almost a century Mendel and Bateson have been celebrated as creationist heroes. Mendel was embraced with enthusiasm by antievolutionists after Canadian-born school teacher George McCready Price began promoting Bateson’s statements against evolutionary theory to Christian fundamentalists. Though Bateson’s earlier books had said little about the relationship between Darwin and Mendel, his presidential address to the British Association for the Advancement of Science in Melbourne, Australia in 1914 began what became a long-standing creationist interest in Mendel. Price (bolstered with quotations from Bateson’s lecture) credited Mendelism with undermining Darwinism. If Mendelism allowed only for the varied re-assortment of hereditary characters already present there was no room for evolution. Later Bateson tried in vain to express his faith in evolution, to neutralise the coverage of his lectures that had provided fodder to the creationist camp. He failed, for Numbers shows that Mendel continues to be commemorated as a ‘creationist hero’ into the 21st century.

All of this shows that neither Mendel nor Bateson had control over the way their images or writings were represented. To borrow an insight from the Spanish author Javier Marίas, no one achieves silence, not even after death! It follows that studying the history of science is more than the interpretation of ‘landmark’ texts but must involve following ideas in circulation- studying both the people speaking on behalf of the dead scientists and the consumers of that information.


Postscript: A date for your diary

The John Innes Centre will have its own commemoration of Mendel when we launch our new annual history of science lecture (the Innes Lecture) within the Friends of John Innes Centre lecture series in April. We’re very pleased that the inaugural Innes Lecture will be given by Professor Greg Radick from University of Leeds. Greg, who teaches history and philosophy of science, has titled his lecture ‘Mendel the Fraud? A Social History of Truth in Genetics’.  This event will take place in the John Innes Conference Centre, on April 20th 2015 from 18.30 to 21.30.
