The chart below tracks the relative priority of the topic of eugenics in the American high school biology curriculum. It is based on review of 80 textbooks published between 1907 and 1969. Though there are exceptions, as a rule, textbooks first published in the years prior to 1938 were generally more eugenic than average in their later editions, and textbooks published from 1938 on were generally less eugenic than average in their later editions. Further, with the exception of Moon (first published in 1921), only the less eugenic Smith and Kroeber and Wolff texts survived into the 1960s.

A couple of additional observations:

Scopes: As the chart indicates, the Scopes-era anti-evolution movement in the United States correlated with the peak of eugenic fervor in American biology textbooks. However, the movement was indiscriminate. Any textbook that contained an explicit mention of human evolution, whether that particular text promoted eugenics or not, was subject to censorship – from the most harshly eugenic, like William Atwood’s 1922 Civic and Economic Biology, to the sweet, like Gilbert Trafton’s wonderful 1923 Biology of Home and Community. The latter, though it featured no eugenic language, generated controversy in North Carolina. Despite after the fact claims from creationists, eugenics does not seem to have concerned early fundamentalists.

The Rise of Nazism and World War II: Though Raymond Pearl criticized eugenics as far back as 1927, and the Nazi application of harsh negative eugenic measures pushed liberal scientists like Julian Huxley and Hermann Muller to frame a softer reform eugenics in the mid-1930s, the data demonstrate no sharp drop in the presentation of the topic through the 30s, 40s and 50s, only a gradual decline. This supports Wendy Kline’s claim from Building a Better Race (2001) that the eugenics movement was not “weak and discredited after 1930,” as many scholars contend, but had worked its way deeply into the popular consciousness.

Evolution vs. Eugenics: Though the topics of evolution and eugenics were tightly wed in the economic and civic biologies published from 1914 through the latter 1920s, textbooks with the strongest and most up to date presentation of evolution (Smith, Kroeber and Wolff) were significantly less eugenic than popular textbooks with poorer evolutionary content (Smallwood, Curtis and particularly Moon).

Moon: As with the data tracking the relative priority of the topic of evolution (see chart), the popular Moon text skews the results (see related article). Combined, the data suggest that though conservative regions of the country may have taken issue with the teaching of the topic of evolution, the teaching of eugenics, which discouraged mating across race and class lines, was less controversial.

  2. Mark, I enjoyed your dissertation and have now moved Breeding Contempt to the top of my must read list. Can’t wait. Wow, 200 biology textbooks? That’s impressive. You haven’t got a list of titles you might share by any chance? Though my high school collection (1907-mid-60s) is pretty comprehensive, my college collection is spotty. I’d love to begin filling it in.

  3. I am writing a paper on the history of genetics education and specifically looking for the first mention of the term “genetics in Biology textbooks. I am starting with books written in the 1900’s. If you could contact me I would appreciate it very much. Thank you. Caren Gough

  4. Thanks Mark, I’d tracked your book down a few months ago. Your list dovetails quite nicely with mine, as it seems to fairly thoroughly cover textbooks published from the 1960s on, whereas mine is comprehensive (for American high school texts) only up to the mid-1960s or so. I would be interested to see your p. 129 chart supplemented by data from the critical period between 1905-1929. My guess is your lower “supportive” line, like the analysis above, would closely trace the ‘eugenics’ nGram.
