While tension between religious commitment and evolution has often been perceived as a Christian American phenomenon, the current article joins a growing body of literature that illustrates how some Jewish Americans have also struggled with Darwinism. This article will focus in on the case of the Association of Orthodox Jewish Scientists (AOJS), and document its members’ engagement with evolution in the 1960s and 70s. Although founded in New York in 1948, the AOJS did not grapple with the issue of evolution in its first decade. When evolution did come to the fore in the 1960s, a time when the Christian American discussion of evolution also escalated, AOJS members expressed a spectrum of views on the matter. Those who strongly critiqued evolution, however, were more prolific in their writing on the subject than those who expressed positive attitudes towards evolution. This article highlights historical and sociological factors within American and Jewish life in the second half of the 20th century that are related to this outburst of antievolutionism on the part of some AOJS members in this period. It further illustrates that the negative view of evolution promoted by some members was not suppressed or censured by the association, despite the fact that it may well have been a minority view within the group. Lastly the article suggests that the American Orthodox scientists adopted the model of agreeing to disagree on the matter of evolution because they placed the value of Orthodox Jewish unity above other scientific and social considerations and goals.
