Popular science writing has received increasing interest, especially in its relation to professional science. I extend the current scholarly focus from the nineteenth to the twentieth century by providing a microhistory of the early popular writings of evolutionary biologist John Maynard Smith. Linking them to the state of evolutionary biology as a professional science as well as Maynard Smith’s own professional standing, I examine the interplay between author, text and audiences. In particular, I focus on Maynard Smith’s book The Theory (...) of Evolution and show how he used it to both promote neo-Darwinism and advocate the utility of mathematics in biology. Following in the footsteps of Charles Darwin and David Lack, Maynard Smith was a science communicator blurring the lines between genres and audiences while contributing to ongoing discussions within and on the profession of evolutionary biology around the Darwin-Wallace centenary.

John Maynard Smith was one of Britain's most eminent evolutionary biologists. For over forty years, from 1954 onwards, he also regularly appeared on radio and television. He primarily acted as a scientific expert on biology, but in the late 1960s and the 1970s he often spoke on the implications of science for society. Through four case studies, this paper analyses Maynard Smith's scientific broadcasting against developments within the BBC as well as the relation between science and society in Britain. It (...) finds that while Maynard Smith acknowledged and accepted increasing mediation through the BBC and its producers, he stayed publicly and privately critical of both format and content decisions in his reflections on the science–media relationship. At the same time, we find that over a decade before the 1985 report by the Royal Society on the public understanding of science, Maynard Smith came to think of engagement with the public via the media as scientists’ responsibility.
