As historian of science Lorraine Daston recently remarked, COVID-19 has thrown us back into a state of “ground-zero empiricism.” The manifold manifestations of COVID-19 and the many unknowns involved are provoking scientific speculation that is often based on nothing more than chance observations and personal anecdotes. The radical uncertainty of the current situation, writes Daston, has catapulted us back to the seventeenth century, with almost everything up for grabs, “just as it was for the members of the earliest scientific societies—and everyone else—circa 1660.”1
We are all historians of the present. At least we should be. Many fellow historians of knowledge are currently using a wide variety of media to share their experience and research in an effort to put the global response to the COVID-19 pandemic into context. Twitter is one medium where this conversation is especially lively, as Eileen Sperry has noted on Nursing Clio, a wonderful group blog that is also active on Twitter. One can find these parts of Twitter by searching for the relevant hashtags, for example, #histmed (history of medicine) and the much more generic #twitterstorians (historians on twitter).
