This book offers a tour of the history of medical virology in the Netherlands from the nineteenth century to the new millennium. Beginning with the discovery of the first virus by Martinus Beijerinck in 1898, the authors investigate the reception and redefinition of his concept in medical circles and its implications for medical practice, particularly in the diagnosis and prevention of viral infections. The relatively slow progress of these areas in the first half of the twentieth century and their explosive growth in the wake of molecular techniques are examined. The surveillance and control of virus diseases in the field of public health is treated in depth, as are tumour virus research and the important Dutch contributions to technical developments instrumental in advancing virology worldwide. Particular attention is paid to oft forgotten virus research in the former Dutch colonies in the East and West Indies and Africa.

In 1965, French microbiologist André Lwoff was awarded the Nobel Prize in Physiology or Medicine for his work on lysogeny—one of the two types of viral life cycles—which resolved a contentious debate among scientists about the nature of viruses. A Tale of Two Viruses is the first study of medical virology to compare the history of two groups of medically important viruses—bacteriophages, which infect bacteria, and sarcoma agents, which cause cancer—and the importance of Lwoff’s discovery to our modern understanding of what a virus is. Although these two groups of viruses may at first glance appear to have little in common, they share uniquely parallel histories. The lysogenic cycle, unlike the lytic, enables viruses to replicate in the host cell without destroying it and to remain dormant in a cell’s genetic material indefinitely, or until induced by UV radiation. But until Lwoff’s discovery of the mechanism of lysogeny, microbiologist Félix d’Herelle and pathologist Peyton Rous, who themselves first discovered and argued for the viral identity of bacteriophages and certain types of cancer, respectively, faced opposition from contemporary researchers who would not accept their findings. By following the research trajectories of the two virus groups, Sankaran takes a novel approach to the history of the development of the field of medical virology, considering both the flux in scientific concepts over time and the broader scientific landscapes or styles that shaped those ideas and practices.
