Baruch S. Blumberg was a physician and geneticist most well known for identifying the Hepatitis B virus and for creating a vaccine. The American Philosophical Society (APS) recently created this online exhibit about Blumberg that was "designed to highlight the influence of the philosophy of science that coursed through his scientific career." This exhibit features a number of primary documents that may be of interest to students of science and philosophy alike. For example, visitors can explore a handwritten diagram that Blumberg created to represent the scientific research process. As the exhibit notes, this document was informed by the ideas of Karl Popper and Jacob Bronowski. Visitors can also read a 1980 letter that Blumberg wrote to philosopher Thomas Kuhn. All items in this exhibit come from the APS's Baruch S. Blumberg papers; researchers interested in learning more about what is in this collection can find complete collection information via the link at the bottom of this exhibit.
