Michael Vann (California State University, Sacramento) returns to the Infectious Historians (our first returning guest!), this time to focus on the biography of Alexandre Yersin, the Swiss-French doctor who discovered the bacterium that causes plague. The discussion covers Yersin’s biography from childhood, through his move to southeast Asia, his successful career and larger-than-life reputation - alongside the less palatable aspects of Yersin’s life. The conversation also touches upon issues such as Yersin’s entrepreneurship, his life as a European within a colonial context, and his personality.
