Carl von Marr Day 

Carl von Marr Day

Each year we celebrate the museum's founding legacy and honor Carl von Marr near his February 14 birthday. This year's Carl von Marr Day welcomed Dr. Caitlin Pepperell, a professor at the University of Wisconsin–Madison and an infectious diseases physician and biologist who studies disease ecology and pathogen evolution. Her expertise in the science of epidemics took center stage for an in-depth talk on the evolution of Yersinia pestis, the agent of the Black Death. Cake followed the talk to honor Marr's birthday.
