» History

Plant Pathology at UW–Madison has a rich history dating back to its founding in 1910. Much of this history is detailed on the ‘History’ page of our website. However, I’m happy to report that six new ‘History Note’ publications have been published on our web page this year, each providing a deeper dive into a topic of particular, and perhaps overlooked, historical importance to the department. Special thanks to Emeritus Professor Douglas Maxwell for leading the efforts in creating these fascinating documents.

I encourage you to visit the departmental History webpage and scroll down to view the History Note Fact Sheets and learn even more about the contributions our department has made to the advancement of Plant Pathology!
