Mildred Fish-Harnack Day is Sept. 16 in Wisconsin. It is also one of the Wisconsin Public School Observance Days.

This day, the same as her birth date, commemorates the life of Mildred Fish-Harnack, a Milwaukee native who chose to serve as a spy for the Allied forces and fight the Nazi regime in Germany. She became the only American civilian known to have been executed by direct order from Adolf Hitler. Fish-Harnack gave her life to save the lives of others and the Germany she loved.
