Forget about public meetings (none, I think) or school (it’s break!) — the Wisconsin Historical Society has the one fact worth noting, today:
On this date [in 1874] magician Harry Houdini was born in Budapest, though he later claimed to have been born on April 6, 1874, in Appleton, Wisconsin. At the age of 13 he left Appleton, where his family had emigrated, for New York City, and began his career as an escape artist and magician. [Source: Outagamie County Historical Society]
