Above and Below the Surface: Maritime History of the Great Lakes

The Beaumier U.P. Heritage Center is proud to announce the 25th annual Sonderegger Symposium will take place on Friday, November 14. The title of Sonderegger25 is Above and Below the Surface: Maritime History of the Great Lakes and will be held in Northern Center Ballroom IV on the campus of Northern Michigan University. Admission is free and open to the public. This event is funded by a donation from the Sondregger family in honor of Dr. Richard Sonderegger, former head of the History Department at NMU.  

This year’s Sonderegger Symposium is inspired by the 50th anniversary of the sinking of the Edmund Fitzgerald on Lake Superior but will deal with far more than just that tragic event. The speakers are noted maritime scholars, authors, curators and divers who will present a breadth of knowledge at this year’s event. There will even be a performance of maritime music to conclude the day’s activities. Below is the line-up of speakers with times and topics. For more information on the speakers, go to this link.
