History Revealed: Ordnance Plant

November 21, 2019 @ 7:00 pm - 8:30 pm

Ramsey County Historical Society Presents

Mark Haidet, The Twin Cities Ordnance Plant During World War II

History Revealed Series
November 21, 2019
Thursday, 7:00 pm
Ramsey County Roseville Library

Free and open to all. No reservations needed.

Join RCHS for History Revealed, our program series featuring presentations and tours from the best of local historians, authors and archaeologists, with a wide range of topics drawn from the heritage and traditions of Ramsey County.

Historian Mark Haidet will tell the story behind the building of The Twin Cities Ordnance Plant and its key role in helping the United States and its Allies win World War II.  The rapid transformation of northwestern Ramsey County from farm fields in 1941 into an industrial complex employing more than 25,000 men and women at its peak in 1943 was called a miracle.

Mark Haidet worked for the Minnesota Historical Society for 36 years – 10 years as a historian and 26 years in the Development Office.  As Director of Development for the program’s first 16 years, he built a comprehensive program and led three major campaigns for the Minnesota History Center, Mill City Museum and the Greatest Generation Project.  He closed his career with three years at the State Fair Foundation where he completed the campaign to build the Fair’s new History & Heritage Center.  Now retired, Mark is helping others as a free-lance historian and fund-raising consultant.
