David Siegel has been with the Green Bay (Wisconsin) Metro Fire Department since 1997. He is a lieutenant at Station 5 on East Mason Street, a paramedic and the science officer for the hazardous materials team. Previously, he worked as a biochemist after earning BS and MS degrees in that field from the University of Wisconsin-Madison. In 2012, he earned a BS in Fire Science and Engineering Technology from the University of Cincinnati. Researching and writing the book Forces of Change, Events That Led To The Development Of The Green Bay Fire Department, 1841-1895 (released 2016) combined a passion for that fire department, a life-long love of history and an inner-drive to know more.
