Biographical / Historical

Mogens Frederick Hallgren was born on December 9, 1920 to Carl and Frida Hallgren on Bornholm, a Danish island in the Baltic Sea. His family immigrated to the United States when he was a toddler and he grew up in Cliffside Park, New Jersey. Following graduation from high school, Hallgren worked with his father at Boyen Lighterage and became the youngest barge captain in New York Harbor.

When World War II broke out, he was not able to join the Navy as he wished as he was not yet an American citizen. Instead, he asked to join the 10th Mountain Division at Camp Hale, Colorado. After training at Camp Hale and Camp Swift, Texas, he deployed with the 10th Mountain Division to Italy, where he was awarded a Bronze Star Medal. Hallgren attained the rank of Technician 5th Grade in the 85th Infantry Regiment, Company C.

Following the war, Hallgren worked as a city policeman, a New Jersey state trooper, a real estate investor, and he also owned a small store in Hanover, New Hampshire. In 1987, Hallgren met and married Joeanne Schoolfield. Hallgren died on January 21, 2016 in Fort Worth, Texas.
