What began as a brain trust of the art world’s finest during the war became a group of 345 men and women from 13 countries that comprised the Monuments, Fine Arts and Archives Section unit. They spent 1945 seeking out more than 1,000 troves containing an estimated 5 million pieces of artwork and cultural items stolen from wealthy Jews, museums, universities, and religious institutions. And for six years after the surrender, a smaller group of about 60 Monuments Men continued scouring Europe as art detectives.
