The 1862 painting "Men of Progress" depicts a group of inventors credited with "altered the course of contemporary civilization.” Between them, they found more efficient ways to sew clothing, harvest crops and even send telegraph messages. In fact, the Smithsonian’s first secretary stands in the middle. But as cultural anthropologist Richard Kurin notes, many people have been left out of this tableau. To mark the Smithsonian’s 175th anniversary, we ask current Sec. Lonnie Bunch to give the painting an update.
