“A Close Brush With History, The Curious Collection of Peter A. Browne, an illustrated lecture by Robert McCracken Peck”

Monday, 5/11/26, at 7:30 PM
Doors open at 7 PM
11 Veterans Sq., Media, PA 19063
This lecture will also be live-streamed on the DCIS Facebook Channel!

What will the lecture cover, I hear you ask?

Peter Arrell Browne, a nineteenth-century naturalist and early member of the Delaware County Institute of Science, gained international renown for his collection of human hair. Thirty years before Charles Darwin revolutionized our understanding of the descent of man, Browne tied to trace human origins by collecting hair from around the world. His remarkable collection, the largest of its kind ever made, includes scores of celebrities from Napoleon Bonaparte and George Washington to Thomas Jefferson and a dozen other U. S. presidents. It is the subject of Peck’s book, Specimens of Hair, The Curious Collection of Peter A. Browne. Don’t miss this delightful presentation about Browne’s significant brush with history!
