Chief hair

The Academy of Natural Sciences in Philadelphia is marking Presidents Day with an exhibit of presidential hair later this month.

The "hair album" was assembled by Peter Arvell Browne, a Philadelphia attorney and scholar of the natural sciences in the 1800s.

He collected samples of the first 12 presidents' hair.

Because the scrapbook is so fragile, it will be opened only to the page featuring George Washington's brown-and-gray locks.

Photographs will be shown of the other presidents' hair, from John Adams to Zachary Taylor.

Curator Robert Peck says the hair samples give a sense of the what the earliest presidents were like as people.
