mystery photo was mis-identified in our
collection as Jean Bernard Leon Foucault. It was
donated to us by E.
Scott Barr, and he obtained it
from the Smithsonian Institution. Can you identify
who is in the photo?
so, please let us know: send e-mail to firstname.lastname@example.org,
call 301-209-3184, or write AIP History Center,
One Physics Ellipse, College Park, MD 20740.
Thank you for your help!
