Albert Einstein, Paul Langevin, and unidentified others

This photo was taken in Paris, France, and most likely at the home of Paul Langevin, who had invited Einstein to Paris. Those seated are (l. to r.): Langevin, Einstein, Anna Comtesse de Noailles, and Paul Painleve. Those standing are (l. to r.): Thomas Barclay, Leo Strisower, Paul Appell, Émile Borel, and Henri Lichtenberger. The print is adhered to heavyweight paperboard and is signed in pencil by the photographer in the lower right just below the photograph. Also, see EB 186 and EB 205, which are by the same photographer and would appear to have been taken on the same occasion.
