Sigmund Freud with some ivy-framed brainiacs

Thinkers galore! Sigmund Freud (front row left) poses with some fellow heavy hitters during a visit to ivy-covered Clark University in Worcester, Massachusetts in 1909. The gathered brainiacs are: Sigmund Freud, G. Stanley Hall, and Carl Jung (front row, left to right); Abraham A. Brill, Ernest Jones, and Sándor Ferenczi (back row, left to right). Sigmund Freud was born in 1856, so he turned 53 the year this photo was taken.

This magnificent time capsule of a photo comes from the Prints and Photographs Division of the U.S. Library of Congress where its digital ID is cph 3b41123.
