FREUD WRITES TO THE PHYSICIST LUDWIG HOPF, COMPARING HIS WORK IN PSYCHOLOGY WITH EINSTEIN’S IN PHYSICS.
In the letter, dated 4 December 1925, Freud expresses gratitude for being compared to Einstein: "Naturally, I envy him [Einstein] because of his precision and the capacity to convince of which his thoughts are capable. In our psychological semi-darkness we can neither work nor hope for a similar result" (translated from the original German).
The recipient of the letter, Ludwig Hopf (1884-1939), was a major figure in early 20th-century theoretical physics. Hopf served as an assistant to Einstein at the University of Zurich and co-authored two papers with Einstein.
