"The Psychological Portrait is a remarkable book in its revelatory power to show us a side of personalities such as Einstein, Freud, Frida Kahlo and Diego Rivera that are rarely seen. It also demonstrates that Sternberger was on the cutting edge of photography by using the insights of psychology to achieve his perceptive portrayals. Had Sternberger not died in a car accident in 1956 at 57 years of age it is easy to imagine how astoundingly influential his work would have been to a new generation of photographers."
