This photograph, titled "Figure 83: Lady Macbeth, ferocious cruelty," was created by Guillaume Benjamin Amand Duchenne between 1854 and 1856. Part of a larger series, *Electro-Physiology*, Duchenne's work used electrical stimulation to study facial expressions and their connection to emotions. This particular image depicts a woman contorting her face into an expression of intense rage, representing the character of Lady Macbeth from Shakespeare’s play. The image's starkness and focus on the subject's facial expression showcase Duchenne's groundbreaking research in the field of photography and the understanding of human emotions.
