the man who tried to photograph thoughts

Spare a thought for poor Madame Darget. How she must have sighed when her husband bounded over to the sofa in his office where she was attempting to rest. In his hands, he clutched a box of photographic plates.

“I am going to put out the lamp and try to take a fluidic print over my forehead,” Louis Darget later reported himself as telling her. “I will hand you a plate for you to do it as well.”

Dutifully, Mme. Darget held the plate about an inch in front of her face as her husband had instructed and, in the darkness, felt her eyelids droop. She was awakened with a jerk as the cool, smooth plate pressed against her face.
