A black-and-white photograph showing a man seated at a desk, wearing a large, cylindrical helmet-like device called "The Isolator", designed to eliminate outside noise. The device covers his entire head and includes glass eye pieces and a breathing tube connected to an oxygen tank. He is intently writing with pen and paper, surrounded by early 20th-century office equipment. The scene is described in the caption below the image: "The author at work in his private study aided by the Isolator. Outside noises being eliminated, the worker can concentrate with ease upon the subject at hand."
