Who invented the book light?

Dr. Ralph I. Lipman, Stress Physiologist, at the age of 11 in 1952, converted an early dry cell flashlight into a two part book light. The switch and power were from the remains of the flashlight, and the removed bulb was clipped to the top of the book binding. The bulb illuminated the open pages and was connected by two flexible copper wires to the switch remaining on the old flashlight cylinder. That cylinder containing weighty batteries lay securely on the bedding or nightstand. Thus the illuminated book could be moved around accommodating the reader's position in bed or on a nearby chair. Lipman never patented his new light because he chose to use the necessary funds for his education.
