Dr Ralph I. Lipman is a Stress Physiologist who invented the book light in 1951.

He did research together with Dr. Matthew N. Levy in how the autonomic nervous system influences the heart's force of contraction to help regulate blood pressure.

He used his gastrointestinal research background, in the laboratory of Dr C.S. Tidball, to later help develop some Biomathematical foundations to understand what factors are important in determining if a given generic drug is equivalent to the original brand name product. Thus he was one of the professionals that helped start reducing the cost of prescription drugs.
