Eye surgeon, born 1807, took his medical training at the University of Leipzig. From Germany he emigrated to England establishing his practice at Brighton, where he worked for some 30 years. He was the author of writings on medicine, particularly on the use of baths in treatment of illness. Two of his works were written for the public: The Eye and a Critique on the Art of Preserving the Organ, London, 1839, and Memoirs of the Case of a Gentleman Born Blind and Successfully Operated at the Eighteenth Year of His Age. Physiozogical Observations and Experiments. The latter appeared in Philosophical Transactions, Vol. Vl, 1841, pp. 59-68. It is probable that Rudolf Steiner's reference to the man who had been born blind is taken from this second work of Dr. Franz.
