This work is from the collection of Dr. Herbert M. Katzin, an ophthalmologist and pioneer in corneal transplant surgery and eye bank research. He was associated with the Manhattan Eye, Ear and Throat Hospital, where he served at various times as director of research for the eye bank, director of the corneal clinic, president of the medical board and chairman of the department of ophthalmology. Dr. Katzin was co-author of the Atlas of Eye Surgery (McGraw-Hill, 1957 and 1962) and the Rehabilitation of a Child's Eyes (Mosby, 1961), among other books. In 1981, he traveled to China to teach surgeons the techniques he developed. The trip became the subject of a documentary film, China Eye.
