"The Natural History of Human Teeth" by JOHN HUNTER (1728-1793)

John Hunter labored long, arduous hours with mind and hand to originally describe the anatomy and classification of the teeth.

He was born near Glasgow, Scotland. His masterpiece, "The Natural History of the Human Teeth", was published in 1771. This publication became the foundation of all anatomical texts on anatomy of the jaws and teeth up to the present time. He was the first to attempt a classification of the teeth and his classification stands today practically as presented by him originally.

DENTAL X-RAY PHOTOGRAPHY PIONEER- Professor Doctor WILHELM DIECK - (Jan.12,1867-Feb.28,1935)

Professor Doctor Dieck developed the first practical technique for dental x-ray photography, making it possible to use this highly accurate diagnostic aid routinely in dental practice.

Born and lived in Germany , he was one of the most important pioneers of x-ray photography. After long and arduous work with primitive x-ray apparatus of that time, he published his x-ray atlas. This atlas is still important in maxillary therapy and medical science dealing with the head. Professor Doctor Dieck is given the credit for having introduced the routine use of x-ray photography into the practice of all dentists, thereby insuring proper diagnosis and therapy.
