Photographer, Prisoner, Polyglot NIDDK's Tjio Ends Distinguished Scientific Career By Rich McManus Today is the birthday of the scientist who discovered, some 42 years ago, the correct number of chromosomes in human cells. If you act quickly, you can honor the man and his accomplishment by viewing a modest exhibit in the Lipsett Gallery in Bldg. 10, just outside Lipsett Amphitheater, before it closes Mar. 3.
There you will find 11
remarkable photographs taken by this son of a professional
portrait photographer, and a brief summary of his scientific
career. The photos document, in plants, insects, mammals and
man, chromosomes frozen at precisely that moment in division
when they can be seen distinctly as separate, wondrous
entities.

Dr. Joe Hin Tjio
stands beside photographs of his remarkable chromosome
studies at the first International Human Genetics Congress
in Copenhagen in 1956. His discovery of the correct number
of human chromosomes led to much scientific excitement and
many invitations to speak and teach.
