Accomplished biochemists and beloved mentors, Thressa and Earl Stadtman have worked at NIH for more than half a century.

Santiago Ramón y Cajal was the first to describe the nervous system, including neurons, in exquisite detail.  His original drawings, as well as information about current NIH neuroscience, are on exhibit in NIH Building 35, the Porter Neuroscience Center.

Martin Rodbell and his colleagues discovered a mechanism that transformed our understanding of how cells respond to signals. In a series of pioneering experiments conducted at the NIH, Rodbell studied hormones--substances which have specific effects on cells' activity. He won the 1994 Nobel Prize for this work.

In the 1950s, the NIH's Dr. Robert Bowman developed a sensitive instrument called the spectrophotofluorometer, or “SPF”, that allowed scientists to use fluorescence as a way to identify and measure tiny amounts of substances in the body.  This exhibit explores the instrument and its use in scientific studies ranging from anti-depressant medication to AIDS research and the Human Genome Project.
