Dr. Otto Loewi was the 1936 Nobel Prize winner in Physiology for his 1921 discovery of the chemical transmission of nerve impulses. This photograph was taken in Woods Hole, Massachusetts, in the summer of 1955. Dr. Loewi was spending the summer at the Marine Biological Laboratory where my uncle had a laboratory. This was outside of Dr. Loewi's summer residence and not far from ours. View full size.
