An extract of the first 250 words of the full text is provided, because this article has no abstract.

Dr John Luetscher was born in Baltimore, Md, the son of a practicing physician. After attending Princeton University, he entered Johns Hopkins Medical School to follow his father’s footsteps as a physician. He was attracted to the intellectual stimulation and challenge of academic medicine by the Hopkins environment and pursued a research fellowship in physical chemistry at Harvard University after completing his internship. During his fellowship, he was exposed to the rigorous and critical approach to science that was to characterize his entire scientific career. His fellowship work focused on plasma proteins and their participation in salt and water metabolism. He returned to Hopkins to complete his clinical training and in 1942 was offered a faculty position in the Department of Medicine there. In 1948, he left Hopkins to become Associate Professor of Medicine at the fledgling Stanford University Medical School, based at that time in San Francisco, where he joined Dr Thomas Addis, a well-known expert in renal disease. John’s interest in salt and water metabolism was enhanced by the discovery of an adrenal principle, "electrocortin," which had been shown to influence sodium and potassium excretion. This steroid subsequently was named aldosterone, and John, in conjunction with his research associates, Quentin "Chip" Deming and Ben Johnson, was able to isolate aldosterone from the urine of humans with nephrotic syndrome and congestive heart failure.^1,2 He is acknowledged to share the identification of aldosterone with the Taits, Jim and Sylvia Simpson, with whom he also shared the prestigious CIBA (now Novartis) . . .
