CARL W. GOTTSCHALK

April 28, 1922–October 15, 1997

BY MAURICE B. BURG

CARL W. GOTTSCHALK made critical discoveries in renal physciology and pathophysiology with innovative techniques of micropuncture. One of his earliest findings was definitive proof of how urine is concentrated by countercurrent multiplication. That discovery catapulted him to the front ranks of renal physiologists early in his career. In the following years he made many more important observations about the mechanism of urea excretion by the kidneys, the role of renal nerves in salt and water excretion, urinary acidification, and pathophysiologic mechanisms of acute and chronic renal disease. Because of the brilliance and quality of his research he was widely recognized as a leader in renal research.
