A tour of Carl W. Gottschalk’s collection of historical books reveals the breadth of renal physiology’s history and Gottschalk’s place as a pioneer in the field.
As a child, Carl W. Gottschalk loved collecting. He collected stamps, coins, and most notably butterflies. At just 15 years old, he discovered a rare butterfly species that now bears his name, Stryman cecrops Gottschalki, and published his first scientific paper. His passion for collecting eventually took backstage to his interest in science. As an adult, Gottschalk made innovative advancements to kidney micropuncture and fundamental discoveries of kidney function that shaped the field of modern renal physiology. It wasn’t until many years later that his passion for collecting was reignited by his friend and colleague, Jean Oliver, MD, a renal anatomist and pathologist.
This time though, instead of butterflies, Gottschalk collected historic texts containing hand-drawn illustrations from ancient anatomists dating as far back as the 1500s. On November 25, 2024, students, postdocs, and faculty from the Department of Cell Biology and Physiology, and the invited speaker for the 24th annual Gottschalk Lecture, Samir Parikh, MD, from the University of Texas Southwestern Medical Center, got a peek inside Gottschalk’s historic collection of books in the Wilson Library at the University of North Carolina at Chapel Hill (-CH).

Some books within the collection, including one from Bartolomeo Eustachii, an Italian anatomist from the 1500s, boasted realistic illustrations of the human kidney. Other books, such as one from Andreas Vesalius, an anatomist from the 1500s, who is often referred to as the father of human anatomy, took more creative liberties in depicting a surgical procedure as a show. Nestled among these 16th century texts are more recent manuscripts from the 1940s, including one from Jean Oliver, MD on the architecture of the kidney in chronic Bright’s disease and another from W.J. Kolff, PhD, on the artificial kidney.
The collection was donated to the library by Susan Fellner, MD, a nephrologist and Gottschalk’s wife. Fellner attended the tour and shared anecdotes about the collection, including a touching story about one of the texts on display, a copy of the 1967 report from the Committee on Chronic Kidney Disease chaired by Gottschalk. “Carl was chosen [to lead the committee] because he was so fair and softspoken and could make things happen,” said Fellner. In the document, the committee concluded that people with chronic kidney disease could be treated successfully with dialysis and that no one should be denied this treatment for financial reasons. This document proved critical in later efforts passed into law in 1972 entitling individuals with end-stage chronic kidney disease to dialysis under Medicare.

“I met Carl at the Mont Desert Island Biological Laboratory at Homer Schmitt’s Symposium. A week later, at the University of Chicago, I received a copy of this [report] from Carl. It was my first love note,” said Fellner. “Written across the front was, ‘You will be interested in this, fondly.’ I think that is as unique a correspondence between people newly met that you could imagine,” continued Fellner. The story personifies their meeting of minds and shared passion for renal physiology. Researchers can explore more historical books and illustrations from Gottschalk’s collection at the Wilson Library. Also on display in the library is Gottschalk’s unique kidney-shaped desk.
Gottschalk started his lab at -CH in 1952, where he made many of his foundational discoveries. Every year the Department of Cell Biology and Physiology and the Kidney Center invite a notable leader in kidney research to talk about their research. In the 24th annual Gottschalk Lecture, Samir Parikh, MD, discussed ways to turn back kidney frailty by targeting metabolism and made several references to Gottschalk. In one such reference, Parikh mentioned he follows Gottschalk’s approach of testing multiple insults in different animal models to understand kidney function and dysfunction. Parikh’s research team found that transient insults cause mitochondrial DNA mutations in the kidney that exaggerate kidney stress responses. He shared findings from his team that suggest that augmentation with the coenzyme nicotinamide adenine dinucleotide may enhance kidney resilience to transient stressors and that restoring ATP building blocks may counteract kidney frailty caused by mitochondrial DNA mutations. “Carl Gottschalk painstakingly demonstrated how urine can be concentrated relative to plasma. This is fundamental to terrestrial life,” wrote Parikh in a social post prior to the event. “What an honor and privilege to be connected with Dr. Gottschalk.”
More on Carl W. Gottschalk
Carl W. Gottschalk is best known for his innovations in kidney micropuncture in the 1950s and for discovering how urine concentrates in the kidney by countercurrrent multiplication. Kidney micropuncture was initially developed by A. Newton Richards and Joseph T. Wearn at the University of Pennsylvania in the 1920s but fell out of favor after World War II for being too difficult. Gottschalk’s innovations in micropuncture revived the technique and cemented its utility for kidney research. Kidney micropuncture allows researchers to access distinct kidney nephrons, tiny but key functional units of the kidney, in vivo. This technique helps researchers better understand kidney function and reveals how the kidney filters and transports drugs and chemicals out of the body.
