In 2000, a feisty, 72-year-old disabled cancer survivor named Susan Potter wheeled into the office of Dr Victor Spitzer at the University of Colorado Anschutz Medical Campus and demanded to donate her body to the Visible Human Project. Meaning that she was requesting, following her natural death, for her body to be sawed into thousands of hair-thin sections that would be photographed, digitized, and painstakingly labeled in order to create an immortal online cadaver that could advance medical training and research.
In 2015, Potter passed away from pneumonia at age 87, and during the spring of 2017, her frozen remains were cut into 27,000 slices, each 63-microns thick. As each layer was removed by a seriously sharp carbide blade, a high-resolution image was snapped. The process to create her complete, open-access body map will continue for a year or so, but when completed, Potter’s body will join two previous Visible Humans in becoming the world’s most well-known human forms.
But who was the woman in life? National Geographic has been following Potter and her legacy for 16 years – here is her story.
The Visible Human Project was dreamed up in 1987, but did not get off the ground until 1991, when the National Institutes of Health (NIH) awarded Dr Spitzer and his late collaborator, Dr David Whitlock, a $720,000 grant to begin work.
The goal was to provide a resource that could be utilized to study normal male and female anatomy in greater detail than flesh-and-blood cadavers, which is how researchers and students have examined physical structures for millennia. On top of the obvious limitation of only being usable for a small number of dissections, cadavers are expensive and not always widely available.
After the funding was acquired, Spitzer and Whitlock needed to find a person who would agree to donate their corporeal self to such an endeavor. In 1993, they got lucky. A convicted murderer from Texas donated his body upon his death by lethal injection and was imaged in 2,000-millimeter-thick sections.
Their first female Visual Human came along a year later. A 59-year-old who died of heart disease and was sliced into more than 5,000 slices that were 0.33 millimeters thick.
