scientific research or medical use, without knowing about the Visible Human Project. Some people have voiced ethical concerns over this. One of the most notable statements came from the University of Vienna, which demanded that the images be withdrawn with reference to the point that the medical profession should have no association with executions, and that the donor's informed consent could be scrutinised. The 59-year-old female donor remains anonymous. In the press she has been described as a Maryland housewife who died from a heart attack and whose husband requested that she be part of the project. In 2000, Susan Potter—a cancer patient and a disability rights activist—became the third body donor to the project, spending the 15 following years until her death by pneumonia in 2015 as an outspoken advocate for medical education and a mentor of medical students at the University of Colorado. For nearly two decades, National Geographic documented the story of Susan Potter and Dr. Victor M. Spitzer, the director of the Center for Human Simulation at the University of Colorado Anschutz Medical Campus who led the NIH-funded project, releasing a video documentary in 2018. By the time Potter met Spitzer in 2000, she had gone through 26 surgeries and had been diagnosed with melanoma, breast cancer and diabetes: her participation in the Visible Human Project marked a significant departure from the original goals of the project, which up until then had only focused on the dissection and imaging of healthy bodies. Problems with the data sets Freezing caused the brain of the man to be slightly swollen, and his middle ear ossicles were lost during preparation of the slices. Nerves are hard to make out since they have almost the same color as fat, but many have nevertheless been identified. Small blood vessels were collapsed by the freezing process. Tendons are difficult to cut cleanly, and they occasionally smear across the slice surfaces. The male has only one testicle, is missing his appendix, and has tissue deterioration at the site of lethal injection. Also visible are tissue damage to the dorsum of each forearm by formalin injection and damage to the right sartorius from opening the right femoral vein for drainage. The male was also not "cut" while in standard anatomical position, so the cuts through his arms are oblique. The female was missing 14 body parts, including nose cartilage. The reproductive organs of the
