Advancements in organ preservation resulted from the collaboration between Alexis Carrel and Charles Lindbergh. Carrel, a renowned surgeon, had developed a technique for preserving organs outside the body. Lindbergh, an aviator, provided financial support and technical assistance to Carrel's research. Together, they developed a perfusion pump that allowed organs to be kept alive for extended periods, paving the way for organ transplantation and other medical advancements.
