Aug 12, 2016 · For the first time, Hammond demonstrated a feasibility of preservation and utilization of cadaveric human organs from “subjects dying from injury and free from disease.”. Hammond warned that the absence of general systemic disturbances is a prerequisite to successful human organ transplantation.
THE HAMMOND STORY. LAURENS HAMMOND. It’s been over 80 years since the world saw the first Hammond Organ, and it all started with a genius named Laurens Hammond. Laurens Hammond was born 1895, in Evanston Illinois. His mother was a unique woman, and sort of an inventor herself. His father was a banker, whose job afforded the Hammonds an ...

Ancient Greek, Roman and Chinese myths feature fanciful accounts of transplants performed by gods and healers, often involving cadavers or animals. While these tales are considered apocryphal, by 800 B.C. Indian doctors had likely begun grafting skin—technically the largest organ—from one part of the body to another to repair wounds and burns.
Italian surgeon Gasparo Tagliacozzi, sometimes known as the father of plastic surgery, reconstructed noses and ears using skin from patients’ arms. He found that skin from a different donor usually caused the procedure to fail, observing the immune response that his successors would come to recognize as transplant rejection.
European doctors attempted to save patients dying of renal failure by transplanting kidneys from various animals, including monkeys, pigs and goats. None of the recipients lived for more than a few days.
Eduard Zirm, an Austrian ophthalmologist, performed the world’s first corneal transplant, restoring the sight of a man who had been blinded in an accident.
Transplant pioneer Alexis Carrell received the Nobel Prize for his work in the field. The French surgeon had developed methods for connecting blood vessels and conducted successful kidney transplants on dogs. He later worked with aviator Charles Lindbergh to invent a device for keeping organs viable outside the body, a precursor to the artificial h...
Ukrainian doctor Yurii Voronoy transplanted the first human kidney, using an organ from a deceased donor. The recipient died shortly thereafter as a result of rejection.
In the late 1940s and early 1950s, a team of doctors at Boston’s Peter Bent Brigham Hospital carried out a series of human kidney grafts, some of which functioned for days or even months. In 1954 the surgeons transplanted a kidney from 23-year-old Ronald Herrick into his twin brother Richard; since donor and recipient were genetically identical, th...
British immunologist Peter Medawar, who had studied immunosuppression’s role in transplant failures, received the Nobel Prize for his discovery of acquired immune tolerance. Soon after, anti-rejection drugs enabled patients to receive organs from non-identical donors.
The first successful lung, pancreas and liver transplants took place. In 1967, the world marveled when South African surgeon Christiaan Barnard replaced the diseased heart of dentist Louis Washkansky with that of a young accident victim. Although immunosuppressive drugs prevented rejection, Washkansky died of pneumonia 18 days later.
As transplants became less risky and more prevalent, the U.S. Congress passed the National Organ Transplant Act to monitor ethical issues and address the country’s organ shortage. The law established a centralized registry for organ matching and placement while outlawing the sale of human organs. More than 100,000 people are currently on the nation...
The beginning. In 1954, the kidney was the first human organ to be transplanted successfully. Liver, heart and pancreas transplants were successfully performed by the late 1960s, while lung and intestinal organ transplant procedures were begun in the 1980s. From the mid-1950s through the early 1970s, individual transplant hospitals and organ ...
The Hammond organ is an electric organ invented by Laurens Hammond and John M. Hanert [6] and first manufactured in 1935. [7] Multiple models have been produced, most of which use sliding drawbars to vary sounds. Until 1975, Hammond organs generated sound by creating an electric current from rotating a metal tonewheel near an electromagnetic ...

Oct 19, 2021 · The history of organ transplantation. Since ancient times, mythology has included tales of creatures made of an amalgamation of others, transferring body parts and skin. In the 1950s, with no other medical options for then incurable diseases, including nephritis, teams of scientists, surgeons, and generous patients started the field of organ ...
Mar 4, 2019 · Background. Organ transplantation (OT) is one of most successful advances in modern medicine. For patients with end stage disease, transplantation most often provides their only chance for survival. Even before the first transplant was performed, it was clear that OT could only be successful with a multidisciplinary approach.
