10. Organ transplants. In 1954, Dr Joseph Murray removed the kidney from one human patient and implanted it in another. The recipient accepted the kidney as its own rather than rejecting it as a foreign body. It was more than skillful surgery: Murray had chosen a pair of identical twins, Ronald Herrick and his terminally ill brother Richard, in hopes their similar genetic makeup would reduce the likelihood of Richard’s body rejecting Ronald’s liver. Soon afterward, though, other researchers developed drugs that could squelch a transplant recipient’s immune system long enough for the new organ to become incorporated into its new body. Today, some 25,000 Americans a year receive a new heart, kidney, liver, lung, pancreas or intestine — and a new lease on life.
9. Robots and artificial intelligence. The term “robot” was coined by Czechoslovakian playwright Karel Capek in 1920 — “robota” being a Czech word for tedious labor — but the first real industrial robot was built in 1954 by George Devol. Five years later, the Massachusetts Institute of Technology founded its Artificial Intelligence Laboratory in a quest to mechanically mimic human minds as well as hands. Today, robots assemble products better, faster and often cheaper than manual laborers, while more than 8 million U.S. airline flights a year are scheduled, guided and flown with the superhuman assistance of advanced software. Still, some Americans eye such systems with the cynical view of novelist Kurt Vonnegut, whose 1952 story “Player Piano” warned that the machines might leave people without a purpose — or a job.
