[...] on 3 December 1967 - the heart of a 26-year-old road accident victim, Denise Darvall, started to beat inside the chest of a 54-year-old grocer, Louis Washkansky.
News of the first human-to-human heart transplant, led by South African surgeon Christiaan Barnard, made headlines around the world.
Initial reports widely hailed the operation as "historic" and "successful", though Washkansky only survived a further 18 days.
It became one of the most famous events of the 20th Century, on a par with the moon landing two years later.

[...] on Dec. 2, 1982, in the darkest hours of the morning, cardiothoracic surgeon William DeVries, MD, carefully removed the ravaged heart of Dr. Barney Clark—a heart that tore like tissue paper due to years of treatment with steroids—and replaced it with the world's first permanent artificial heart. Known as the Jarvik-7 (named after former U of U physician and inventor Robert Jarvik, MD), this aluminum and polyurethane device was connected to a 400-pound air compressor that would accompany Clark for the rest of his life - all 112 days of it.
