Willem Johan Kolff was a Dutch physician born in Leiden, Netherlands in 1911. He established the first blood bank in Europe during World War II and conducted experiments on blood purification. This led to his invention of the first artificial kidney, which effectively cleansed the patient's blood by cycling it through the artificial device. In 1950, he emigrated to America where he successfully invented an artificial heart, famously implanting one in a dying calf, which led to the animal's recovery.
