He is Willem Johan Kolff, pioneer of hemodialysis as well as in the field of artificial organs.
He organised the first blood bank in Europe (in 1940). During WWII he developed the first functioning artificial kidney. In 1950 he left the Netherlands, sensing opportunity in the United States. At the Cleveland Clinic, he was involved in the development of heart-lung machines to maintain heart and pulmonary function during cardiac surgery. He also improved on his dialysis machine.
He is considered as the Father of Artificial Organs, and has been regarded one of the most important physicians of the twentieth century. He obtained more than 12 honorary doctorates at universities all over the world, and more than 120 international rewards, among them the AMA Scientific Achievement Award in 1982, the Japan Prize in 1986, the Albert Lasker Award for Clinical Medical Research in 2002 (considered to be the highest honor in American medicine) for his development of kidney dialysis. The nominating committee noted the invention "changed kidney failure from a fatal to a treatable disease, prolonging the useful lives of millions of patients.", and the Russ Prize in 2003. In 1990 he was named by Life Magazine in its list of the 100 Most Important Persons of the 20th Century. He was a co-nominee with William H. Dobelle for the Nobel Prize in Physiology or Medicine in 2003. Robert Jarvik, who worked in Kolff's laboratory at the University of Utah beginning in 1971, credited Kolff with inspiring him to develop the first permanent artificial heart.
Dr. Kolff once told a reporter his mind rarely took a rest from the mechanics of medical-device designs and how they could save or improve lives. "I nearly always do something. I can't bear to just lie in the sun. It would drive me crazy," he said. Researchers at the U. during his tenure there reported it wasn't unusual to see him there at work any time of the day or night. As a young man, Dr. Kolff worked with his hands as a carpenter on weekends, finding solutions to challenges that would provide the foundation for his future work with mechanical devices.
He died three days short of his 98th birthday on February 11, 2009.
