Chromatography (TLC) by Kirchner in the U.S. 1952: Martin and Synge receive Nobel Prize for “invention of partition chromatography” or plate theory to describe column efficiency 1966: HPLC was first named by Horvath at Yale University but HPLC didn’t “catch on” until the 1970s 1978: W.C. Stills introduced “flash chromatography”,
