Lyman C. Craig (born 1906 in Palmyra Township, Warren County,Iowa; died 1974) was a chemical researcher who worked atThe Rockefeller Institute for Medical Research from 1933 onward.[1] In 1944 he published a seminal work oncountercurrent distribution, which became an important separation technique.[2] Craig continued to develop the theory, improve the apparatus and devise new applications of the countercurrent distribution into the 1970s.[3] Countercurrent distribution not only proved to be a useful separation technique, it also inspired the development of the field ofcountercurrent chromatography.[4] In 1950, Craig invented therotary evaporator which is a necessary equipment in most chemical labs.[5][6] He also invented theCraig tube, an apparatus used in small-scale chemistry, in particular for recrystallization.[7] He received recognition from his peers and several honors for his scientific accomplishments. He was elected to theNational Academy of Sciences in 1950.[8] He was the recipient of the 1963Albert Lasker Award for Basic Medical Research.[9] He also was nominated for theNobel Prize in Chemistry.[10]
