Chromatography

ROBERT L. WIXOM (1924-2009). As Professor and thenProfessor Emeritus of Biochemistry at University ofMissouri-Columbia, Dr. Wixom received three teaching awards,including a nomination by MU students for the Conservation Educatorof the Year (1996) for the State of Missouri. He served as adepartmental representative to the Graduate Faculty Senate(1970-1993) and the chair of the Biological Sciences Sector,(1989-1992), which included a key role in three new majoruniversity programs. He was the co-initiator of the UMCEnvironmental Affairs Council, serving as their first chair forthree years (1990-1994). In 2003, he received the EarlhamCollege Outstanding Alumni Award. CHARLES W. GEHRKE (1917-2009). As Professor andthen Professor Emeritus of Biochemistry at University ofMissouri-Columbia, Dr. Gehrke authored over 260 scientificpublications in analytical chemistry and biochemistry, including anumber of books. He was widely known for developing a quantitativegas chromatographic analysis method for amino acids, which, withNASA, advanced the analysis of moon rocks for signs of life. Dr.Gehrke developed many official analytical methods that were adoptedby the Association of Analytical Chemists (AOAC) and receivednumerous awards, including the AOAC Harvey W. Wiley Award. Drs. Wixom and Gehrke continued to contribute to the advancementof scientific knowledge and education in many ways long afterretiring from teaching and research at the University of Missouri.With a great appreciation for history and the groundwork that hasbeen laid for future generations of scientists, they teamed up toproduce this book Chromatography: A Science of Discovery.This is their last publication, as they both have passed away. Thefuture of chromatography will benefit from their lifelongefforts.
