About the Author
CHARLES W. GEHRKE (1917–2009). As Professor and then Professor Emeritus of Biochemistry at University of Missouri–Columbia, Dr. Gehrke authored over 260 scientific publications in analytical chemistry and biochemistry, including a number of books. He was widely known for developing a quantitative gas chromatographic analysis method for amino acids, which, with NASA, advanced the analysis of moon rocks for signs of life. Dr. Gehrke developed many official analytical methods that were adopted by the Association of Analytical Chemists (AOAC) and received numerous awards, including the AOAC Harvey W. Wiley Award.
Drs. Wixom and Gehrke continued to contribute to the advancement of scientific knowledge and education in many ways long after retiring from teaching and research at the University of Missouri. With a great appreciation for history and the groundwork that has been laid for future generations of scientists, they teamed up to produce this book Chromatography: A Science of Discovery. This is their last publication, as they both have passed away. The future of chromatography will benefit from their lifelong efforts.
