GCguy - could be time for a hall of fame for chromatographers...
What a good idea.
May I make some initial suggestions?
Obviously Michael Tswett
Then, in no particular order
K.I.Sakodynskii
Hesse
In 1941-42 Hesse filled a glass tube with starch and introduced a stream of nitrogen containing bromine and iodine vapours. The separated brown and blue zones could clearly be observed.
Erika Cremer and Fritz Prior The first gas chromatographic system of 1945-1947
Ray (RPW) Scott
Dr. Scott's activities in gas chromatography started practically at the inception of the technique. He pioneered in the development of high-resolution columns, high sensitivity detectors.
James Lovelock The electron capture detector (ECD) is a device for detecting atoms and molecules in a gas through the attachment of electrons via electron capture ionization. The device was invented in 1957 by James Lovelock and is used in gas chromatography to detect trace amounts of chemical compounds in a sample.
Marcel Golay - Capillary column development
golayjpeg1.jpg (8217 bytes)"Marcel Golay joined Perkin-Elmer as a consultant after a 25 year distinguished career at the U.S. Signal Corps Engineering Laboratories in Fort Monmouth, New Jersey. he was originally trained as as an electrical engineer and mathematician at the Federal Technical University of Zurich, Switzerland. He received his PhD in nuclear physics from the University of Chicago. His connection with Perkin-Elmer was mainly due to to his involvement in the development of an IR detector, originally conceived as an aircraft detecting device, and of a multiple-slit IR spectrometer.
When Golay joined Perkin-Elmer, everybody was excited by the versatility and the incredible separation power of GC; inevitably, he also became involved in various discussions of the new technique, which was a totally unknown field to him. He became intrigued by the mathematics of the separation process, and, being an electrical engineer by training and experience, he tried to interpret it with the help of the Telegrapher's equation used to describe the process in transmission lines. He presented this unique comparison at the GC symposium organised in conjunction with the Spring 1956 National Meeting of the American Chemical Society.
In subsequent months Golay continued to investigate - at first theoretically - the separation process occurring in the packed chromatographic column. To simplify the system, he constructed in his mind a model consisting of a bundle of capillary tubes, each corresponding to a passage through the column packing. These ideal capillaries would be unrestricted by the geometry of the packing or the randomness of the passages through it, which are beyond control. Therefore, the capillaries should behave close to the theoretical possibilities. Golay's considerations were outlined in a number of internal reports, of which the one dated 5 September 1956 was the most important. In this report he suggested some experiments with a capillary tube 0.5 - 1mm in diameter. and wetted with a suitable stationary phase, which corresponded to one of these passages."
Richard Synge and AJP Martin
AJP Martin - Archer John Porter Martin, FRS was an English chemist who shared the 1952 Nobel Prize in Chemistry for the invention of partition chromatography with Richard Synge.
Leslie S. Ettre one of the most prominent persons in the history of chromatography.
John Dolan. Other experts in the field all agree that Dolan has a special gift for understanding and explaining liquid chromatography (LC). "John has an almost unique ability to develop and grasp complex technology, reduce it to practice, and communicate clearly to others how to use it effectively,"
Richard Perkin and Charles Elmer
William "Bill" Redington Hewlett and David "Dave" Packard,
Walter Jennings
These are just some initial thoughts. There are many more who have made, and still make, significant contributions to the further understanding, development, sharing and promotion of chromatography.
For example, Ted Adlard and Alan Handley
