In Memory of Roy Eksteen


It is with heavy heart that we remember our friend and colleague Roy Eksteen. Roy passed away unexpectedly on September 21, 2015, on a plane returning home from a hiking and mountain biking trip to Colorado. He was 66 years old.

Roy made many contributions to the field of chromatography. He served on the editorial board of LCGC from 1988 to 2015 and was a board member of the Chromatography Forum of the Delaware Valley from 2010 to 2015. He was active in supporting chromatography conferences, particularly the International Symposium on High Performance Liquid Phase Separations and Related Techniques (HPLC) and the Symposium and Exhibit on the Separation and Characterization of Biologically Important Molecules (ISPPP) through exhibitor-related activities and by serving on organizational committees. Roy was a very social man who often helped connect people working in similar areas. He liked to help scientists with specific separations problems find creative solutions, whether those were already commercially available or still needed to be developed.

Roy grew up in Hilversum, the Netherlands. He received a master’s degree from the University of Amsterdam and then left for the United States to study with Professor Barry Karger at Northeastern University. Roy received his PhD from Northeastern in 1980 working on what would be later called “type B” silica and its use as a support particle in liquid chromatography. He proceeded to work multiple times for both Tosoh Biosciences and Supelco. Roy retired from Supelco on July 1 of this year. In both companies he held various sales and marketing positions and specialized in biomolecule separations. He often traveled for his work and loved interacting with people from all walks of life.

As a hobby, Roy founded Cornerstone Coffee, through which he sold coffee that he roasted himself. He started off small and expanded until he could roast 10 lb of coffee at a time. Roy kept a laboratory notebook to track his roasting procedures and was meticulous in maintaining consistency in his lots. Coffee roasting was a favorite activity of his, and complemented his love of good coffee and espresso.

Roy loved to hike and play sports. He was particularly adept at racquetball, often taking on younger players and demonstrating how the game was played. He loved most things outdoors and took up kayaking and canoeing many years ago. Roy was an avid track and field athlete in high school and specialized in the pole vault. He loved the Penn State football team and loved living in State College, Pennsylvania, where Penn State is located.

Roy is survived by his wife Elena, daughter Sara, and three grandchildren, all of whom he loved greatly. Roy had many friends everywhere and was known for being a fun-loving man with a wonderful attitude who was athletic, curious, and politically aware. Roy had a phenomenal presence and added to any conversation with wit, humor, and insight. We will miss Roy, who was a great man and a great proponent of the chromatographic sciences.
