9676 Eijkman           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Christiaan Eijkman (1858-1930) won the Nobel Prize in physiology or medicine for his discovery of the antineuritic vitamin, now known as B _1 or thiamine. Investigating the disease beriberi in Java, his observations of dietary deficiency led to the discovery of vitamins. He shared the 1929 Nobel Prize with Gowland Hopkins.
