The discovery that beriberi was caused by diet rather than bacteria originated from a laboratory observation of chickens in the Dutch East Indies. Christiaan Eijkman, a Dutch physician and scientist, identified that laboratory birds fed polished rice developed symptoms that vanished when unpolished rice replaced their feed, eventually leading to the identification of vitamin B1.
Early Education and Military Service
Born in Nijkerk in 1858, Eijkman was the youngest of seven children. He attended the Military Medical School at the University of Amsterdam starting in 1875. He trained as a medical officer for the Netherlands Indies Army and completed his doctorate in 1883 with a thesis concerning the polarization of nerves, written while serving as an assistant to Professor Thomas Place.

In 1883, Eijkman moved to the Dutch East Indies, serving as a medical officer in Semarang, Tjilatjap, and Padang Sidempoean. After a period of illness forced a return to Europe, he studied at the Pasteur Institute and Robert Koch's bacteriological laboratory in Berlin. He later returned to the East Indies as part of a mission to investigate beriberi, ultimately becoming the first director of the Dokter Djawa School in Batavia in 1888.
Investigations into Tropical Physiology
During his tenure as director of the Medical Laboratory in Batavia, Eijkman debunked several theories regarding how Europeans acclimated to tropical climates. He demonstrated that blood composition, respiratory metabolism, and temperature regulation did not differ significantly between Europeans and the native population in the tropics, provided the subjects remained free from specific diseases. These findings were published in 1890.
Academic Career and Nobel Recognition
Eijkman returned to the Netherlands to serve as a professor at Utrecht University from 1898 to 1918, eventually serving as the university's rector in 1912. His academic work included teaching physiology, organic chemistry, and conducting research into water pollution and bacteriology. In 1929, he was awarded the Nobel Prize in Physiology or Medicine alongside Sir Frederick Hopkins for his contributions to the discovery of antineuritic vitamins.
