Symptoms of beriberi include muscular atrophy and paralysis. In Dutch colonies in Asia, Christian Eijkmann was given the task of finding the causes of the illness. By chance, he noted that hens that were fed milled rice were afflicted by similar symptoms. Further research led in 1897 to the conclusion that there was a substance in the husk of rice that counteracted the illness. These vital substances came to be called vitamins. The substance that counteracts beriberi subsequently was designated vitamin B1.
Their work and discoveries range from how cells adapt to changes in levels of oxygen to our ability to fight global poverty.
