After reading an article by the Dutchman Christiaan Eijkman that indicated people eating brown rice were less vulnerable to beri-beri than those who ate only the fully milled product, he tried to isolate the substance responsible and he succeeded around 1912.

In 1897, Dr. Christiaan Eijkman, a Dutch physician and pathologist, demonstrated that beriberi is caused by poor diet, and discovered that feeding unpolished rice ( instead of the polished variety ) to chickens helped to prevent beriberi.

The following year, Sir Frederick Hopkins postulated that some foods contained " accessory factors "— in addition to proteins, carbohydrates, fats, and salt — that were necessary for the functions of the human body .< ref > Christiaan Eijkman, Beriberi and Vitamin B < sub > 1 </ sub >, Official Web Site of the Nobel Foundation </ ref > In 1901, Gerrit Grijns ( May 28, 1865 – November 11, 1944 ), a Dutch physician and assistant to Christiaan Eijkman in the Netherlands correctly interpreted the disease as a deficiency syndrome, and between 1910 and 1913, Dr. Edward Bright Vedder established that an extract of rice bran is a treatment for beriberi.

Christiaan Eijkman was born on 11 August 1858, at Nijkerk, Netherlands as the seventh child of Christiaan Eijkman, the headmaster of a local school, and Johanna Alida Pool.

In this way medical officer Christiaan Eijkman was seconded as assistant to the Pekelharing-Winkler mission, together with his colleague M. B. Romeny.

This proposal was readily accepted, and Christiaan Eijkman was appointed its first Director, at the same time being made Director of the " Dokter Djawa School " ( Javanese Medical School ) which later become University of Indonesia.

Christiaan Huygens, FRS ( or ; ; 14 April 1629 – 8 July 1695 ) was a prominent Dutch mathematician, astronomer, physicist and horologist.

Christiaan Huygens was born in April 1629 at The Hague, the second son of Constantijn Huygens, ( 1596 – 1687 ), friend of mathematician, philosopher and minor physicist René Descartes, and of Suzanna van Baerle ( deceased 1637 ), whom Constantijn had married on 6 April 1627.

In his 1678 Traité de la Lumiere, Christiaan Huygens showed how Snell's law of sines could be explained by, or derived from, the wave nature of light, using what we have come to call the Huygens – Fresnel principle.

For their ideas on derivatives, both Newton and Leibniz built on significant earlier work by mathematicians such as Isaac Barrow ( 1630 – 1677 ), René Descartes ( 1596 – 1650 ), Christiaan Huygens ( 1629 – 1695 ), Blaise Pascal ( 1623 – 1662 ) and John Wallis ( 1616 – 1703 ).

He was the presenter of the first live transatlantic broadcast from the US via Telstar, the first live telecast from Australia in November 1966, and interviewed South African surgeon Christiaan Barnard by telephone in 1967, within hours of the completion of the world's first heart transplant operation.
