Who? Born…
 Biochemist Casimir Funk estadounidesnse of polish origin, born in Warsaw on February 23, 20, 1967.1884, New York and died in Albany on November

What did he do?


In 1910 he began researching the disease beriberi (affects peripheral nerves and finally, heart failure) . In 1911 he discovered through experiments that a substance found in rice husk, prevented the occurrence of beriberi. A substance that gave the name of “vitamins” (vita: life and amine: necessary for life). Funk concluded that only a small amount of that substance (1 mg) was sufficient to prevent the disease.
He published his findings in 1912 and in 1915 published the famous book called “vitamin”.

The Ice Cream Cone


The fist ice-cream cone was produced in New York in 1896 by Italo Marchiony, who had emigrated from Italy. He was granted a patent in December 1904. As with many great inventions, a similar creation was independently introduced – in 1904 by Charles Menches. He was selling ice cream – in dishes, like all ice-cream sellers at the time – at the St Louis World Fair. So many people were ordering ice-cream that he ran out of dishes. He looked around, and saw a Syrian man selling a Middle Eastern dessert called ‘Zalabia’, a wafer-like pastry sold with syrup. ‘Give me Zalabia’, cried Menches. He rolled up the Zalabia into a cone, scooped his ice-cream onto the top and the second ice-cream cone was born!
