English. Christopher Ter-Serobyan

Today, few people have heard of Christopher Ter-Serobyan, but somehow everybody is perfectly familiar with the green colour of the dollar. So the 70s of the 19th century were marked by rapid development of photography. This in turn allowed the counterfeiters and particularly adventurous individuals in the United States to easily reproduce black and white banknotes, in which the green color was applied only at the edges and in a minimum amount. In America, a serious question arose about how to protect their own population from such «dealers». Green paint, incidentally, has already been purchased, so the experts decided to use it as the base color of the national currency. Banknote today is far from being green, rather, a green with a touch of pink, orange and so on.

Meanwhile, the creator of this color, which can not be forged,was a young talented chemist Christopher Ter-Serobyan, who in 1854 was invited to America from Istanbul to make it impossible to counterfeit US dollar. For his work, Ter-Serobian received $ 6,000, which allowed him to continue his training. He became a pharmacist and returned to Istanbul, becoming the main creator of the colors of the American dollar that can not be faked. Today, few people know that the author of this color is an Armenian scientist.

 In general, it should be noted that many elements of the world’s most powerful currency — the dollar, still remain a mystery for many researchers.

 Thus, the very history of the origin of the word «dollar» is much older than the currency itself. Traditionally, the roots of the name of the bill goes to the Czech Republic, where the local currency of a town was called «thaler». Later, the Americans «borrowed» the name from the English: so thalers became «Dalers». But there is another version according to which Americans borrowed the name of the national currency from the Scandinavians. For about the same time, Denmark and Sweden used a coin, called «Daler». However,  neither Thalers nor Dalers were ever «privatized», they were freely traded as a currency, but had not received the status of the national currency.
