Cahit Arf was one of Turkey's greatest mathematicians. He was born in 1910 in Thessaloniki, which is now a city in Greece. A few years later, his family moved to Turkey. At school, he was very good at mathematics. In 1928, when he was eighteen, he went to Paris to study mathematics. He came back in 1932 and taught mathematics at a high school in Istanbul.

Later, he went to Germany, where he finished his doctorate at the University of Göttingen in 1938. In 1941, he found a new idea in mathematics, and today it is called the Arf invariant. For many years, he worked at universities in Istanbul and Ankara. He died in Istanbul in 1997. Today, his picture and one of his formulas are on the Turkish ten lira banknote.
