What does 'Cahit Arf' mean?

Cahit Arf is a famous Turkish mathematician (1910-1997).

Professor Ikeda says :

"To every problem, he has his own idea of approach. The characteristic of his approach is thoroughness; he always seeks invariants, and prefers explicit constructions rather than combination of existing theories. Once he determines his approach, he energetically tackles the problem and never gives up until he achieves his aim. If one studies Cahit Arf's works, which are full of originality and painstaking computations, one will surely wonder where Arf gets his inspirations, and how he gets insight into most complicated computations."

(Ikeda, PhD)
