Yusuf İsmail

Yusuf İsmail, also known as Youssouf Ishmaelo, was a Turkish professional wrestler who competed in Europe and the United States as Yusuf Ismail the Terrible Turk during the 1890s. During his lifetime, native Turks knew him as Şumnulu Yusuf Pehlivan. However, writer Rıza Tevfik posthumously awarded him the honorific Koca ("Great"), and thus he was later remembered as Koca Yusuf.
