Kenwa Mabuni
Matsumura taught his art to Itosu Ankō (1831–1915) among others. Itosu adapted two forms he had learned from Matsumura. These are "kusanku" and "chiang nan". He created the "ping'an" forms (""heian" or "pinan"" in Japanese) which are simplified kata for beginning students. In 1901 Itosu helped to get karate introduced into Okinawa's public schools. These forms were taught to children at the elementary school level. Itosu's influence in karate is broad. The forms he created are common across nearly all styles of karate. His students became some of the most well-known karate masters, including Gichin Funakoshi, Kenwa Mabuni, and Chōki Motobu. Itosu is sometimes referred to as "the Grandfather of Modern Karate."
