He made the highest contribution of over forty types of Turkish folk tales, to the Typen Türkischer Volksmarchen catalog prepared by professors Pertev Naili Boratav and Wolfram Eberhard. With the mastery and meticulousness derived from his poetic skill, he formed his own unique, fluent narrative style in writing down those tales for children. He was the first author to receive the Children’s Literature Award in 1977 given by the Turkish Linguistics Society for his two volume collection of folk tale books titled “Al’lı ile Fırfırı”. His poems were composed to music by the American composer Prof. Bruce Reiprich. And recorded live on a CD titled Salkım Söğüt, or The Weeping Willow.
