Moritz A(Adolph). Jagendorf (August 24, 1888 – January 8, 1981) was an Austrian-American folklore author. Jagendorf was born in Czernowitz, Austria-Hungary. He moved to New York City around the age of 15. He earned his doctoral dental studies degree in 1916 from Columbia University. He helped revitalize the Pi Lambda Phi fraternity by founding the NY Alpha chapter. While practicing as a dentist, Jagendorf's interests remained in the folklore of Europe, Asia, and the United States. He wrote several stories for children based on folktales he had heard from these various cultures.
