John Alden Mason
Mason was born in Orland, Indiana, but grew up in Philadelphia's Germantown. He received his undergraduate degree from the University of Pennsylvania in 1907 and a doctorate from the University of California, Berkeley in 1911. His dissertation was an ethnographic study of the Salinan Amerindian ethnic group of California. He also authored a number of linguistic studies, including a study of Piman languages. His later ethnographic works included studies of the Tepehuan.
The first series of Juan Bobo stories published in the U.S. occurred in 1921. They appeared in the Journal of American Folklore under the title Porto Rican Folklore, and were collected by Mason from Puerto Rican school children. The story collection consisted of 56 "Picaresque Tales" about Juan Bobo, and included such exotic titles as Juan Bobo Heats up his Grandmother, Juan Bobo Delivers a Letter to the Devil, Juan Bobo Throws his Brother Down a Well, and Juan Bobo refuses to Marry the Princess.
