Yosip Ibrahim

José Alberto Rosciano Holder (1908 - 1992), more well-known under his pen name Yosip Ibrahim, was a Peruvian author and saucerian, noted for his 1972 book "Yo Visité Ganímedes" ("I Visited Ganymede"), in which he related the story of a man called Pepe who was taken to Ganymede, the moon of Jupiter, events that Ibrahim long asserted to be true before eventually recanting in 1992 prior to his death.
