Rodolphe Meyer de Schauensee (January 4, 1901 - April 24, 1984) was an American ornithologist. He was born in Rome, and his family moved to the United States in 1913. He was curator of birds at the Academy of Natural Sciences in Philadelphia for nearly fifty years. He was particularly noted for his study of South American birds. He expanded the Academy's collection of bird skins, taking part in collecting trips to Brazil, Thailand, Burma, southern Africa, the East Indies and Guatemala. Ornithology (from Greek: , , ornis, ornithos, "bird"; and , logos, "rationale" or "explanation") is a branch of zoology that concerns the study of birds.
