Ludlow Griscom (June 17, 1890 – May 28, 1959) was an American ornithologist known as a pioneer in field ornithology. His emphasis on the identification of free-flying birds by field marks became widely adopted by professionals and amateurs. Many called him "Dean of the Birdwatchers." ==Early life and family== Griscom was born in New York City, the son of Clement Acton Griscom Jr. and Genevieve Sprigg Ludlow. Ludlow's grandfather Clement Acton Griscom Sr. was a prominent merchant and shipping executive. His maternal grandfather, William Ludlow, distinguished himself through military service. Griscom's family traces its ancestry back to Thomas Lloyd, a 17th-century physician in Pennsylvania. The oldest of three children, Ludlow Griscom had a sister, Joyce, who died in childhood, and a brother, Acton. As a boy, Ludlow's interest in birds showed itself as early as 1898. In 1907, he found fellow nature enthusiasts when he joined the Linnaean Society of New York. Griscom received an A.B. degree, with a major in pre-law, from Columbia University in 1912.〔 Despite initial resistance on the part of his parents, he entered Cornell University as a graduate student of ornithology, studying under Arthur A. Allen. Louis Agassiz Fuertes was one of his neighbors, and they became good friends. Griscom's master's thesis dealt with field identification of ducks of the eastern United States, and he received his A.M. degree from Cornell in 1915. He taught there and at the University of Virginia, and continued to study toward a doctorate. However, financial pressures prevented him from completing that degree, even though his father ultimately consented to his career choice. Griscom married Edith Sumner Sloan on September 14, 1926; the couple had three children, Edith Rapallo, Andrew, and Joan Ludlow.〔 Griscom was an enthusiastic opera- and concert-goer and accomplished pianist. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ludlow Griscom」の詳細全文を読む スポンサード リンク
