Derald George Langham (May 27, 1913 - May 10, 1991) was an American agricultural geneticist, sesame researcher, and founder of the Genesa Foundation. He is known as the "father of sesame" in the Western Hemisphere for his basic research on the genetics of sesame. Most of the sesame lines grown in the Americas came from his breeding work. Sesame plants are a rich source of vitamins and minerals, and Langham focused on cross-breeding the plant into more fruitful versions. He also attempted to look for other uses of sesame beyond a mere food source. Derald Langham is less known for his genetic work in corn and beans. The Rockefeller Institute in Mexico incorporated his varieties into their materials and his genes are carried on in almost every corn hybrid used in the world. == Family and education == He was born on a farm in Polk City, Iowa, where his interest in plants and animals was piqued at an early age. Langham attended Iowa State College and studied agronomy, where he met the head of the Genetics department, Dr. Ernest W. Lindstrom. Lindstrom encouraged him to pursue his interest in genetics, and he continued his studies under Professor Rollins A. Emerson at Cornell University.〔Olwell, Carol. ''Gardening From the Heart: Why Gardeners Garden''. Derald Langham, Gardening in Circles. pp. 141–152. 1990〕 Langham received his first Ph.D. in Genetics in from Cornell University in Plant Genetics in 1939, and his second Ph.D. in humanities in 1969 from United States International University in San Diego. He later taught at Yale University after spending a number of years in Venezuela, and finally settled his family in Fallbrook, California. He had four children with his wife Margery "Maje" Langham - Jeri, Ray, Lisa, and Tina. 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「Derald Langham」の詳細全文を読む スポンサード リンク
