The Delaware Museum of Natural History was founded in 1957 by John Eleuthere du Pont near Greenville, Delaware; it opened in 1972 on a site near Winterthur. It is known for its extensive collections of seashells, birds, and bird eggs. The latter is the second largest collection in North America. It is the oldest natural history museum in Delaware. ==History== Starting in childhood, John duPont built a personal collection of seashells, birds and bird eggs. Even before getting a doctorate in natural science in 1965 and writing several books on birds, he became interested in developing a natural history museum. During and after graduate school, DuPont took part in several scientific expeditions to the South Pacific and the Philippines, and is credited with the discovery of two dozen species of birds. At his request, his uncle Henry Francis du Pont provided land across from the Winterthur estate in the Brandywine Valley of Delaware for the museum. The museum opening in 1972 was attended by 200 duPont family members, and representatives of other Northeastern natural history museums. It was the first major museum of natural history opened since 1910.〔 The museum originally was based on duPont's collection of 1,000,000 sea shells and 100,000 bird eggs. The museum emphasizes the ecology of birds and sea life. In early studies, these were used by scientists to measure pesticide contamination of wild species. DMNH is ranked in the top fifteen in the United States for its collections of mollusks and birds, with the second largest collection of birds' eggs in North America.〔("Collections and Research" ), Delaware Museum of Natural History〕 The museum had a major expansion in 2005 to add educational and exhibit space. It has been expanded to include exhibits on dinosaurs, mammals, and Charles Darwin.〔(【引用サイトリンク】title=Permanent Exhibits )〕 Since 1993, the museum has hosted a Dino Days event near Christmas.〔(【引用サイトリンク】title=Dig deeper into the world of dinosaurs )〕 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「Delaware Museum of Natural History」の詳細全文を読む スポンサード リンク
