George Peabody ( ; February 18, 1795 – November 4, 1869) was an American-British financier widely regarded as the "father of modern philanthropy."
Elizabeth Conrad Hickox (1872- July 19, 1947) was a Wiyot master basket weaver and was considered one of the finest basket-weavers of her time.
 Her baskets differ from other Lower Klamath baskets through her own unique use of shape, technique, color scheme and design.
 Her work is in the collections of the National Museum of the American Indian, the Lauren Rogers Museum of Art, Harvard's Peabody Museum, the University of Pennsylvania Museum, the Field Museum of Natural History, the Southwest Museum of Los Angeles, the Denver Art Museum and the Los Angeles County Museum of Natural History.
The Peabody Museum of Salem (1915–1992), formerly the Peabody Academy of Science (1865–1915), was a museum and antiquarian society based in Salem, Massachusetts.
 The academy was organized in part as a successor to the East India Marine Society (founded 1799), which had become moribund but held a large collection of maritime materials in a museum collection at the East India Marine Hall, built in 1825 on Essex Street.
 The Peabody Museum was merged with the Essex Institute to form the Peabody Essex Museum in 1992.
 The East India Marine Hall, now embedded within the latter's modern structure, was designated a National Historic Landmark in 1965 in recognition of this heritage, which represents the nation's oldest continuously-operating museum collection.
The Croatian Natural History Museum (Croatian: "Hrvatski prirodoslovni muzej" ) is the oldest and biggest natural history museum and the main body for natural history research, preservation and collection in Croatia.
 Located on Dimitrije Demeter Street in Gornji Grad, one of the oldest neighbourhoods of the Croatian capital Zagreb, it owns one of the biggest museum collections in Croatia, with over 2 million artefacts, including over 1.1 million animal specimens.
 It was founded in 1846 as the "National Museum".
 The National Museum was later split up into five museums, three of which were in 1986 merged as departments of the newly named Croatian Natural History Museum.
 The museum contains a large scientific library open to the public, and publishes the first Croatian natural history scientific journal, "Natura Croatica".
Ernest Volk (August 25, 1845 – September 15, 1919) was a German-born archaeologist.
 Volk came to the United States in 1867, and worked for Frederic Ward Putnam of the Peabody Museum of Archaeology and Ethnology for two decades, helping to add to the collection through excavations of Trenton, New Jersey.
 In addition to his specimens at the Peabody Museum, Volk's contributions can also be found at the Field Museum of Natural History and the American Museum of Natural History, as well as at several universities.
 Volk was a curator of a collection he compiled at the World's Columbian Exposition in 1893.
