History

During the first decades of the United States,
Philadelphia Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Sinc ...

, were centers of enlightened thought and scientific inquiry. The increasing sophistication of the earth and life sciences, combined with a growing awareness of the great variety of life and landscape in the American wilderness waiting to be discovered, led a small group of naturalists to establish the Academy of Natural Sciences in the winter of 1812. The academy was meant to foster a gathering of fellow naturalists, and nurture the growth and credibility of American science. They frequently looked to their European counterparts for inspiration and expertise and longed to be regarded as equals. On 25 April 1817 they were incorporated into the society under the title of the Academy of Natural Sciences of Philadelphia by the legislature of Pennsylvania. By 1 January 1818, eight members were published. In 2011, the Academy became affiliated with nearby

Center for Environmental Policy

The Center for Environmental Policy informs and engages various constituents, promotes solutions, and builds public and professional awareness on important environmental topics. Much of its activities focus on public programs and working groups. The center hosts or participates in a number of public programs that are free and open to the public. Urban Sustainability Forums feature panels of local and national experts discussing environmental and sustainability topics as they relate to the Philadelphia region. Town Square, which may feature a panel or an individual, addresses a variety of topics relating to the environment or public science. The center also hosts candidate forums, conferences and workshops. The center acts as a logistical hub for a number of Working Groups organized around sustainability issues. Currently active groups include one for condominium and building co-op owners, a network of faith-based environmental groups, and a forum of senior executives in the private sector.


Ewell Sale Stewart Library

The Library and Archives were established at the Academy's founding meeting in 1812 for the purpose of supporting its natural science research. The library provides online access, services, collections, imaging, and shared resources with other libraries. The library houses nearly 200,000 volumes ranging from works published in the 16th century to current journals and books. Its holdings also include illustrated works from as early as the 15th century, including Konrad Gessner's ''Historia animalium'',

Scientific publications

The ''Journal of the Academy of Natural Sciences'' was the first peer-reviewed publication in the United States devoted to the natural sciences. The first volume was published in 1817. By 1842, it had been superseded by the ''Proceedings of the Academy of Natural Sciences''. The ''Proceedings'' have been published continuously since 1841. The ''Journal'' was reborn in 1847 as a larger-format publication that could accommodate longer articles and

s. The last volume was issued in 1918. The Academy publishes three other series. The occasional series ''Notulae Naturae'' began in 1939 as a means to quickly publish short items, usually not longer than 16 pages on subject areas such as zoology, botany, ecology, geology and paleontology. The ''Monographs'' series, which began in 1935, is composed principally of larger systematic reviews of selected taxonomic groups. The ''Special Publications'' series, begun in 1922, includes works such as biography, taxonomy, historical reviews, and collections surveys.

Exhibits and public programs


Public exhibits

The Academy first opened its collections to the public in 1828. The popularity of its exhibits soared in 1868 with the debut of the world's first mounted dinosaur skeleton, ''
Hadrosaurus ''Hadrosaurus'' (; ) is a genus of hadrosaurid ornithopod dinosaurs that lived in North America during the Late Cretaceous Period in what is now the Woodbury Formation about 80 million to 78 million years ago. The holotype specimen was found in f ...
''. In fact, the size of the crowds flocking to this display prompted the Academy to relocate to its present-and roomier-location in 1876.


Collections and the public

As with most museums in the 19th century, there was little separation of the Academy's collections, which were vital to scientific work, and the public spaces. Not only did this subject the collections to extra wear and tear, but visitors were typically confronted with a bewildering assemblage of specimens with little in the way of supplemental information. Over time, however, museums such as the Academy started to showcase their more popular specimens while sequestering the bulk of the collections. In addition, they spent more effort interpreting their public displays. Museums started to play a more active role in educating the public.


Dioramas

One expression of this transformation was the rise of that icon of natural history museums, the
diorama A diorama is a replica of a scene, typically a three-dimensional full-size or miniature model, sometimes enclosed in a glass showcase for a museum. Dioramas are often built by hobbyists as part of related hobbies such as military vehicle mode ...
. These three-dimensional displays were the virtual reality of their time, providing generations of museum visitors with their only opportunity to experience distant places and exotic wildlife. In 1929 program coordinator Harold T. Green created The Academy's first diorama, depicting rocky mountain goats. Green's work was at first controversial amongst The Academy's staff, due to both the cost and accusations of sensationalism, but proved popular amongst the public. In 1935, the
Works Progress Administration The Works Progress Administration (WPA; renamed in 1939 as the Work Projects Administration) was an American New Deal agency that employed millions of jobseekers (mostly men who were not formally educated) to carry out public works projects, i ...
began providing artists to help work on the dioramas, fueling the exhibits' continued expansion. By presenting the wilderness to the public, dioramas nurtured an appreciation of our natural heritage, which, coincided with the growth of the

in the United States. The Academy currently has 37 dioramas, most of which were installed in the 1930s and 1940s. They feature a variety of animals from Africa, Asia, and North America. Some of these, such as the

. In 2018, under the management of Drexel University, The Academy undertook a high profile series of renovations on some of the older dioramas. These renovations were meant to increase the scientific accuracy of the displays and improve their aesthetics.


Dinosaurs

Another icon of natural history museums is the

'', served as the centerpiece of the Academy's "Hall of Earth History" during the middle of the 20th century. In 1986, the Academy opened a new exhibit, "Discovering Dinosaurs." This was the first large-scale exhibit to incorporate the findings of the " dinosaur renaissance." Instead of cold-blooded and lumbering reptiles, dinosaurs were conceived as active-and possibly warm-blooded-animals more akin to birds than reptiles. In 1979, another type of dinosaur was the subject of an exhibition at the academy when it featured Jim Gary's Twentieth Century Dinosaurs and found that it was an enormous success with the public. This unconventional exhibition for a museum of science that featured contemporary sculpture, which focused upon the subjects of intense scientific inquiry, began a trend among its peer institutions, who then began to invite Gary and several other artists who specialized in scientific topics and subjects to museums that always had shied away from anything identified as "contemporary art" as exhibitions.


Other exhibits

In 1979, the academy also opened "Outside-In", a hands-on children's nature museum. In 1995, it pioneered the hands-on simulation of a dinosaur dig, with its "The Big Dig." Other permanent exhibits include "Butterflies!", a live butterfly zoo, and "Science at the Academy", which showcases current Academy research. The museum also has special, changing exhibits. Recent changing exhibits include "Amazon Voyage: Vicious Fishes and Other Riches", "Frogs: a Chorus of Colors", "The Lewis and Clark Bicentennial Exhibition", and "The Scoop on Poop: The Science of What Animals Leave Behind."


Public programs


Festivals

Four weekend festivals organized around scientific disciplines, are held during the year. Paleopalooza, held in mid-February, features fossil collections and talks by leading paleontologists. Earth Day Festival, held in mid-April, features scientists from the Academy's Patrick Center for Environmental Research. Bug Fest, held in mid August, features entomologists, insect collections and live insects. The Philadelphia Shell Show, held in mid-October, features an international shell market and competitive shell displays.


Programs for adults

The Academy began offering lectures to the public as early as the 1820s. Current offerings include natural history author talks, lectures by scientists, workshops and classes. In addition, the Center for Environmental Policy produces public programs on environmental issues.


Programs for families and children

Since its Nature Club in the 1930s, the Academy has offered programming just for children. Several programs appropriate for different age groups are currently offered. Safari Overnight sleepovers (camp-ins) are held on selected weekends during Fall, Winter, and Spring.
Boy Scouts Boy Scouts may refer to: * Boy Scout, a participant in the Boy Scout Movement. * Scouting, also known as the Boy Scout Movement. * An organisation in the Scouting Movement, although many of these organizations also have female members. There are ...
