1928 – Bear Exhibits and Monkey House

The old bear pit was filled in and three new bear exhibits were built. They still stand today in the Main Zoo, next to the Administration Building. The comfort station (Exotic Animal House) was changed into a monkey house with big wire cages housing mangabees, macaques and squirrel monkeys among others. Lions, tigers and bears! The historic exhibits located in the center of the Zoo once housed lions, tigers and, yes, a bear!

1950 – Children’s Zoo

The Society decides to build a children’s zoo. During the 1950s-70s, the Brandywine Zoo was converted into a children’s zoo, featuring many fairy tale exhibits and characters.

1952 – Start Building

The ground was broken in 1952. The Wilmington Lions Club was a major fundraiser on the project. There were eleven little buildings, each centering on a different Mother Goose character. All of the exhibits were brightly painted and housed farm animals collected each spring from area farmers willing to donate them. This area was located up in the far section of the zoo to where the picnic area is located. In the first year of the Children’s Zoo there were 46,000 visitors. The themed section survived until the late 1970’s in its original fashion.

1963 – Main Zoo Temporarily Closes

The main zoo had fallen into disrepair and was forced to close while the Children’s Zoo remained open.

1971 – New Castle County takes over the Zoo

Hans Rosenberg was hired as “Zoo Supervisor.” He added to the zoo collection, but kept the Monkey House closed to the public even though animals were still housed there.

1979 – Delaware Zoological Society is Founded

Tom Skeldon took Hans Rosenberg’s place and developed the Delaware Zoological Society. During this time the Administration Building with offices and a kitchen were built. The tiger exhibit was built where an old duck pond had been.

1986 – AZA Accreditation

Improvements were made to the zoo and The Brandywine Zoo became accredited by the Association of Zoos and Aquariums (AZA) and has maintained the accreditation from 1986 to present.
