New Elephants (1955)
On 31 August 1955 the Indian Elephant cows "Siwa" and "Rani" arrived at the Wuppertal Zoo. Until 2000 Siwa lived in the old elephant house (which was later reconstructed) and reached the ripe old age of 48, which is remarkably old for an Elephant. To many of the visitors she is known as "Grandma Siwa".
The Wuppertal Zoo Society (Zoo-Verein Wuppertal e.V.) was founded on 27 October 1955 to promote the interests of the Wuppertal Zoological Gardens.
