† Sudan is a dead Female ♀ African savanna elephant (Loxodonta africana), , who died 1947-12-25 at Ringling Bros. and Barnum & Bailey Circus, in United States, .
Sudan was born wild 1936 at Africa unspecified location, captured 1936 .
There were only two on circuses, both with RBBB. Very few zoos had them at the time - -per my hurried count, Bronx had (1), Philadelphia (1), National zoo (1), Cincinnati (1), and Brookfield (4). I cannot imagine one of these zoos loaning an African to Firestone at the World’s Fair. Besides some of the zoo Africans were old and hardly tractable.
"These so-called pygmy elephants were obtained by Howard Bary around the end of 1935 or early in 1936. He got them for RBBB from the elephant training station at Gangala na bodio in the eastern Belgian Congo (now Dem. Republic of Congo). This litho shows the number of elephants (5) that he took out of the Congo. It was an arduous journey involving an overland trek from Gangala to Juba, Sudan on the Nile, then down the Nile to Alexandria and thence by ocean vessel from there. Two of the elephants died en route. Three arrived in New York for the opening in the Garden in 1936. They were a male “Congo”, female “Pouquois (Puqua)” and another female “Sudan.” The first two were genuine forest elephants (Loxodonta cyclotis) with the straight down tusks, typical of that Species (It is now classified as a separate Species instead of a jungle version of the big bush elephants). The third one, Sudan, was a bush elephant and later photos of her show the physical features of that Species as contrasted to the forest elephants. She lived the longest dying in Sarasota at the end of 1947 (There are some rumors that she was killed). Congo had died in Sarasota in early 1937 and Puqua died in Atlanta in November 1941 in the infamous elephant poisoning incident."
