In the North American Regional Studbook for the Asian Elephant, this location is named as "Seabury" but no further information is provided.
"Charles Ward Seabury was a successful (wealthy) insurance man who donated $35,000 to build the Children's Zoo at Brookfield. My guess is he would donate the funds to buy the baby elephants. Maybe some bookkeeping thing said they came from him. I don't think he had a private zoo." //Jim Alexander
The Seabury Foundation was established in Chicago, Illinois, in 1947 by Charles Ward and Louise Lovett Seabury. Early interests of the Foundation included the major cultural and civic institutions in Chicago, educational opportunities for those who could not afford them, conservation of animals and their habitats, ground-breaking medical techniques, health care for the poor, and recreational and character-building opportunities for city children. http://seaburyfoundation.org/
