Oliver (chimpanzee)

Oliver (c. 1958 – 2 June 2012) was a former "performing" ape once promoted as a missing link or "Humanzee" due to his (somewhat) unusually human-like appendages and a tendency to walk upright. Despite his somewhat unusual appearance and behavior, scientists determined that Oliver was not a human-chimpanzee hybrid.

Oliver was acquired as a young animal (around 2 years old) in 1960 by trainers Frank and Janet Berger. Supposedly, the chimpanzee had been caught in the Congo. Some physical and behavioral evidence led the Bergers to believe Oliver was a creature other than a chimpanzee, perhaps a human-chimp hybrid: Oliver possessed a flatter face than his fellow chimpanzees; Oliver was habitually bipedal (before being struck with arthritis), never walking on his knuckles like his chimpanzee peers; and Oliver may have preferred human females over chimpanzee females. During a December 16, 2006 Discovery Channel special, Janet Berger herself claimed that Oliver was becoming attracted to her when he reached the age of 16. He eventually tried to mate with her, and it became apparent that Oliver could no longer stay with Janet. She decided to sell Oliver to New York attorney Michael Miller.

In 1977 Oliver's owner, Michael Miller, gave him to Ralph Helfer, partner in a small theme park called Enchanted Village in Buena Park, California, USA, built on the site of the defunct Japanese Village and Deer Park amusement attraction. When Enchanted Village closed later that year, Helfer continued exhibiting Oliver in a new venture, Gentle Jungle, which changed locations a few times before finally closing in 1982. The Los Angeles Times did an extensive article about Oliver as a possible missing link or new sub-species of chimp. Oliver was transferred to the Wild Animal Training Center at Riverside, California, owned by Ken Decroo, but he was allegedly sold by Decroo in 1985. The last trainer to own Oliver was Bill Rivers. Rivers reported problems with Oliver not getting along with other chimps.
