From ANIMAL PEOPLE, October 1998:
SAN ANTONIO, Texas– – Fifty-
five stumptail macaques arrived on
September 2 at the Wildlife Animal
Orphanage, after a 35-hour ride from the
Henry Vilas Zoo in Madison, Wisconsin.
Native to Thailand, the stumptail colony is
descended from animals used to breed
research subjects for use by the late Harry
Harlow in his notorious infant deprivation
experiments, conducted from 1936 to 1971.
Remaining property of the University of
Wisconsin Regional Primate Research
Center, the stumptails and two breeding
groups of rhesus macaques had been housed
at the Vilas Zoo since 1963.
The stumptail colony still includes
a 37-year-old female who was among those
transferred out of Harlow’s direct custody.
The arrangement predated a clause of the
American Zoo Association code of ethics,
adopted in 1986, which discourages zoos
from providing animals for research not related
to conserving their own species.
