Research Facilities

Closed Laboratories


At the end of his career, Dr. Moor-Jankowski began to doubt the necessity of using primates for experiments.

At one point in its history, the Laboratory for Experimental Medicine and Surgery in Primates (LEMSIP) housed some 300 chimpanzees and nearly 300 monkeys. Chimpanzees and other nonhuman primates were subjected to intensive biomedical research in areas including reproduction, blood transfusions, hepatitis B and HIV.

LEMSIP was established in 1965 with the goal of becoming a federally funded primate research center for the New York area, but it remained a private laboratory until it closed in 1997. The lab, located in a wooded area north of New York City, was affiliated with New York University’s (NYU) School of Medicine.

A paradox in care

Jan Moor-Jankowski, MD was LEMSIP’s founding director and remained in that position until shortly before it closed. Unlike most animal researchers, Moor-Jankowski was willing to interact with those critical of the use of animals. As a result, the lab became well-known to animal protectionists in the 1980s.

LEMSIP’s veterinarian, James Mahoney, had concerns about using animals that led him to encourage lab employees to work towards enriching their lives before enrichment was required.

Yet despite the goodwill towards animal advocates and attempts at humane considerations for the chimpanzees and other primates, the realities of laboratory life were quite cruel. Along with facing the most invasive of biomedical research, chimpanzees at LEMSIP were subjected to a myriad of miserable conditions:

  • Most of the chimpanzees were housed singly in small, steel lab cages that hung above the floor. Moor-Jankowski theorized that allowing feces and urine to fall out of the cages would maintain a healthier environment, rather than hosing down the cages, causing dampness - a contributor to the widespread upper respiratory problems in captive primates. In reality, the cage design caused a permanent foul stench from excrement beneath cages. Even though it was removed regularly from the large plastic sheaths, it still forced chimpanzees to breathe in fetid odors day in and day out.
  • Chimpanzees were denied any outdoor access. Moor-Jankowski believed that this would limit their germ exposure. While his reasoning is suspect, he also apparently gave little thought to how this might affect their mental health or sense of well-being.
  • Adult chimpanzees were given little enrichment.
  • Infant chimpanzees were taken from their mothers and raised by human caregivers to accustom them to being handled for procedures.
  • Chimpanzee mothers were bred repeatedly to churn out babies for research, yet never allowed to raise their children past one year.

Moor-Jankowski and NYU: an escalating struggle

An outspoken man, Moor-Jankowski developed a controversial relationship with NYU, which would eventually have consequences for the primates at LEMSIP.

Beginning in the early 1980s, he was involved in a defamation suit stemming from his role as editor of the Journal of Medical Primatology. Moor-Jankowski permitted the publication of a controversial letter-to-the-editor written by Dr. Shirley McGreal, president of the International Primate Protection League. McGreal’s letter criticized the capture of wild chimpanzees for hepatitis research. This publication caused Moor-Jankowski to come under widespread condemnation from the animal research community.

Later, after NYU withheld funds earmarked for increasing the size of the lab’s chimpanzee cages to comply with regulations, Moor-Jankowski filed a complaint against his employer with the United States Department of Agriculture (USDA) highlighting the deficiencies.

Finally, in the early 1990s, the USDA charged NYU with 378 violations of the Animal Welfare Act at a separate university lab. The charges were in regard to water deprivation and other cruel treatment of monkeys used in addiction experiments. The charges stemmed from Moor-Jankowski having revealed information to the USDA about problems at that lab.

1997: NYU shuts down LEMSIP

In 1995, NYU reacted to Moor-Jankowski and LEMSIP by suddenly announcing that it would close LEMSIP and give all its primates to the Coulston Foundation (Coulston). NYU made this decision with full knowledge that the USDA had filed formal charges against Coulston for the negligent deaths of chimpanzees and monkeys. Soon afterwards, Moor-Jankowski was unceremoniously fired from his position as LEMSIP’s director for 30 years.

More research or the promise of sanctuary?

In 1997, the LEMSIP chimpanzees were sent to Coulston, but not before Jim Mahoney, D.V.M., Ph.D, LEMSIP’s veterinarian and acting director, managed to place 109 chimpanzees and 100 monkeys in sanctuaries around North America, including the Fauna Foundation, Wildlife Waystation and the Primate Rescue Center.

In 2002, most of the LEMSIP chimpanzees sent to Coulston were rescued by the Center for Captive Chimpanzee Care, now known as Save the Chimps, when it took over Coulston. However, an unknown number remain incarcerated in lab cages, transferred to the Alamogordo Primate Facility, which is owned by the National Institutes of Health (NIH) and operated under contract by Charles River Labs.

A change of heart

On August 27, 2005, Dr. Jan Moor-Jankowski died at the age of 81. Personal acquaintances report that he expressed a change of heart about using chimpanzees for biomedical research. A memorial fund has been established by his family, part of which has been designated to donate funds to retirement centers that received the former chimpanzees at LEMSIP. (3)
