In the early 1980s, University of Oklahoma withdrew its support of the IPS. Faced with the loss of funding, William Lemmon arranged to gradually sell off chimps to a New York University (NYU) biomedical lab, LEMSIP. (Roger Fouts, who had been working with several IPS chimps, had suddenly left for a new position in Washington, taking Washoe and Loulis with him.) Beginning in December 1981, IPS started sending chimps to LEMSIP, including many, like Nim, who had been used in sign language research. Staff at LEMSIP began noticing the chimps using ASL to communicate with them, so vet James Mahoney posted signs around the facility to help the staff understand the chimps' gestures.
