Remembering Dr. Steve Ross

It is with the deepest sadness that Lincoln Park Zoo is announcing that Dr. Steve Ross, director of the Lester E. Fisher Center for the Study and Conservation of Apes, died suddenly in the early morning of Wednesday, April 20.

Dr. Ross was a widely respected zoo primatologist who dedicated his life to the care, welfare, and study of chimpanzees. During his life, he helped secure safe homes for countless inappropriately housed chimps, oversaw the zoo’s efforts to conserve chimpanzees and gorillas in the Republic of Congo, and coordinated our work with one of the world’s leading chimpanzee sanctuaries. He conducted hundreds of studies and published widely on a broad range of subjects related to the fields of zoology and primatology.

This is a devastating loss for the entire Lincoln Park Zoo family. We respectfully request privacy for the family at this impossibly difficult time.
