Story
Washoe became central to sign-language research with chimpanzees and reportedly used many ASL-adapted signs.
The archive records the research claims with caution, avoiding a simplistic claim that she spoke human language.
Washoe is archived because animal cognition history must preserve both evidence and the individual animal life.
