What's Chief's history how did he become deaf and dumb?

Answer 1

when he was a child, the government showed up to his parents place looking for his father, who was the chief of an Indian tribe, so that they could negotiate a way to either move them or have them sell their land. when the government people said they didnt want to go inside because they thought it was way too hot inside. so then Chief Bromden explains to them that it is cooler than the school he goes to, but then gets completely ignored by the government people. that started everything about people thinking he was deaf and dumb, so he would just not say anything to the point where people really started thinking he was deaf and dumb

Answer 2

Chief was born deaf and mute due to a congenital condition called congenital deafness begening prelingual developmental problems Since he was born deaf, he never learned spoken language, which led to his inability to speak.
