This text is from SUMMIT 2, PP. 32, Joan Saslow, Allen Ascher.
It's an essay about Hellen Keller.
She realized goals no similarly handicapped person had ever achieved - university study, success as a writer, worldwide recognition as a great humanitarian.
Would you please tell me the meaning of the underlined part? Thanks,
'She was successful in activities which no other deaf/blind person had ever done before.'
