Adele Goldberg (computer scientist)

Smalltalk-80. Goldberg joined Kay's group at PARC in 1973, ran its experiments teaching children to program and co-developed Smalltalk with Dan Ingalls and others. She led the work that released Smalltalk-80 beyond Xerox and co-wrote the books that defined it, and in 1979 she was among those who demonstrated the Alto to Steve Jobs's visiting team. She later co-founded ParcPlace to sell Smalltalk tools.
