Joseph Weizenbaum

Joseph Weizenbaum was a computer scientist and longtime MIT professor. He created ELIZA, an early natural-language program whose apparent conversational ability became a landmark in the history of human-computer interaction.

From ELIZA to critique

Users’ reactions to ELIZA contributed to Weizenbaum’s later concern that institutions might overstate what computation can understand or responsibly decide. He developed that critique in Computer Power and Human Reason.

Why this belongs in security history

Security is not only a question of mechanisms; it also concerns the human consequences of automated decisions, trust, and accountability. Weizenbaum’s work provides an important scholarly foundation for those discussions.

In memoriam

Weizenbaum died in Berlin in 2008. MIT and computing historians continue to document both his technical and ethical legacy.
