AI notable figures: which researcher co-authored both the “Handbook of Artificial Intelligence” and the book “The Fifth Generation”?

Introduction / Context:
AI history features several landmark books that shaped research and public understanding. Two such works are the multi-volume “Handbook of Artificial Intelligence” and “The Fifth Generation,” which discussed Japan’s ambitious computer project and expert systems. Identifying the shared author highlights a key historical figure in AI’s development and advocacy.

Given Data / Assumptions:

• We seek a researcher who appears as a co-author on both titles.
• The timeframe spans late 1970s to early 1980s AI literature.
• Options include distractors not associated with both works.

Concept / Approach:
Edward A. Feigenbaum, often called the “father of expert systems,” co-edited/co-authored the “Handbook of Artificial Intelligence” and co-authored “The Fifth Generation” (with Pamela McCorduck). Other listed names either contributed to AI differently or are not associated with both books. Bruce Lee is unrelated to AI; Randy Davis is a noted AI researcher but not co-author of both titles; Mark Fox contributed to knowledge-based systems but not to both of these specific works.

Step-by-Step Solution:

Verification / Alternative check:
Bibliographic records for both works list Ed Feigenbaum among the authors/editors, confirming the choice.

Why Other Options Are Wrong:

Common Pitfalls:
Confusing editorial roles with unrelated AI texts; ensure both titles match the same person.

Final Answer:
Ed Feigenbaum
