Beckett, Andy. Pinochet in Piccadilly: Britain and Chile's Hidden History. United Kingdom, Faber & Faber, 2003, covers this subject well. On the transfer of Chilean ideas to the UK and the US, see this article: Kemmerling, Achim, and Makszin, Kristin. "Repackaging in South–North Policy Learning: The Chilean Model of Pension Reform as a Lopsided Exportschlager." Journal of Comparative Policy Analysis: Research and Practice, Routledge, May 2023, pp. 1–18, available here.

This fascination with Chile among the British neoliberal circles is also discussed in this excellent work: Ledger, Robert. Neoliberal Thought and Thatcherism: 'A Transition From Here to There?'. United Kingdom, Taylor & Francis, 2017.

In addition to Andy Beckett's already-cited book, Alan Walters is well-covered in Saith, Ashwani. Cambridge Economics in the Post-Keynesian Era: The Eclipse of Heterodox Traditions. Germany, Springer International Publishing, 2022, p. 258. The book dubs him the "Thatcher Boy in Chile." 

Fernando Flores appears in this video about Erhard and EST: Erhard, Werner. "Werner Erhard and Associates, a Brief Look, 1982, Part 1."

The most famous critique of the kind came from Lucy Suchman. See Suchman, Lucy. "Do Categories Have Politics? The Language/Action Perspective Reconsidered."

Our interview with Joe Truss offers an interesting insight into Stafford's activities in Toronto.

Reid Hoffman, the founder of LinkedIn, is on that list as well. Even though they didn't interact much at the time, Winograd was Peter Thiel's master's course advisor, signing his course signup form every quarter (personal communication with Terry Winograd). On Winograd's influence on Silicon Valley, see Fisher, Lawrence M. "Siri, Who Is Terry Winograd?" Strategy+Business, Spring 2017, Issue 86, available here.

This was related to me by Guillermo Toro, who oversaw the administrative side of Cybersyn before and after the coup (sadly, he passed away a few weeks after our interview). Guillermo had kept the keys to the room until he left his job at CORFO. He confirmed that no changes to the room had been made after the coup.
