New People –> People Connections
RAND / Carnegie Mellon AI Cluster (1955–1966)
- Allen Newell + J. Clifford Shaw + Herbert Simon: co-developed Logic Theorist (1956) and General Problem Solver (1957); together created IPL list-processing language
- Newell + Simon: shared Turing Award 1975; both at Carnegie Mellon after 1957
- Shaw: built JOSS time-sharing system (1963) on JOHNNIAC – connected RAND AI work to interactive computing
- Newell + Simon + John McCarthy + Marvin Minsky + Claude Shannon + Nathaniel Rochester: all at the 1956 Dartmouth Conference where “artificial intelligence” was named
- Shaw (IPL) –> McCarthy (LISP): IPL’s list-processing concepts directly influenced McCarthy’s LISP, connecting JOHNNIAC to every subsequent AI language
University of Sydney / SILLIAC Cluster (1952–1968)
- Harry Messel + John Blatt: independently and simultaneously realized Sydney needed a computer (late 1953); joined forces; Blatt contributed scientific case, Messel fund-raising
- Messel + Adolph Basser: Messel secured the AU 50 000 donation that funded SILLIAC
- John Blatt + John Bardeen (PhD supervisor, Illinois): Bardeen was simultaneously inventing the transistor; Blatt’s Illinois connection provided the ILLIAC blueprints
- Bob May + Robbie Schafroth (PhD supervisor): Schafroth died young (1959, aged 34); May’s career shifted from physics to ecology after this loss
Illiac Suite Cluster (1955–1958)
- Lejaren Hiller + Leonard Isaacson: co-composed Illiac Suite (1956); co-authored Experimental Music (1959)
- Hiller + John Cage: collaborated on HPSCHD (1969) at Illinois; Hiller’s probabilistic methods resonated with Cage’s indeterminacy aesthetic
- Hiller (Illiac Suite, 1956) + Max Mathews (MUSIC, IBM 704, 1957): parallel emergence of computer music on IAS-family machines and IBM 704 in the same year
Weizmann / WEIZAC Cluster (extended from existing entries)
- Chaim Pekeris + Gerald Estrin: Pekeris motivated the project; Estrin built the machine
- Pekeris + John von Neumann: von Neumann’s personal endorsement (“Pekeris will use it full time”) was decisive for the project’s approval
- Gerald Estrin –> Vint Cerf (doctoral student at UCLA after WEIZAC): WEIZAC builder directly mentored a father of the internet
New Mentorship / Influence Chains
-
Von Neumann –> Pekeris (IAS experience) –> WEIZAC –> tidal prediction –> amphidromic point discovery: The freely published blueprint enabled Israel to discover a feature of the planet that no one knew existed.
-
Shaw (IPL on JOHNNIAC) –> McCarthy (LISP on IBM 704) –> every AI language since: The IAS-clone JOHNNIAC’s programming language lineage runs to modern AI.
-
May (SILLIAC, 1956 superconductivity) –> May (logistic map chaos, 1974–1976) –> chaos in ecology: The first computation on SILLIAC was run by the person who would later show that ecological systems are inherently chaotic – a connection between the IAS clone era and the chaos revolution.
-
Burks + Goldstine + von Neumann (1946 IAS blueprint) –> 15+ clones on 4 continents: The specific document was a 42-page report; Burks wrote substantial sections; the global spread of computing traces to this single authored document.
Corrections and Clarifications to Existing Entries
-
Barricelli.md: Listed in INDEX.md as an existing file but never created. See Post12_new_people.md for the Barricelli entry. INDEX.md should be updated to point to Post12_new_people.md or a new individual file.
-
JOHNNIAC.md note on Dartmouth: The JOHNNIAC file says “Nathan Rochester” but the post (and standard sources) give “Nathaniel Rochester.” Nathaniel is correct; the JOHNNIAC file has a typo.
-
SILLIAC.md: States Bob May received his PhD “at age 24.” He was born 1936 and received his PhD in 1959 – age 23. The file’s figure of 24 is close but may refer to when he ran the first SILLIAC computation (June 1956, age 20, not 24). This needs verification against primary sources; the post repeats the “24” figure.
-
Post 12 factual flag – “first in Asia”: The post states WEIZAC was “the first computer in the Middle East and the first in Asia.” Israel is geographically in Asia (western Asia / Levant), so “first in Middle East” and “first in Asia” could both be true – IF no earlier machine existed in Japan, India, or China. Japan’s FUJIC was completed in 1956 (after WEIZAC’s late 1955 first run), but earlier Japanese relay computers (e.g., the ETL Mark I relay machine, 1952) likely predate WEIZAC. The “first in Asia” claim needs verification; it may only hold for electronic stored-program computers, and may not hold even then. The “first in the Middle East” claim is uncontroversial and the more defensible formulation.
