[[entity-draper-laboratory|Draper Laboratory]]'s own institutional history
states that the separation from MIT happened in 1973 and describes the
resulting entity as "an independent, not-for-profit corporation" named The
Charles Stark Draper Laboratory, Inc. — after
[[entity-charles-stark-draper|Charles Stark Draper]], the Instrumentation
Lab's founder and, as of the 1969 Pounds Panel report, its director for
"more than 25 years." Wikipedia's Draper Laboratory article corroborates the
same year and legal form. Both sources converge without contradiction, and
this is consistent with — though it does not re-derive — the already
quote-verified MIT Technology Review sentence in
[[claim-mit-1973-divested-instrumentation-lab-as-draper-under-antiwar-protest]]:
"In 1973, MIT severed its affiliation with the Instrumentation Lab (today
it's the Draper Lab, a private entity)."

Draper.com was reached via WebFetch, a summarizing layer, so its wording
above is paraphrase only, not an admissible `source_quote` under this
vault's quote-provenance rule; the year and legal form are recorded as
Tier-3/4-corroborated historical fact, which clears the sourcing floor for
an uncontested date/legal-form claim.

A more precise day-level date circulates in secondary aggregators (some give
"July 1, 1973") but was not confirmed against a Tier 1-2 source this session
— no MIT Corporation minute or articles of incorporation was located or read.
That specific day is `[unverified-quant — needs primary]` and should not be
treated as settled; the year 1973 itself is not in doubt.

This is the outcome the [[claim-mit-1969-pounds-panel-formed-to-study-not-mandate-divestiture|1969
Pounds Panel review]] anticipated as one of several possible paths, several
years before it happened.
