Who were the numbered SRI remote viewers?

Filed 2026-09-04. This review compares the numbered viewers in SRI's 1987 feedback and precognition experiments with a companion photon-production report, later hypnosis reports, and Rice University's Edwin C. May archive catalog.

Short answer

Viewer 009 was Gary O. Langford and viewer 372 was Joseph McMoneagle. Rice's catalog states both mappings directly. Viewer 177 was probably G. Scott Hubbard, viewer 807 was probably Ron Cain, and viewer 105 was probably a person cataloged as Ruggeri whose given name began with S. Those three identifications follow a consistent initials pattern across the 1987 report and an adjacent run of named 1986 archive folders, but no public key explicitly equates the numbers with those names.

Viewers 137 and 454 remain unidentified. The reports establish that 137 was a woman who entered as a novice in the fiscal-1986 training group and that 454 was a moderately experienced man. Rice catalogs an undigitized Subject ID Master List that may provide the missing direct key.

Identification status

Viewer	Identification	Status	Documentary basis
009	Gary O. Langford	Direct	Rice catalog title: "Remote Viewing Experiments-Local PA Sites, Viewer 009 Gary Langford, 1979."
372	Joseph McMoneagle	Direct	Rice catalog title: "Remote Viewing Slides/Photos Experiments, McMoneagle (Viewer 372), 1979."
105	S. Ruggeri	Strong inference	The photon report uses `.rs`; Rice catalogs an adjacent 1986 Ruggeri remote-viewing folder. The first name is not established by the archive record.
177	G. Scott Hubbard	Strong inference	The photon report uses `.hs`; Rice catalogs an adjacent 1986 G. Scott Hubbard remote-viewing folder, and Hubbard's [[../raw/articles/g-scott-hubbard-sri-remote-viewing
807	Ron Cain	Strong inference	The photon report uses `.cr`; Rice catalogs an adjacent 1986 Ron Cain remote-viewing folder.
137	Unidentified woman	Unresolved	SRI calls 137 a female novice in 1988 and moderately experienced in its 1989 three-year report.
454	Unidentified man	Unresolved	SRI calls 454 moderately experienced in 1989 and uses male pronouns.

The session suffixes behave like reversed initials

The December 1987 photon-production report lists viewers 009, 105, 177, and 807. It says each session number incorporates a viewer code and a chronological sequence, then prints these suffixes:

Viewer	Session suffix	Name match
009	`.lg`	Langford, Gary
105	`.rs`	Ruggeri, S.
177	`.hs`	Hubbard, Scott
807	`.cr`	Cain, Ron

The .lg mapping can be checked against Rice's direct identification of Langford as 009. The other suffixes follow the same surname-then-given-name pattern. Rice's catalog places named 1986 remote-viewing folders for G. Scott Hubbard, Ron Cain, Gary Langford, Ruggeri, and Nevin Lantz consecutively in Box 12, Folders 13 through 17. Lantz authored or managed work in this research line, while the other four names align exactly with the four viewer suffixes in the report. The Rice catalog extract preserves the item titles, locations, and direct viewer mappings.

This is strong circumstantial identification rather than an explicit lookup table. The report never says that the suffixes are personal initials, and the catalog record for Ruggeri gives no first name. Calling viewer 105 "Susan Ruggeri" would add a first name that the public archival chain has not established.

Viewers 137 and 454 remain constrained but unnamed

The 1988 hypnosis report pairs viewer 372 with viewer 137. It calls 372 experienced and refers to him with male pronouns. It calls 137 a novice, refers to her with female pronouns, and says she had shown qualitative ability in fiscal-1986 novice training and participated in the fiscal-1987 feedback experiment.

SRI's 1989 three-year hypnosis report describes 454 and 137 as moderately experienced. It uses male pronouns for 454, says he was skilled in self-hypnosis, and records an initially significant post-hypnosis result that did not replicate in the formal test. Neither public report supplies either name.

Nevin Lantz should not be assigned to 454 from the present evidence. His named 1986 data folder sits beside the four folders that match the photon-report suffixes, but he was also an experiment author and no direct source equates him with 454. Viewer 137 was a woman, which excludes Lantz from that code.

Viewer numbers were not permanent personal identifiers

Rice catalogs Langford as viewer 518 in one 1979 tracking series and as viewer 009 in other 1979 and 1981 records. The archive also has a 1993 folder titled "Viewers 105, 137, 177, and 518, Fuzzy Encoding of Response." These records show that a code could persist within a dataset or recur later, but Langford's two numbers warn against treating every viewer number as a permanent identity across the whole program.

The direct key is available only as an archival folder

Rice catalogs a Subject ID Master List in Box 25, Folder 3. The material is open for research, stored off-site, and requires 24-hour notice, but no scan or item-level contents are online. A copy from the Woodson Research Center could confirm 105, 177, and 807 and may identify 137 and 454.

Net

The public record directly resolves 009 as Gary Langford and 372 as Joseph McMoneagle. It strongly supports G. Scott Hubbard for 177, Ron Cain for 807, and S. Ruggeri for 105 through a shared initials convention and the archive's adjacent named folders. It constrains 137 to a female fiscal-1986 novice and 454 to a moderately experienced male viewer, but their names remain open pending the Rice master list or equivalent records.
