Patent holder profile

Lloyd A. Hall and the food-preservation patent trail

Hall's profile reads food chemistry and industrial chemistry through patent records that name co-inventors and corporate assignees, not as a solo folklore shortcut.

Why this belongs on CultureUp

Hall is a public-record memory story.

This belongs on CultureUp because the patent record connects invention to place, public institutions, work systems, laboratories, employers, federal or corporate assignment, and the limits of public records.

Sprint 6 priority 1 / not final rankStatus: source_reviewedSource grade: B+

Patent: 1882834 / 2107697: Asphalt Emulsion and Manufacture Thereof; Sterilizing Foodstuffs
Issue date: 1932-10-18 / 1938-02-08
Place: Chicago, Illinois
Record strength: Patent-record facts are attached with at least one public context source. CultureUp still separates patent proof from biography, adoption, commercialization, and identity claims.
Identity evidence: Public context source attached where available; CultureUp does not use the patent row alone as race, ancestry, lineage, or Indigenous Black identity proof.
Sprint priority: 1 / not final rank
Cluster: Food chemistry and preservation
Co-inventors: Edwin E. Mortell, Carroll L. Griffith
Assignee: J. W. Mortell Co.; Griffith Laboratories / corporate assignees
Needed before promotion: Promotion language should remain limited until source-led context, assignment, co-inventor, and commercialization review is complete.
Why this record matters: Hall's records help CultureUp connect Black patent memory to food preservation, sterilization, emulsion systems, laboratory work, and corporate assignment without flattening the team record.

Article profile

Read the person, place, invention, and record separately.

CultureUp keeps each layer visible so a patent record does not get stretched into claims the source trail cannot support.

The patent record

1882834 / 2107697 was issued on 1932-10-18 / 1938-02-08 for Asphalt Emulsion and Manufacture Thereof; Sterilizing Foodstuffs. The route preserves Edwin E. Mortell, Carroll L. Griffith as co-inventors. The route also names J. W. Mortell Co.; Griffith Laboratories as corporate assignees, because inventor status and assignment are different public-record facts.

The person in the record

The attached public context sources support a reader-facing profile frame. Any deeper life history, family record, school record, employment file, or community memory needs its own source trail.

Place attached to the claim

Chicago, Illinois is the public place anchor used for this route. CultureUp does not infer local family continuity from the patent row alone.

The invention

The invention is summarized from the public patent title and source trail. Technical, market, institutional, and adoption claims stay limited to what the attached sources can support.

Business, labor, and use

Modern patent records often separate inventor, employer, assignee, licensee, and beneficiary. CultureUp keeps those categories apart instead of treating a patent as proof of ownership, wealth, adoption, or public impact.

What the record cannot prove

The patent record does not by itself prove full biography, race, ancestry, Indigenous Black identity, commercialization, institutional adoption, economic benefit, modern product lineage, or community memory.

Identity and correction note

CultureUp treats this as Black American patent memory only through public, reviewable sources. The page does not certify ancestry, descent, tribe, nationality, family history, or private identity.

Send stronger patent images, assignment records, employer records, licensing documents, public biographies, or source corrections through CultureUp's correction path.

Patent records do not prove final rank, private identity, solo credit when co-inventors appear, employment ownership, commercialization, adoption, or later public impact.

Indexable as a source-led Sprint 6 profile with visible source limits.

Employer, assignee, and inventor status are not interchangeable. CultureUp names assignees when the patent record does.

Do not use this page to make absolute first, ownership, adoption, or commercialization claims without a separate source trail.
