An NFPF grant funded preservation of six forensic films by Dr. Gradwohl at WashU.
Acetate film requires cold storage near 35 degrees Fahrenheit and 30 percent humidity.
Moving image archivists earn a national median salary near $52,000 annually.
Six short reels shot by Dr. Rutherford Birchard Hayes Gradwohl sat in fragile condition until Washington University's Film & Media Archive completed their preservation with support from a National Film Preservation Foundation grant. Gradwohl, an 1898 graduate of the WashU School of Medicine, founded modern forensic science, ran a St. Louis crime laboratory and school, and trained hundreds of pathologists nationwide. He was also, notably, an amateur filmmaker, using a home camera to document lab techniques and daily casework decades before institutional archives thought to collect such material.
That gap, between what gets formally archived and what actually survives, defines the tension in scientific film preservation. Grant funding is competitive, in-house lab expertise is rare, and cataloging decisions carry real consequences for privacy and access.
For MLIS students, the Gradwohl case offers a concrete look at process, standards, and the MLIS Alumni Career Paths built around this work.
The Gradwohl Films: A Forensic Science Time Capsule
The six reels preserved by the WashU Libraries Film & Media Archive offer a rare, ground-level view of Dr. Rutherford Birchard Hayes Gradwohl (1877-1959), an 1898 Washington University School of Medicine graduate credited with founding modern forensic science. Gradwohl was not a professional filmmaker, but his amateur camera recorded the teaching demonstrations and everyday lab work that shaped early crime-scene investigation in the United States. The result reads less like a formal documentary and more like a working notebook in motion.
From Medical Training to Forensic Leadership
Gradwohl used film for both professional and personal reasons. Some footage shared medical techniques with students, while other reels documented daily activity inside his laboratory. He operated a school and laboratory in St. Louis and founded the city's police research laboratory in 1933. That laboratory helped shift forensic work toward repeatable scientific methods, and Gradwohl's films provided a visual record of the practices he was building.
Six Reels From a Working Lab
According to the WashU Libraries Film & Media Archive, the preservation project completed six short reels of scientific film made by Gradwohl, with support from a National Film Preservation Foundation (NFPF) grant. The reels are not polished institutional productions. They are direct views of laboratory routines and instructional technique, exactly the kind of material that supports history of medicine research into early forensic education.
Why the Reels Read as a Time Capsule
The value of this small collection goes beyond the images themselves. Because Gradwohl made the films for teaching and documentation rather than public release, they can preserve details that formal publications often left out, such as the physical setup of a working laboratory and the way colleagues interacted during demonstrations. For students building MLIS archiving skills, these six reels show how amateur film can function as primary evidence of scientific practice.
A Broader Professional Legacy
Gradwohl's influence reached well beyond St. Louis. He trained hundreds of pathologists who carried his approach across the country, and he helped found professional organizations dedicated to crime science. The preserved reels therefore sit inside a larger institutional story. They are not isolated curiosities; they are moving image records of an educator whose filmed lessons and daily lab life helped standardize the early forensic profession.
Why Amateur Scientific Films Matter to Library and Information Science
What can a short reel shot by a working pathologist tell historians that a published paper cannot? A great deal, and that gap is exactly why moving image archives have become a distinct specialty within library and information science.
Amateur Footage as Primary Source Material
Gradwohl's reels were not made for theaters or broadcast. They were tools: teaching aids for pathology students, records of laboratory procedure, and informal documentation of daily work in a St. Louis crime lab. That is precisely what makes them valuable to researchers now. Published journals show polished conclusions. Amateur film captures method, gesture, and workflow, the tacit knowledge that never makes it into a citation. For historians of science, medicine, and criminal justice, this kind of footage is a primary source in the fullest sense.
A Distinct LIS Specialty
Moving image archival science diverges sharply from studio film preservation. Studio work often centers on well-documented commercial titles with known provenance, rights holders, and distribution histories. Archival work on amateur and institutional film deals with orphaned reels, missing metadata, unstable stock, and unclear intent. The theoretical frame comes from figures like Rick Prelinger and organizations such as the Association of Moving Image Archivists, which treat home movies and industrial film as legitimate cultural heritage rather than second-tier material.
A Rare and Underserved Niche
Forensic and scientific instructional film is an especially thin slice of the surviving record. Most such footage was made in small quantities, stored casually, and discarded once the equipment or personnel changed. Surviving reels are frequently the only visual documentation of specific techniques, instruments, or institutional cultures. When a collection like Gradwohl's comes to light, it fills a gap that no amount of textual research can close.
Documenting Practice and Pedagogy
The Gradwohl films document how forensic pathology was actually taught and performed in the early twentieth century: who stood where, which tools were handled first, how evidence was framed for a camera. That record of professional practice, rather than entertainment, is what LIS professionals in moving image work are trained to identify, preserve, and describe.
Inside the Preservation Process: Grants, Duplication, and Polyester Masters
Preservation work demands both funding and technical expertise, and for small or mid-sized archives, securing either can be the bigger challenge. The National Film Preservation Foundation (NFPF) exists in part to bridge that gap, offering competitive grants that help cover the cost of laboratory preservation for collections held by nonprofit institutions. When Washington University's Film and Media Archive applied for and received an NFPF grant, it enabled the team to send Dr. Rutherford Gradwohl's six forensic science reels through a professional preservation workflow that would have been difficult to fund from general library operations budgets alone.
How NFPF Grants Work for Archives
NFPF grants are specifically designed to preserve "orphan films," moving images that lack a commercial distributor or rights holder willing to pay for their upkeep. Many historically significant scientific, educational, and amateur films fall into this category. The grants typically help fund the laboratory costs of duplication, meaning the archive provides the original elements and curatorial context while the grant helps cover the expensive technical steps. For institutions like university libraries, this funding model is critical: it allows preservation projects that might otherwise sit on a waiting list for years.
The Technical Workflow
Once funded, each reel in the Gradwohl collection would have moved through a standard preservation pipeline:
Inspection: Archivists examine each reel for shrinkage, warping, vinegar syndrome (in acetate stock), or embrittlement, documenting the physical condition before any handling.
Cleaning: Specialized equipment removes dust, mold, and residue without damaging the emulsion layer that carries the image.
Duplication: The original footage is copied onto polyester safety film stock, producing a preservation master intended for long-term storage rather than regular screening.
Access copies: Additional prints or digital scans are generated so researchers can view the content without touching the master or the fragile original.
Why Polyester Is the Archival Gold Standard
Original film stock from the early and mid-twentieth century was typically cellulose nitrate or cellulose acetate. Nitrate is notoriously flammable and chemically unstable; acetate degrades over time through a process that releases acetic acid, giving off a vinegar-like odor. Polyester film stock, by contrast, is chemically inert, dimensionally stable, and resistant to the deterioration pathways that threaten older formats. A properly stored polyester master can remain viable for centuries, making it the preferred medium for any preservation effort aiming to outlast the original material.
For MLIS students considering archives or preservation specializations, including a LOC internship for MLIS students, projects like the Gradwohl films illustrate a core professional skill set: writing successful grant proposals, managing vendor relationships with preservation labs, and making defensible decisions about which materials receive priority treatment.
Chain of Custody and Evidentiary Integrity in Forensic Film Preservation
Chain of custody refers to the documented, chronological record of who held a piece of evidence, when, where, and why, from the moment it was collected through every subsequent transfer. When historical forensic films enter a library or archive, that concept takes on a double life: the footage may once have served as evidence in criminal investigations or medico-legal training, and even decades later its integrity as a primary source depends on how well its history of possession and handling has been recorded.
Legal Chain of Custody vs. Archival Custodial History
In a courtroom, chain of custody exists to prove that physical evidence has not been tampered with. Every handler is logged, every transfer timestamped, every gap scrutinized. Archival custodial history serves a different but overlapping purpose: it traces how a collection moved from its creator to its current repository, noting donors, transferring agencies, and any periods where ownership or location is uncertain. For forensic films like the Gradwohl reels, both layers matter. The footage documents real laboratory and investigative techniques, so its value as a scholarly source rises or falls with the strength of its provenance record. Where documentation is incomplete, archivists are expected to note gaps explicitly rather than leave them unaddressed.
Documenting Every Preservation Intervention
Preservation treatments such as cleaning, inspecting, and duplicating original reels alter the physical or digital state of the material. Current guidance from bodies including the National Institute of Justice1 and the UK Government's Recovery and Acquisition of Video Evidence2 framework stresses that any processing or conversion step must be fully documented so the relationship between the original master and each derivative copy is clear and repeatable. The original master is treated as the definitive copy4: it remains untouched and stored separately from working duplicates1. Integrity verification through cryptographic hashes3, stored apart from the files themselves, provides a technical check that no unauthorized changes have occurred.
Key documentation elements created at the point of collection or accession include:
Accession ID: A unique identifier assigned when the material enters the repository.2
Custodial narrative: A written account of known transfers, with inferred or undocumented segments clearly labeled.
Treatment log: Each cleaning pass, duplication run, or format migration recorded with dates, personnel, and methods.
Hash values: Generated before and after any intervention to confirm the master's integrity.
Why This Matters for LIS Professionals
For MLIS students considering an archival studies degree or preservation careers, forensic film collections illustrate how evidentiary thinking extends well beyond the courtroom. Libraries that receive such materials must distinguish between what is legally verified and what is historically inferred, then communicate that distinction in catalog records and finding aids , a responsibility taught in online master's degree in archives and records management programs , so future researchers understand exactly what they are working with.
Forensic Film Preservation Standards: Environmental Controls and Handling
Nitrate film and acetate film demand different survival strategies. Nitrate stock, common before the 1950s, is chemically unstable and flammable, requiring isolated cold vaults and strict fire suppression. Acetate stock, the safer replacement used in most amateur scientific footage like the Gradwohl reels, still degrades through "vinegar syndrome" if stored carelessly, but it responds well to standard cold storage rather than specialized nitrate vaults.
Temperature and Humidity Benchmarks
The Image Permanence Institute and the International Federation of Film Archives (FIAF) both publish guidance that most academic archives follow. For acetate-based collections, cold storage in the range of 35 to 40 degrees Fahrenheit with relative humidity between 30 and 50 percent significantly slows deterioration. Nitrate materials generally require even lower temperatures, often below freezing, paired with humidity control to prevent both brittleness and chemical breakdown. Archives without dedicated vaults may rely on climate-controlled storage rooms and library environmental monitoring as an interim step while pursuing long-term cold storage solutions.
Handling Protocols on the Bench
Handling reels correctly matters as much as where they sleep. Common practices include:
Gloves: Cotton or nitrile gloves prevent oils and acids from transferring to film base and emulsion.
Inspection benches: Rewind benches with light tables let staff check for shrinkage, splices, and physical damage before any duplication begins.
Odor and condition checks: Regular monitoring for a vinegar-like smell helps catch vinegar syndrome early, since the acidic gases it releases accelerate decay in nearby reels if left unaddressed.
Sensitive Content Considerations
Forensic and medical film, including the kind of laboratory and autopsy footage Gradwohl produced, carries handling considerations beyond chemistry. Archivists often restrict physical access to original reels, route sensitive segments through controlled viewing rather than open digital access, and coordinate with institutional review processes before content reaches researchers or classrooms. This mirrors chain of custody thinking discussed elsewhere in forensic preservation work, treating the film itself as a document requiring accountability at every handling step, not just a historical curiosity.
Cataloging and Access: Describing Forensic Film Collections
Cataloging forensic film pulls archivists and special collections librarians between two competing goals: describing footage richly enough that researchers can actually find it, and protecting the people, patients, and cases depicted from being exposed without consent. Every metadata decision on a collection like the Gradwohl films draws on library science skills and sits on that fault line.
Which Standards Do the Work
The 2012 second edition of Describing Archives: A Content Standard (DACS) remains the backbone of archival description in North America, defining 25 elements with a minimum set of six: reference code, name and location of repository, title, date, extent, and creator. DACS is deliberately format-agnostic, so it does not tell you how to handle a splice, a leader, or a soundtrack. For that, DACS Appendix B points to companion standards: AMIM, the FIAF Moving Image Cataloguing Manual, and the IASA Cataloguing Rules.
Most moving image archives layer a structured schema on top. MODS (version 3.8) handles bibliographic description in XML and supports an accessCondition element for restrictions. PBCore, built for audiovisual material, distinguishes the intellectual asset (pbcoreAsset) from each physical or digital copy (pbcoreInstantiation), which lets you flag a preservation master as restricted while an anonymized access copy circulates freely.
Ethics Baked Into the Record
Forensic and medical instructional film routinely triggers what a 2025 framework calls problematic content: disturbing imagery, denigrating language, compromised privacy, and compromised autonomy. HIPAA identifies 18 categories of protected health information, including faces and voices, that can persist in decades-old footage. Practical responses include tiered access by user type, controlled reading-room viewing, and redacted access copies. Original demeaning or outdated terminology is generally preserved in a controlled descriptive field while contemporary respectful language carries the public-facing record. Human remains footage may also trigger environmental and handling protocols, with reference guidance suggesting 18-20 °C, 45-65 percent relative humidity, and light levels under 200 lux.
Item-Level or Collection-Level
Small archives rarely have the staffing to catalog every reel individually. Smithsonian guidance for audiovisual processing recommends arrangement by functional provenance, describing films in relation to the surgical training program, forensic laboratory, or case files that generated them, rather than as isolated format-based series.3 Collection-level description gets material discoverable quickly; item-level records can be added later for high-value reels, controversial content requiring detailed access notes, or footage tied to specific investigations. Most repositories land somewhere in between, using series-level records with item lists for anything that needs restriction flags.
A Step-By-Step Framework for Libraries Starting Forensic Film Preservation
Libraries holding forensic or scientific film collections can follow a structured workflow to move from discovery to long-term access. This six-step roadmap is scaled for small and mid-sized institutions with limited in-house lab capacity.
What It Costs to Preserve a Small Film Collection
Preservation costs vary widely depending on the scope of work, the format, and whether you need analog-to-digital transfer or full archival duplication. The figures below reflect published pricing from specialized film labs and grant parameters from the National Film Preservation Foundation. For most small library projects, the bulk of lab work is outsourced to a vendor, while in-house staff time for coordination, metadata, and cataloging represents an additional institutional expense that grants typically do not cover.
Project Scale
Typical Preservation Cost
Staffing Need
Typical Timeline
Single 16mm reel, cleaning, splice repair, and frame-by-frame scan (Film Preservation Lab, Preservation tier)
$50 base intake plus $4 per reel for cleaning and archival re-housing, plus $0.98 per foot for scanning
Specialized lab handles intake, quality control, cleaning, splice repair, and scanning. Client library typically assigns one archivist or project manager to coordinate shipping, metadata, and approvals.
Standard (non-rush) scanning jobs at comparable labs complete in several days per batch. Damaged or complex reels require longer turnaround.
Single 16mm reel transfer up to 1 hour (Media Preserve)
Silent transfer: $128 per reel. Sound (optical): $198 per reel. Sound (mag): $260 per reel. HD output adds $32 to $62; 4K output adds $110 to $160.
Lab requires at least one film scanning technician for transfer and output management. Client library needs an audiovisual archivist or preservation librarian to prepare reels, set specifications, and manage file ingest.
Per-reel rates are quoted without a stated turnaround. Comparable labs indicate standard completion in a few days per order, with optional rush surcharges.
Small institutional collection via NFPF Matching Grant
Cash stipends range from $20,001 to $75,000 for laboratory work. Recipients must match at least one fifth of total project costs, covering lab fees, shipping, and related expenses.
Grant applications require an archivist or preservation librarian to prepare the proposal, obtain a lab cost estimate, and coordinate all preservation work. Administrative staff costs are not covered by the grant and must be absorbed by the institution.
Applications due April 2026. Projects must be completed within the grant cycle, which commonly spans 12 to 24 months after award.
The preservation of these films ensures that Gradwohl's techniques, which trained hundreds of pathologists and shaped forensic practice across the country, remain accessible as primary sources of scientific history rather than deteriorating beyond recovery.

Career Pathways in Special Collections and Film Preservation
Hands-on preservation projects, like the Gradwohl forensic science films at Washington University, offer MLIS students a direct entry point into special collections and moving image archivist roles. The salary table below draws on national data from the Bureau of Labor Statistics Occupational Employment and Wage Statistics (2025) to show what professionals in these fields can expect to earn. The archivists, curators, and museum workers group is projected to grow 4 percent from 2025 to 2035, a rate the BLS describes as about as fast as average. The BLS has not yet published a comparable 2025 to 2035 growth figure for librarians and media collections specialists, so that projection is omitted here. With roughly 234,900 professionals employed across the broader librarians, curators, and archivists category, the field is sizable enough to support a range of specializations, from film preservation and forensic collections management to digital access and cataloging.

Choosing an MLIS Program With an Archives or Preservation Focus
Prospective students choosing the right MLIS program and weighing archives concentrations often face a tradeoff between programs with broad, flexible curricula and those offering deep, specialized preservation training. The Gradwohl project shows why depth matters: rescuing scientific film required staff who understood both moving image formats and the historical context of the material, skills that come from targeted coursework rather than generalist electives.
What to Look for in Coursework and Practica
Strong archives tracks pair classroom theory with hands-on access to a preservation lab, ideally one with film inspection benches, cold storage, or digitization equipment. Look specifically for moving image archiving courses, since paper-based archival training does not automatically transfer to film handling. Practicum partnerships matter just as much. A program that places students inside a university special collections department, historical society, or media archive gives students supervised experience with condition assessment, rehousing, and donor negotiations before they enter the job market.
Credentials and Faculty Activity
Beyond the degree itself, students should ask whether faculty are actively engaged in archival science research or grant-funded preservation projects, since that activity often trickles down into assistantships, internships, and letters of recommendation from people doing current fieldwork. Certification from the Academy of Certified Archivists is worth researching separately. It is not a substitute for an MLIS but can strengthen a resume, particularly for applicants aiming at institutions with competitive archivist searches.
Comparing Programs Directly
Because preservation training varies so widely between schools, it is worth comparing specific archives-focused MLIS programs side by side rather than relying on general rankings. Factors like lab access, film-specific coursework, and practicum placements differ enough between institutions that a program strong in digital archives may be weak in analog media preservation, or vice versa. The program comparison pages at mastersinlibraryscience.org let you weigh these details school by school and match a program's actual strengths to the preservation or special collections career you want, helping you choose the best MLIS program for your goals.
