Against Forgetting: The Retired Experts Racing to Document What They Spent Lifetimes Learning

In a converted garage in rural Ohio, a seventy-three-year-old former millwright named Gerald Haas has spent the better part of three years recording himself. Not for vanity, and not for profit. He records because he is one of perhaps a dozen people in the country who still understands how to align and calibrate a particular class of industrial paper-pressing machinery that was common in Great Lakes manufacturing facilities throughout the mid-twentieth century. The machines still exist. The knowledge of how to maintain them, increasingly, does not.

"I kept waiting for someone to ask," Haas said during a recent phone conversation. "Nobody ever asked. So I figured I had to just start talking."

What Haas is doing — filming detailed procedural walkthroughs, narrating his reasoning aloud, annotating hand-drawn diagrams and uploading the results to a modest YouTube channel with fewer than four hundred subscribers — represents something larger than one man's retirement project. It is part of an informal, largely uncoordinated movement of retired professionals across the United States who have concluded that the knowledge they accumulated over decades of practice is not being captured by any institution equipped to preserve it. And so they are capturing it themselves.

The Gap That Institutions Left Behind

American workforce training has long operated on the assumption that knowledge transfers naturally — that apprentices absorb expertise from journeymen, that corporate onboarding fills the gaps, that trade schools and community colleges formalize what experience provides informally. That assumption has grown increasingly fragile. The hollowing of vocational education over the past four decades, the consolidation of manufacturing industries, and the widespread offshoring of specialized production work have severed many of the traditional transmission pathways through which practical knowledge moved from one generation to the next.

What remains is often fragmentary. A retired glass-blower in West Virginia maintains a handwritten notebook of chemical compositions for specialty glass types that she developed through decades of experimentation — compositions she describes as "not in any book I've ever found." A former naval engineer in San Diego has spent two years producing a written and illustrated manual for a type of shipboard mechanical seal repair that, he estimates, fewer than fifty active-duty technicians in the country currently know how to perform correctly. A retired Appalachian furniture maker in eastern Tennessee has been recording himself building chairs using joinery techniques passed to him by a mentor who learned them before the Second World War.

None of these individuals were asked to do this work. None of them are being compensated for it. Most of them describe a quiet, persistent anxiety — a sense that time is running out, and that the window for preserving what they know is closing in a way that feels both personal and consequential.

A Race Measured in Years, Not Decades

Demographers who study skilled labor have long warned that the United States is approaching a knowledge cliff. The generation of workers who entered skilled trades and specialized professions in the 1960s and 1970s is now in its seventies and eighties. Many have already died. Others are in declining health. The expertise they carry — developed through years of hands-on problem-solving in environments that no longer exist in quite the same form — cannot be reconstructed from first principles. It can only be transmitted.

The urgency is not abstract. In fields ranging from historic building preservation to specialty chemical manufacturing, from traditional textile production to analog electronics repair, practitioners and historians have begun documenting instances where specific knowledge has already been lost — where a technique, a material specification, or a diagnostic method simply no longer exists in recoverable form because the last person who knew it is gone.

What makes the current moment distinctive is that the tools for individual documentation have never been more accessible. A smartphone, a decent microphone, and a free video platform are sufficient to create a record that, in principle, could be discovered and used by someone decades from now. The retired professionals doing this work understand that they are not building polished educational curricula. They are building something more like a message in a bottle — imperfect, personal, and offered without any certainty that it will reach the right hands.

The Texture of Irreplaceable Knowledge

What these informal archives tend to capture is precisely what formal documentation misses: the judgment calls, the sensory cues, the accumulated heuristics that experienced practitioners develop over time and rarely articulate explicitly. A machinist does not simply know that a particular cut requires a particular speed — she knows what the sound of the cutting tool should be, what the color and curl of the metal shavings indicate, how the vibration in the machine's frame signals when something is beginning to go wrong. That knowledge lives in the body and in the ear as much as in the mind, and conveying it through video or written description requires deliberate effort and considerable skill.

Many of the individuals engaged in this work describe the documentation process itself as revelatory. Forced to articulate what they have always done intuitively, they find themselves discovering the depth and complexity of their own expertise in new ways. "I didn't realize how much I knew until I tried to explain it," said one retired tool-and-die maker in Michigan who has been producing a series of written guides for an online community of hobbyist machinists. "Some of this stuff, I had to think about for days before I could figure out how to put it into words."

What Institutions Could Learn

The informal documentation movement raises an uncomfortable question for universities, trade associations, museums, and government workforce agencies: why are retired individuals doing this work alone, with personal equipment, on personal time, without institutional support?

Some organizations have begun to recognize the gap. The Smithsonian's Center for Folklife and Cultural Heritage has long conducted oral history work with traditional craftspeople. A handful of state humanities councils have funded targeted documentation projects. Community colleges in several states have experimented with programs that bring retired practitioners into classrooms not as instructors but as living archives — people whose knowledge can be recorded and preserved even if it cannot be fully transmitted in a single semester.

But these efforts remain scattered and underfunded relative to the scale of what is being lost. The informal documentarians filling the gap are doing so because they have concluded — correctly, in most cases — that no one else is going to do it.

Gerald Haas, back in his Ohio garage, is currently filming what he estimates will be his forty-seventh video. He does not know how many people will ever watch it. He knows that his hands are not as steady as they once were, and that there are days when the work is harder than he expected. He does it anyway.

"Somebody's going to need this someday," he said. "Maybe not soon. But someday. And I'd rather it exist than not."

That, in its plainest form, is the logic driving an informal preservation movement that America has barely begun to notice — and cannot afford to ignore.
