A History with Missing Pieces — Beyond the Breadcrumbs

A field can acquire a history that sounds remarkably tidy.

There are pioneers. There are firsts. There are decisive technologies. There are places where something began. Later practitioners inherit a line that seems to run backwards without interruption.

Clyde Street repeatedly made that kind of history harder to tell.

Not because Keith Lyons thought history was unknowable. He kept looking for papers, people, artefacts and institutional traces that could make it more knowable. But each return could change the state of the evidence. A new source could move an apparent beginning. An archive could disappear. A living witness could add detail without settling the whole account. Similar practices could appear in different places without evidence that one had produced the other.

The problem was not that history had become impossible.

It was that the evidence did not justify a finished family tree.

THE EDGE OF THE SEARCH

One warning appears in Keith’s 2015 search for the “godmothers” of performance analysis. Looking for predecessors in women’s hockey in the 1920s, he wrote that he had not been able to find them in the primary sources he had searched.

Later posts widened the visible record, including work by Pauline Hodgson, Anna Espenschade and Nancy Miner, and Keith later acknowledged that he had previously overlooked a 1936 field-hockey paper by Espenschade.

The fuller gendered archive belongs in Who Is Missing From the Origin Story? Here, the point is evidential: an unsuccessful search is not evidence that nobody was there. A history can look complete when the limit of the search has disappeared from the finished account.

The edge of the search is not the edge of the past.

THE BEGINNING MOVES

Keith repeatedly tried to locate beginnings.

In December 2011, he wrote about Hugh Fullerton’s 1910 Inside Game. The route to that article had begun years earlier, when a reference in Lloyd Messersmith’s doctoral thesis led through the Ursinus College Library to an old magazine recovered on microfiche. Keith later described Fullerton’s article and the 1931 Messersmith–Corey basketball paper as foundation or “genesis” documents for performance analysis.

That judgement belongs to Keith at that point in his search.

Clyde Street later gives good reasons not to turn it into an absolute origin claim.

The slow-motion trail makes the problem especially visible. In September 2015, Keith wrote about a 1939 paper by Roy Priebe and William Burton on slow-motion pictures as a coaching device. When he had found it while researching his 1988 book on video, it was the earliest published example he knew. He also knew of Edward Ruffa’s 1935 master’s thesis and wondered whether that might be earlier still.

Then the page acquired a postscript.

Keith found more: a 1936 thesis by Roy Priebe, a 1938 thesis by Harry Bartruff, and a 1929 use of slow-motion film by Earl Hill to demonstrate common errors to aeronautical students.

The historical frontier moved inside the same page.

That did not establish Earl Hill as the inventor of slow-motion learning, or prove that later sporting uses descended from him. It established something more disciplined: “earliest known” describes the evidence currently in view.

The past did not change between the main text and the postscript.

The available record did.

WHEN EVIDENCE DISAPPEARS

Sometimes a historical problem is created not by a newly found source but by a missing one.

Charles Reep is one of the most contested figures in Clyde Street’s performance-analysis history. In 2019, correspondence with Richard Pollard brought Keith back to Reep, Neil Lanham and the history of football analysis.

Reep had kept an archive in a shed at his home. Keith had visited Reep but had not seen the shed himself. A photograph showed the collection. Somewhere within it had been a roll of wallpaper onto which Reep had transcribed his hand notation of the 1958 World Cup final.

By 2019, Keith could write only that there was no record of what had happened to the archive.

That absence has a precise consequence.

It does not prove that the missing material would have supported Reep. It does not prove that it would have undermined him. It does not authorise anyone to reconstruct the contents from memory.

It removes evidence that might have allowed later claims to be tested more closely.

That is different from saying that history is merely subjective. Some questions are harder to answer because the objects that might have constrained the answer are no longer available.

A responsible history has to preserve that state rather than filling the gap with confidence.

WITNESSES ADD A VIEW, NOT A TIME MACHINE

A missing archive can make living testimony unusually valuable.

It can also make the temptation to over-trust memory stronger.

Neil Lanham’s correspondence with Keith shows one side of that boundary. Neil could correct wording, attribution and detail in Keith’s public account. Keith gave Neil’s account space; where he used Neil’s material with permission, Neil’s ownership remained visible. None of that turned Neil’s memory into the final history of Reep, Wimbledon, Watford or computer-supported analysis.

Ian Franks gives another version. Keith introduced Ian’s account of the Centre for Sport Analysis at the University of British Columbia in Ian’s own words. The first-person history supplied people, equipment, institutional detail and coaching problems that an outside reconstruction could not supply in the same way.

It remained Ian’s account, from Ian’s standpoint.

The fuller person relationships belong elsewhere in Clyde Street. For this essay, the historical boundary is enough: testimony can make the record richer without carrying the reader back into the past or adjudicating every competing claim.

SIMILARITY IS NOT LINEAGE

By the later years of Clyde Street, Keith’s history of analysis looks less like a line and more like a landscape.

His 2019 return to Liverpool Polytechnic reconstructed a concentration of sport-science and analysis work around Vaughan Thomas, Tom Reilly, Frank Sanderson and others in the 1970s: links with Everton, football motion studies, hand notation in squash, later computerised notation and an institutional commitment to sport science.

Keith called Liverpool a “take-off moment”.

Again, that is Keith’s historical judgement.

Keith also made the limits of that account visible. His recollection was selective, and he placed Liverpool beside developments elsewhere, including Ian Franks and the work established at UBC.

In Computers in Sport, Keith widened the picture further, moving backwards and sideways into the general history of computing, Soviet cybernetics and the work around Anatolij Zelentsov and Valerij Lobanovskyi, sport informatics in Graz, later microcomputer applications, and biographies of people who carried technical knowledge into sport.

The result did not resemble a single invention story.

Different people were near different technologies. Institutions had different resources. Similar practices appeared in different countries and overlapping periods. Sometimes people met and exchanged ideas. Sometimes the record shows only resemblance and timing.

Keith’s search around Graham Taylor, Reep, Simon Hartley and Watford gives the safeguard in compact form. He noticed resonances between Taylor’s football and the work around Lobanovskyi at Dynamo Kyiv, but described the connection as unwitting and said much more research was needed.

Two practices can resemble one another without one descending from the other.

An earlier publication can precede a later method without causing it.

CHRONOLOGY IS NOT PROVENANCE

Dates matter.

Keith cared about them. He searched for primary sources, followed bibliographies into libraries and microfiche, returned to old papers, contacted people, recorded when material was missing, and changed his account when the evidence changed.

But sequence alone does not establish inheritance.

Chronology can tell us that one document came before another. It cannot, by itself, tell us that the later author knew the earlier work, that one institution influenced another, or that similar practices belong to one intellectual lineage.

This is why the apparent messiness of Clyde Street is useful.

Fullerton matters. Messersmith and Corey matter. Liverpool matters. UBC matters. Reep matters. Soviet and Austrian computing histories matter. So do missing archives, witnesses with situated memories, sources that arrive late and developments whose relationship remains unproved.

The field becomes more historical, not less, when those differences remain visible.

WHAT STATE IS THE EVIDENCE IN?

There is an easy way to misuse incompleteness.

We could say that every history has gaps, so no origin claim matters.

Clyde Street does not lead there.

The missing pieces matter precisely because evidence matters.

What changes is the form of the claim.

Sometimes the responsible sentence is: this is the earliest source I have found.

Sometimes: I have not been able to find the primary source.

Sometimes: this person remembers the event differently.

Sometimes: the archive appears to be lost.

Sometimes: these developments resemble one another, but I do not have evidence that one influenced the other.

And sometimes a postscript has to move the beginning.

That history is less tidy than a clean succession of founders, breakthroughs and descendants. It is also more inspectable.

The past on Clyde Street is not a fixed backdrop. Keith repeatedly re-entered it. A recovered paper, a disputed memory, a lost artefact or an institutional record could alter what the present was entitled to say about its own origins.

Question to carry

When an origin story looks settled, what is the state of the evidence that makes it look settled — and what new source, missing archive, situated witness or unproved connection would make you willing to change the claim?

Publication boundary note

This is a source-led historical encounter, not a definitive history of performance analysis. It does not establish absolute priority, direct lineage, field-wide influence or completeness. Historical judgements made by Keith remain Keith’s; witness testimony remains owned and situated; missing-source states remain visible rather than being silently resolved. The article’s distinct reader problem is how a field history should behave when the surviving evidence is incomplete, distributed or insufficient to establish lineage.
