Object typePhotograph
PeriodFrench, 1838, the first year of the publicly announced daguerreotype process

A daguerreotype made from an upper window near Daguerre's own workshop in Paris in 1838, showing a wide boulevard that appears deserted because its exposure of several minutes erased everything that moved through it. In one corner, a shape that held still, a man having his boots polished, and by one later reading a second, blurred figure doing the polishing, are usually credited as the earliest people ever fixed on a photographic plate.

Daguerre gave the plate, with a companion midday view and a studio still life, to Ludwig I of Bavaria in 1839 as a demonstration of his new invention. It reached the Bayerisches Nationalmuseum by transfer in 1868 and remains there, but every source consulted for this record agrees that the original plate was later damaged by a cleaning attempt, and one serious academic source states plainly that it was destroyed, leaving only its frame. The sources disagree by more than a decade on when this happened, and this record has not smoothed that disagreement into a single account.

What most people see when they see this image is not a photograph of the object as it exists today. It is a reproduction of a reproduction, made from a copy negative shot before the damage occurred, of a plate whose two most famous figures have never been named and whose exact damage date is not established in any source this record could verify.

The artist

French · 1787-1851

Louis Jacques Mande Daguerre

Daguerre did not begin his working life as a scientist. He trained in architecture, theatrical design and panoramic painting, and built his reputation and his fortune in the theater before he built it in chemistry. The daguerreotype process that carries his name was developed in a decade long partnership with another man, Nicephore Niepce, whose earlier and more fundamental work is frequently underweighted in accounts that lead with Daguerre's name alone. This dossier follows the documented sequence: theater, partnership, invention, fire, announcement, pension, and only then, the plate this record is about.

Dates and place
Born 18 November 1787 in Cormeilles-en-Parisis, in the Kingdom of France; died 10 July 1851 in Bry-sur-Marne, of a heart attack.5
Training and early career
Apprenticed under the architect and panorama painter Pierre Prevost, and worked in theatrical scene painting and panoramic illusion painting before turning to photography.5
The Diorama
In 1822, with Charles Marie Bouton, Daguerre opened a Diorama theater in Paris built around large, translucent painted canvases lit to produce illusions of changing time and weather. Bouton later withdrew and Daguerre ran it alone; by one account it earned him roughly 200,000 francs a year at its peak.5
Partnership with Niepce
Daguerre entered a formal partnership with Nicephore Niepce in 1829 to develop and improve Niepce's earlier heliographic process. Niepce died suddenly in 1833; Daguerre continued the work alone and, later, in a continued agreement with Niepce's son and heir, Isidore.5
Where this plate was made
The Boulevard du Temple view was exposed from a window near Daguerre's own apartment beside the Diorama building on the rue des Marais, close to the Place du Chateau-d'Eau, an area of Paris that today lies near the Place de la Republique. He photographed his own neighborhood, not a commissioned or traveled subject.4
The Diorama fire
On 8 March 1839, five months before the daguerreotype process was announced to the world, Daguerre's Diorama building burned down, destroying daguerreotype specimens, notes and equipment stored inside it. The scale of what was lost has not been itemized in any source consulted, but the fire is one likely reason so few of Daguerre's earliest experimental plates survive at all.5
The 1839 announcement and the pension
The invention was announced without technical detail on 7 January 1839, to the French Academy of Sciences and the Academie des Beaux Arts. On 19 August 1839 the French government published the full process and declared it free to the world, with one exception: Great Britain and its colonies, where Daguerre had personally registered a patent five days earlier, on 14 August. In exchange for the rights, the French state granted Daguerre a life pension of 6,000 francs a year, and Niepce's heir Isidore a pension of 4,000 francs a year.5
A working inventor's own words
In a prospectus circulated to prospective subscribers in 1838, before the process was publicly disclosed, Daguerre is widely quoted describing his own invention as more than a drawing instrument. The line appears consistently across general histories of photography, though this record has not traced it to an independently verified manuscript source.10
Reputation after 1839
Daguerre did not continue to develop the process commercially himself after the 1839 announcement, and spent his remaining years at Bry-sur-Marne, where he died in 1851. The process that carried his name alone would be substantially superseded within two decades by Henry Fox Talbot's negative and positive process, which allowed multiple prints from a single exposure in a way the daguerreotype, a unique object on a metal plate, never could.25
The daguerreotype is not merely an instrument which serves to draw Nature; on the contrary it is a chemical and physical process which gives her the power to reproduce herself.Attributed to Daguerre's own 1838 prospectus to prospective investors, before the process was publicly disclosed, and widely repeated in general histories of photography. This record has not independently verified the line against a primary manuscript; treat it as a widely quoted attribution rather than a confirmed exact transcription.

A street that looks empty and is not

At first glance the plate shows a wide Parisian boulevard, lined with plane trees and four and five storey buildings, curving away toward a hazy vanishing point, with no one on it at all. That impression is the whole point of the object and the reason it survives in the literature of photography rather than only in a museum store. The Boulevard du Temple, in 1838 one of the busiest streets in Paris, was in fact full of carriages, carts and pedestrians at the moment the plate was exposed. None of them held still long enough to leave a trace.

In the bottom left corner of the frame, at the junction where a paved forecourt meets the tree line, a small dark mark resolves, under magnification, into two figures: a stationary shape and, beside it, a fainter, blurred one bent toward it. Every other person, cart and carriage on the boulevard that morning has vanished into the blank pavement and the smear of half-registered trees. The plate did not fail to record the crowd. It recorded exactly what an exposure of several minutes will show of a moving city: nothing, except whatever refused to move.

How the picture was made

The daguerreotype process that Daguerre had perfected by 1837 exposed a sheet of copper plated with silver and sensitized with iodine vapor, inside a camera obscura, then developed the latent image with mercury vapor and fixed it in a salt bath. The exposure required was long by any later standard, and the sources consulted for this record give figures ranging from four to five minutes up to more than ten, without agreement on which is correct for this specific plate.

The view looks down the boulevard from an upper floor, and the sources agree this was a window near Daguerre's own apartment beside the Diorama building he had built and operated on the rue des Marais, close to the Place du Chateau-d'Eau, an area that today sits near the Place de la Republique. Daguerre did not have to travel to make this picture. He made it by pointing a camera out of his own workplace.

One man, or two

The identity and even the number of human figures in the frame has been read differently by different observers, and this record treats that as a live disagreement rather than a settled fact. Writing in 1937, the photography historian Beaumont Newhall described a single figure: a pedestrian who had stopped to have his boots polished and held still through most of the exposure.

Later commentary complicates this. The critic David Bate, quoted in a 2024 Cambridge University Press essay collection, argues there are two figures, not one: the customer having his boots cleaned, and a second, much fainter figure beside him, the bootblack doing the cleaning, visible only as a blur because he was in continuous motion at his work. Bate reads the pairing as significant in its own right, an exchange of paid labor and, on his account, of class difference, standing at the literal origin point of photography's ability to fix a human being at all.

Neither figure has ever been identified by name in any source consulted for this record. Popular accounts online frequently assert additional details, a child at a window, a horse, a second man reading a newspaper on a bench, with no citation this record could trace to a primary description of the plate. Those claims are omitted here rather than repeated. What can be said is narrower: at one inch from the bottom left corner of the plate, two shapes are visible that were not moving, or not moving fast, during an exposure that erased everything else.

Two views, and a still life, on the same day

The plate usually reproduced as 'Boulevard du Temple' is not the only surviving image from this session. Daguerre made a second exposure of the same view at midday, from the same window, showing the same buildings and street furniture and no visible figures at all. The two plates are consistently described in the literature as companions made the same day, the morning exposure carrying the figures and the noon exposure serving, in effect, as the control that shows what an empty street actually looks like when nothing distinguishes it.

Daguerre mounted this pair with a third image, a studio still life of plaster casts arranged on a draped table, into a three part presentation set. The still life is not a street scene and was evidently included to demonstrate the process on a different kind of subject: a static, controllable arrangement rather than a public thoroughfare exposed to whatever passed through it. Together the three plates read as a demonstration piece built to show a single audience, in one framed object, what the new process could do with architecture, with atmosphere, and with a subject that never moved at all.

A gift for a king

The three plate set was presented to Ludwig I, King of Bavaria, and according to a Cambridge University Press essay collection was on display at the Kunstverein, the arts association in Munich, from 20 October 1839, two months after Daguerre's process had been publicly announced in Paris. Giving a demonstration set to a reigning monarch, months after making the invention public, reads as a documented strategy rather than a private courtesy: a sitting king's patronage was a fast route to prestige and credibility for an inventor whose process had just been declared free to the world, and Daguerre is known to have pursued comparable recognition and honors from other governments in the same period. The plate's audience, in other words, was chosen for reasons that had nothing to do with the boulevard itself.

The set with the dedication remained in the Bavarian royal collection for close to thirty years before it reached the institution that holds it now. The Bayerisches Nationalmuseum's own online collection record gives the transfer into the museum's holdings as 1868, using the German term 'Ueberlassung', meaning a cession or handover rather than a purchase. The museum's record does not specify the legal mechanism, whether this was a transfer from the royal household to state property, an internal reallocation, or something else, and no other source consulted supplies that detail. What is documented is the date and the fact of a transfer, not its administrative machinery.

A fire that this plate escaped

On 8 March 1839, five months before the daguerreotype process was made public and roughly seven months before the presentation set went on display in Munich, a fire destroyed Daguerre's Diorama building in Paris. English Wikipedia's account, drawing on the standard biographical literature, states that the fire consumed daguerreotype specimens, notebooks and equipment stored on an upper floor of the building. This record has not traced an itemized inventory of what was lost, but the general point is not disputed: a working inventor's early experimental output was concentrated in one building, and that building burned down within a year of this plate's exposure.

The Boulevard du Temple plate survived because it was not in the building when the fire happened, either because it had already been set aside as a presentation piece or because it was elsewhere in Daguerre's possession. Either way, its survival should be read against the backdrop of a documented loss event that plausibly destroyed a great many comparable early plates that will never be catalogued because no description of them survives. Scarcity here is not simply a function of age. It is partly a function of what burned.

What happened to the original plate

Every source consulted agrees that the original plate or plates presented to Ludwig I were damaged by a later cleaning or restoration attempt. No two sources consulted agree on when.

French Wikipedia's article states the plate was clumsily cleaned in 1960. Several English language accounts, none traced to a primary conservation record, place a damaging restoration in 1970, after the set was lent to the Munich Stadtmuseum. A 2024 Cambridge University Press essay collection states flatly that the original was destroyed during cleaning at the 'Munich Fotomuseum' around 1974, and that only an empty wooden frame with a descriptive label now survives as physical evidence of the original object. Other popular accounts describe an overzealous cleaning attempt shortly after the Second World War, distinct from all three of the dates above.

This record does not resolve the contradiction, because none of the sources consulted resolve it either, and inventing a single account by picking the most repeated version would misrepresent a genuine, documented disagreement as a settled fact. What can be said without qualification is narrower: the plate that toured as a symbol of photography's earliest years in the twentieth century was, by every account, already a copy of something that had been damaged, and by at least one serious academic account, of something that no longer physically exists in its original form at all.

How the world still has the image

The image survived its own object's damage because it had already been copied. In 1936 or 1937, the American photography historian Beaumont Newhall photographed the plate for an exhibition and publication project, producing a high quality negative before the reported cleaning damage occurred. Multiple sources agree that the daguerreotype facsimiles later produced for display, and by extension most photographic reproductions of this image in circulation since, trace back to Newhall's copy negative rather than to any fresh photograph of the plate as it exists today.

This has a direct consequence for how any reader should treat an image labelled 'Boulevard du Temple' found online or in a printed history of photography: it is very unlikely to be a photograph of the object as it currently exists, and is instead, at some number of generations of remove, a reproduction of a reproduction made before the damage occurred. The high resolution version most widely used online and credited to a 1997 Phaidon Press publication sits within that same chain rather than outside it. This record's lead image is drawn from that chain and is captioned accordingly rather than presented as a fresh photograph of the surviving plate.

Rival claims to the same title

The claim made for this plate is specific and narrower than it is usually stated: not the first photograph, and not even reliably the first photograph with a human trace in it, but among the earliest surviving photographs in which a person can be seen at all, and the earliest to show one incidentally, as a by-product of photographing a place rather than as the deliberate subject of the picture.

The earliest surviving photograph of any kind was made over a decade earlier by Nicephore Niepce, Daguerre's own former partner, using a different process entirely. Niepce's 'View from the Window at Le Gras', made around 1826 or 1827 by exposing a pewter plate coated with bitumen of Judea, shows a rooftop view with no person visible, and is held at the Harry Ransom Center at the University of Texas at Austin. It predates Daguerre's street view by a decade and holds a distinct and better documented claim: earliest surviving photograph outright.

A different, later claim belongs to Robert Cornelius, an amateur chemist in Philadelphia, who made a self-portrait in his family's yard in October or November 1839, months after Daguerre's process was published and roughly a year and a half after the Boulevard du Temple exposure. Cornelius's picture is usually credited as the earliest surviving deliberate photographic portrait, a meaningfully different claim from an incidental figure caught in a street view: Cornelius chose to be photographed and arranged the picture himself, where the man or men on the Boulevard du Temple did not know a camera was pointed at them and were recorded only because a shoeshine took long enough to outlast the exposure.

French Wikipedia's bibliography also references a study, credited to Andre Gunthert and Jacques Roquencourt, examining an alternative dating of 1837 for a different early daguerreotype sometimes called a portrait of a Monsieur Huet. This record has not read that study directly, and notes only that French Wikipedia describes the 1837 dating attached to that separate image as too uncertain to stand, which is itself the correct way to treat a claim of this kind: it is mentioned to show that this field is full of competing early claims, most of which do not hold up, rather than to assert anything about the Huet image's actual content.

What later readers have made of it

Daguerre's own stated purpose for the plate, so far as it can be recovered, was promotional and technical: a demonstration piece built to secure the reputation and patronage that followed a working inventor around Europe in 1839. Whatever meaning the picture has since acquired was added afterward, by readers looking at a street photograph made for an entirely practical reason.

The strongest example is Bate's reading of the two figures as an unintentional record of a labor transaction, a customer and a tradesman, arguably the first record of a specifically economic human relationship that photography ever produced, whether or not anyone at the time saw it that way. This is a documented interpretation attributed to a named critic, not a claim about what Daguerre intended, and this record treats it as exactly that: a later reading, not an original program. No source consulted attributes any symbolic, religious or esoteric intention to this image at the time it was made, and none should be invented. Its content is a street, a demonstration, and a king who was worth impressing.

Technical evidence

Boulevard du Temple
ProcessDaguerreotype: an iodized, silver-plated copper sheet exposed in a camera obscura, developed in mercury vapor, and fixed in a salt (later sodium thiosulfate) solution.5
SupportSilver-plated copper sheet.34
DimensionsApproximately 13 x 16 cm, per secondary literature. Not confirmed against a primary museum specification sheet in the sources consulted.4
ExposureReported variously as four to five minutes, several minutes, or over ten minutes, depending on the source. No primary conservation or optical study settling the figure was found in the sources consulted.234
OrientationThe image as commonly reproduced is understood to be a mirror reversal of the real scene, as produced directly by the camera obscura process without a correcting mirror. A separate, laterally flipped 'unmirrored' reproduction also circulates on Wikimedia Commons.7
Accession and classificationHeld by the Bayerisches Nationalmuseum under inventory R 6312.1-8, catalogued by the museum itself as 'Daguerreotypien (Originale) und Daguerreotypien (Faksimiles)'. The accession record spans both original plate material and later facsimiles rather than describing a single unambiguous object.1
Present conditionThe plate or plates originally presented to Ludwig I are reported by every source consulted to have been damaged by a later, undated cleaning or restoration attempt, and by one academic source to have been destroyed outright (see Open Questions). What the museum's own database describes at this inventory number today is a set of facsimiles in the original 1839 passepartout and frame.12

Provenance

  • 1838 - 1839
    Louis Jacques Mande Daguerredocumented

    Exposed from a window near Daguerre's own apartment beside his Diorama building on the rue des Marais, Paris, in 1838 (the precise date within the year is itself disputed; see Open Questions). Daguerre retained the plate, along with a companion midday view and a studio still life, as a presentation set.45

  • 1839 - 1868
    Ludwig I, King of Bavariadocumented

    Daguerre presented the three plate set, with a dedication inscription in his own name, to Ludwig I of Bavaria. A Cambridge University Press essay collection gives 20 October 1839 as the date the set went on display at the Kunstverein in Munich. The set remained in the Bavarian royal collection for close to three decades.12

  • 1868 - present
    Bayerisches Nationalmuseum, Munichdocumented

    The museum's own online collection database records the accession as a transfer ('Ueberlassung') in 1868, under inventory R 6312.1-8. The legal mechanism of the transfer from royal to museum holdings is not specified in the source consulted.1

  • Unresolved: the fate of the original plate materialdisputed

    Every source consulted agrees the original plate or plates were damaged by a later cleaning or restoration attempt, but the sources disagree by more than a decade on when: shortly after the Second World War, in 1960, in 1970 (on loan to the Munich Stadtmuseum), or in 1974 (at the 'Munich Fotomuseum', per one academic source, which states the original was destroyed and only an empty frame survives). This record grades the event as disputed rather than adopting any single account.234

  • 1936 - 1937
    Beaumont Newhall (copy negative, not ownership of the plate)documented

    Newhall photographed the plate for an exhibition and publication project, producing a copy negative before the reported damage occurred. Facsimiles subsequently produced for display, and most photographic reproductions of the image in general circulation, are understood to derive from this copy rather than from a fresh photograph of the plate as it exists today.23

Open questions

  • What is the precise date of exposure? Most literature places it on a morning between 24 April and 4 May 1838, inferred from shadow length and foliage, but some sources give 1837 instead, and the sources consulted do not resolve the disagreement.
  • Are there one or two human figures in the frame? Beaumont Newhall's 1937 account described a single stationary man having his boots polished; a later reading credited to David Bate identifies a second, blurred figure, the bootblack at work. Neither figure has ever been identified by name in any source consulted.
  • Does the original plate presented to Ludwig I still physically exist? Every source agrees it was damaged by a later cleaning or restoration attempt, but the sources disagree on the date by more than a decade (accounts place it variously shortly after the Second World War, in 1960, in 1970, and in 1974), and one academic source states the original was destroyed outright, leaving only an empty frame. No conservation report resolving this was found.
  • What, precisely, does the Bayerisches Nationalmuseum hold today under inventory R 6312.1-8, and is any of it ever exhibited? The museum's own database describes the item as facsimiles in the original passepartout and frame, without stating where, or whether, any surviving original plate material is separately stored.
  • By what legal mechanism did the 1839 royal gift become Bayerisches Nationalmuseum property in 1868? The museum's record supplies only the German term for a transfer or cession and the year, with no further detail in the sources consulted.
