MUNDANEUM

Monde est tout notre objet,

Universelle notre tendance,

Nous voulons : croire au progrès, à l'intelligence,

Désarmer les bras, les cœurs, les mentalités,

À travers tout l'espace, à travers tous les temps.

Nation, homme, société, la divinité

Est à l'ouest, nord aux extrémités,

Unir, organiser, par excellence

Monde, qui est bien notre objet.

Making the world our whole objective,

Universal is our tendency,

Now we want: to believe in progress, in intelligence,

Disarm arms, hearts, and mindsets,

Across all space, across all time.

Nation, man, society, divinity

Extending west, north to the extremities,

Unite, organize, par excellence

Making the world truly our objective.

The Origins of the Internet and the Quest for Knowledge

Attributing the creation of the internet to a single individual is complex, as numerous key figures contributed throughout modern computing history:

• Leonard Kleinrock led the team at UCLA and Stanford that built the earliest computer network and transmitted the first online message in 1969.

• Sir Tim Berners-Lee invented the World Wide Web and created the world's very first website in 1990.

• Vint Cerf and Bob Kahn, widely acknowledged as the fathers of the internet, developed TCP/IP in 1973—the foundational set of networking protocols allowing interconnected computers to communicate.

• Larry Roberts connected two computers for the first time in 1965.

• Donald Davies invented packet switching in 1965, enabling efficient digital communications.

• Abhay Bhushan created the File Transfer Protocol (FTP) in 1971.

• Bob Metcalfe, alongside David Boggs, co-invented Ethernet networking technology in 1980.

While these engineers built the technological backbone of the digital age, internet pioneer Vint Cerf noted that the core conceptual idea of a globally accessible information network was actually born in Belgium.

The Mundaneum: A 100-Year-Old Information Engine

In the early 20th century, two Belgian visionaries envisioned a centralized index to compile, cross-reference, and preserve the entirety of human knowledge:

• Paul Otlet: A Belgian lawyer, author, and documentation scientist.

• Henri La Fontaine: Otlet's close collaborator, a legal scholar and politician who won the Nobel Peace Prize in 1913.

Together, they founded an ambitious collaborative endeavor known as The Mundaneum (also documented with its symbolic Latin emblem deciphered as "Monde est tout notre objet, universelle notre tendance"). Their goal was to construct what was effectively a paper-based predecessor to Wikipedia.

Because electronic computers and network servers did not exist in 1910, Otlet and La Fontaine built a physical database consisting of 12 million index cards housed within massive wooden catalog drawers. Each card contained meticulously organized entries on distinct subjects contributed by experts across the globe.

Expansion at the Palais du Cinquantenaire

To accommodate this burgeoning repository, the Belgian government granted Otlet and La Fontaine an entire wing of the Palais du Cinquantenaire in Brussels in 1914. Following World War I, the Mundaneum rapidly grew into an expansive center occupying over 100 rooms. Beyond index cards, it housed vast collections of books, newspapers, journals, posters, and multimedia items.

To organize this colossal library, Otlet and La Fontaine created the Universal Decimal Classification (UDC) system. Adapted from the Dewey Decimal System to be internationally adaptable, the UDC categorized knowledge into structured thematic branches—including history, geography, science, mathematics, and specialized adult literature—and remains widely used by librarians worldwide today.

When opened to the public in 1920, the Mundaneum attracted broad crowds of everyday citizens eager to explore its vast collection, operating as a functional open-access information hub.

Prophetic Vision of Modern Technology

Despite early success, the project faced administrative opposition. In 1924, the Belgian government cleared out half of the Mundaneum’s rooms in the Palais du Cinquantenaire to hold a commercial trade fair for the Belgian rubber industry ("Cinquième Foire Commerciale de Bruxelles").

Compelled to condense their archives into a smaller space, Otlet turned his attention toward conceptualizing electronic information storage. In his 1934 treatise, Le Livre sur le Livre ("The Book on the Book"), Otlet described a remarkably accurate vision of the modern workstation and cloud computing architecture:

He predicted that a worker's desk would no longer require physical books, featuring instead a visual display screen and a telephone. Remote central repositories housed in large dedicated facilities would hold all texts and data, distributing them to users across wired or wireless channels. Queries typed or spoken into the system would display retrieved pages on screen, complete with audio output from loudspeakers for media requiring sound.

In a single passage, Otlet foresaw modern technologies including server farms, the World Wide Web, online search engines, video streaming platforms, and wireless networks (Wi-Fi). While other authors had discussed similar concepts—such as Mark Twain's 1898 description of a futuristic communication device termed the "telelectroscope"—Otlet was among the first to outline a comprehensive, systematic architecture for a global web of information.

Closure, Destruction, and Historical Legacy

In 1934, the Belgian government withdrew funding and evicted the Mundaneum from the Palais du Cinquantenaire. The physical filing cabinets remained stored inside the building while the founders sought new premises.

Tragedy struck in 1941 during World War II when occupying Nazi forces invaded Brussels, seized the building, and destroyed a substantial portion of the index cards and archives to make space for an exhibition of Third Reich art.

Henri La Fontaine passed away in 1943, and Paul Otlet died a year later in 1944. Though their groundbreaking work faded into relative obscurity as modern electronic computing emerged in the decades that followed, their visionary principles remain fundamental to how information is organized on the modern internet.

Visiting the Mundaneum Museum Today

The surviving portions of the Mundaneum's grand filing system are preserved and exhibited at the Mundaneum Museum, housed within a converted former department store in central Mons, Belgium.
