Every 8 September, the world marks International Literacy Day to remind us that literacy is not merely a technical skill, but a fundamental human right and the cornerstone of civilisation. However, did you know that the global literacy revolution we enjoy today traces its origins back to a dusty workshop in Mainz, Germany, in the mid-15th century? 

During the Middle Ages, it was almost impossible for ordinary people to own a Bible or other books. Monks had to copy texts by hand onto sheets of papyrus or animal skin. The cost of materials and the extremely long time required for copying made books prohibitively expensive—it is said that the price of a single book at that time was comparable to that of a plot of land or a house.

This problem was exacerbated by the fact that very few people could read in their own language. Books, including the Bible, were available only in Latin—a language understood only by a handful of educated people. Knowledge, too, became a luxury, locked away in palaces, places of worship, or the private libraries of the nobility. Ordinary people lived in a state of illiteracy, relying on oral traditions and dogma without ever having the opportunity to interpret the world through their own eyes. Access to ideas and concepts was a privilege, not a fundamental right. 

It was against this backdrop that a man named Johann Gutenberg emerged. He staked everything—his finances, his reputation, and even his future—to create a movable-type printing press. Gutenberg’s endeavour not only transformed the way books were produced, but also brought down the thick walls that had for centuries separated the general public from knowledge.

Born in Mainz, Raised in Strasbourg

Gutenberg was born Henne Gänsfleisch zur Aden sometime in the 1400s. He was the son of Friele (Friedrich) Gänsfleisch and Else Wyrich, a respected couple of noble descent in the city of Mainz. The family had inherited the coin-minting business through the generations. It was this family background that equipped Gutenberg with a deep understanding and expertise in metalworking—a skill that would later prove to be the key to his great invention.

 
In his youth, political unrest forced Gutenberg to leave Mainz and move to Strasbourg. He is recorded as having settled in that city from 14 March 1434. Although he lived amongst the nobility, Gutenberg also maintained close ties with the local goldsmiths’ guild. Thanks to his technical expertise and reliable business acumen, he taught various skills to his pupils and colleagues—such as Andreas Dritzehn, Hans Riffe, and Andreas Heilmann. The skills he taught ranged from the art of gem polishing and mirror production to printing techniques. According to historical records, Gutenberg’s expertise as a goldsmith enabled him to successfully supply printing materials worth 100 gulden.

 
In 1437, Gutenberg faced a legal demand to marry a noblewoman from Strasbourg named Ennel zur eisernen Tür. However, there are no definitive records to confirm whether the marriage actually took place. Gutenberg appeared instead to be more focused on devoting his funds and attention to developing his inventive projects, as evidenced by his printed works *Weltgerichtsgedicht* (which contains the *Poem of the Last Judgement*) and the *Calendar for the Year 1448*.

 
Designing the Movable Type Printing Press

In 1450, Gutenberg entered into a financial partnership with a wealthy man from Mainz named Johann Fust. This partnership was formed to acquire the equipment for the printing press he had designed, with a view to printing the major project he called the ‘42-Line Bible’. Between 1453 and 1455, Gutenberg successfully completed his printing press project.

However, in 1455, a major storm struck his business endeavours. Johann Fust filed a lawsuit to reclaim his investment of 2,000 gulden, plus interest. The court ruled in Fust’s favour, resulting in half of Gutenberg’s invention and printing equipment falling into the hands of his business partner.

 
This bankruptcy did not deter Gutenberg. Using his remaining personal funds, in 1457 he continued to develop his invention with the ‘32-line Bible’ typeface. Long before that Bible was printed, he had in fact already used this type of typeface in one edition of the *Weltgerichtsgedicht*, the Donatus edition of the 1448 Calendar, as well as in other printed works that later came into the possession of Albrecht Pfister in Bamberg. 

Refusing to give up, Gutenberg subsequently established a new printing company with the assistance of Dr Conrad Humery, a doctor of law who was also a leading figure in a major political party and a councillor. This new company utilised a new set of metal typefaces designed to replace the rounded cursive handwriting style commonly used at the time. This new typeface was subsequently used to print a grammar book and lexical alphabet entitled *Catholicon* in 1460, as well as several small books printed in Eltville in 1472 by Echtermünze, who was still related to Gutenberg. 

In his later years, Gutenberg spent the remainder of his life under the patronage of Archbishop Adolf von Nassau from 1465 onwards. The honours and allowances he received ensured that his needs were well provided for. It was in these peaceful circumstances that Gutenberg passed away towards the end of 1467 or early 1468. He was buried in the Franciscan Church in Mainz, although the exact location of his grave has since been lost to the passage of time. 

The Flame that Changed Civilisation

Gutenberg’s invention was not merely about the efficiency of a machine, but about the massive opening of the gates of knowledge to all of humanity. By 1483—the year Martin Luther was born—almost every country in Europe possessed at least one printing press. Within just 50 years of Gutenberg printing the first Bible, printing presses across Europe had produced a number of books far exceeding the total number of hand-copied works produced by monks over the preceding centuries. 

Books began to appear in various local languages, and literacy rates soared dramatically. From that single, simple press in Mainz, thousands of pages of ideas could be reproduced in a matter of days. Knowledge, science, philosophy and literature were no longer confined to closed rooms; they flourished across the boundaries of cities, nations and even social classes. 

Several decades later, Martin Luther, the reformer of the Church, described Gutenberg’s invention of the printing press as one of God’s greatest blessings. Luther declared: “Printing is the highest and greatest grace of God, by which the message of the Gospel is propelled forward.” Through Gutenberg’s printing press, Luther and the reformers were able to convey the word of God via the printed word with such speed that it reached ‘every ploughboy and maidservant’. 

Gutenberg’s printing revolution acted like a spark in the midst of a dry grassland. People learnt to read, and through that ability to read, they learnt to think critically, to question injustice, and to weave together aspirations for freedom. The printing press has torn down the walls of information inequality and forever altered the course of human civilisation. From Germany to the far corners of Europe, the Gospel was spread to every corner of the world—bringing millions, even billions, of people into encounter with Christ and enabling them to discover a new life filled with peace and prosperity.
