Johann Heinrich Zedler (7 January 1706 in Breslau (now Wrocław, Poland) – 21 March 1751 in Leipzig) was a bookseller and publisher. His most important achievement was the creation of a German encyclopedia, the Grosses Universal-Lexicon (Great Universal Lexicon), the largest and most comprehensive German-language encyclopedia developed in the 18th century.

After training as a bookseller, Zedler founded his own publishing house in 1726. It was initially based in Freiberg, Upper Saxony, and in 1727 moved to the Publishing and Book Trade Center in Leipzig. His first major publication was an eleven volume edition of the writings of Martin Luther published between 1729 and 1734, with an index volume published in 1740. As the founding publisher of the Universal-Lexicon, started in 1731 and during his lifetime growing to a total of 64 volumes, Zedler got into a long-standing legal dispute with the established publishers in Leipzig, whose more specialized products were threatened.

Some time before the spring of 1737, Zedler suffered a financial collapse. His business was bought by the Leipzig businessman Johann Heinrich Wolf. Wolf provided funding for Zedler to continue with the Universal-Lexicon and other works he had already begun such as the General Chronicle of States, Wars, Churches and Scholarship (1733–1754, 22 volumes). Zedler also published new works such as the trade lexicon Allgemeine Schatz-Kammer Der Kaufmannschafft (1741–1743, 4 volumes and 1 supplement volume), stock exchange laws Corpus Juris Cambialis (Johann Gottlieb Siegels, 1742, 2 volumes) and the Historical-Political-Geographical Atlas of the Whole World (1744–1749, 13 volumes), published under the name of the Leipzig bookseller, Johann Samuel Heinsius the Elder.

Zedler died at the age of 45 in 1751, just a year after the conclusion of the alphabetic Universal-Lexicon. His name lives on with the colloquial name of the encyclopedia, which is known today as "the Zedler".

Early years

Johann Heinrich Zedler was born in 1706 in Breslau, the son of a shoemaker, and presumably did not have higher secondary education – if he attended school at all. He was an apprentice with the Breslau booksellers Brachvogel, then moved to the company of the Hamburg bookseller and publisher Theodor Christoph Felginer. In 1726 he moved to the Saxon town of Freiberg, and in September that year married Christiana Dorothea Richter (1695–1755), sister of publisher David Richter and daughter of a reputable merchant in the city, who was eleven years his elder. He used his wife's dowry to open a bookshop in Freiberg. Zedler only stayed in Freiberg for a short time since the mining town did not provide a sufficient market for books.

Independent bookseller and publisher in Leipzig

First major publishing project

In 1727, Zedler and his wife moved to the university and trade fair city of Leipzig. That year his name appeared in a list of sixteen publishing booksellers in Leipzig. In September, Zedler announced his first published works after moving to Leipzig. The ad appeared just before the Leipzig Michaelmas Fair in October and was aimed at the many visitors to the city for this event.

Early in 1728 Zedler published a notice of "A New Enlarged and Revised Edition of All the German Journals and Works of the Blessed Luther".Neue Zeitungen von gelehrten Sachen, Januar 1728, S. 60 und 63. Unlike the previous work by theologian Johann Gottlieb Pfeiffer, Zedler's book did not follow a chronological sequence, but organized the material around themes. This was the first of seven volumes of work designed for high school use. The work was financed through Praenumeration, a common practice at the time. Interested parties would pay for two sections in advance at the Easter Fair in 1728, with a discount, and then receive delivery at the following Michaelmas Fair in early October. Zedler offered a particularly attractive price, making reprint by other booksellers unprofitable.

Since Zedler could not expect to raise enough funds for publication in this way, he also took a loan of 2,665 thalers from his brother-in-law David Richter. It is clear that this was a time of considerable uncertainty. Although Zedler had committed to publication on October 1728, as a precaution the year 1729 was printed on the title page. However, he met the deadline and fourteen days before the fair announced that the book was ready and no new subscribers to the Praenumeration plan would be accepted.Neue Zeitungen von gelehrten Sachen, September 1728, S. 744. Within a year Zedler had built a viable publishing business based on the success of the Luther series.

Each volume in this series, as well as those of later published works, was dedicated by Zedler to high notables according to the practice of the time. The person named in the dedicatory preface and depicted with an engraved portrait often responded with a financial gift or an honorary title. The first such title was given to Zedler by Christian, Duke of Saxe-Weissenfels, to whom he dedicated the first and third volumes of Luther's writings. The Duke was an important supporter of the Protestant church and also a great hunting enthusiast. Zedler presented the first book to the Duke in person on his birthday.

Announcement of the Universal-Lexicon

On 26 March 1730 Zedler announced the seventh and eighth volumes of Luther's works in the journal New Learned Works, and also announced his next project: the Great Complete Universal Lexicon of Science and Art, with the first volume to be available through Praenumeration subscriptions.Neue Zeitungen von gelehrten Sachen, 26. März 1730, page 208.

Zedler intended to summarize many previously available reference works on various fields of knowledge into a single large work of reference. The plan was a challenge to the established publishers of Leipzig. For example, Johann Friedrich Gleditsch had published a household lexicon in 1704, and with its third edition of 1708 this had become a form of encyclopedia. Thomas Fritsch had published the General Historical Lexicon in 1709, the German-language equivalent of Le Grand Dictionnaire historique of Louis Moréri, a multi-volume project with contributions from specialist writers and scientists. In 1721, Johann Theodor Jablonski published a General Lexicon of Arts and Science. A series of small reference books and dictionaries for the public completed the range. All these works were now threatened by Zedler's project.

The first public reaction from an established Leipzig publisher came five weeks after Zedler's notice. Caspar Fritsch, son of Thomas Fritsch (who had died in 1726), was concerned about the effect on sales of the General Historical Lexicon, whose third edition was being prepared. He announced special pricing, and stressed the security of subscriptions to his established work.

Bid for copyright protection

On 13 September 1730 Zedler requested a Saxon printing privilege to protect the lexicon, which was advertised for the 1731 Easter Fair. These national privileges typically covered a period of five to ten years, and gave the original printer protection against foreign reprints during this time. The Leipzig Book Commission, which was responsible for granting such privileges, followed the normal process of posting an explanation of the print project and the privilege request for a week in all the bookstores of the city, during which period objections could be filed with the courts.

Both Caspar Fritsch and Johann Gottlieb Gleditsch, son of Johann Friedrich Gleditsch, raised objections. Fritsch argued that in 1724 his father had gained the Saxon privilege for the General Historical Lexicon with a ten-year term, and said that the Universal-Lexicon would not differ in content from this and other existing lexicons apart from paraphrasing. On 16 October 1730, the Upper Consistory in Dresden agreed with the arguments of Fritsch and Gleditsch, rejected Zedler's request, and warned that he would be subject to confiscation and a fine of 300 thalers if he reproduced any material from the General Historical Lexicon in his Universal-Lexicon. With this ruling, Zedler lost the first round in his dispute with the competing Leipzig publishers.

Continuation of the Leipzig "publishers war" Despite the decision of the Dresden court, Zedler continued with his project. On 19 October 1730 he informed the Leipzig journal New Learned Works that he was still accepting further Praenumeration subscriptions, and rejected all accusations of plagiarism. He said that the Universal-Lexicon was being written by learned and distinguished men who had no need to plagiarize, but could write the material from their own knowledge.

Zedler went on to say that he would not be deterred by envious enemies, but would bring out further important works. This referred to his latest publishing project, a General Chronicle of States, Wars, Religion and Scholarship. Zedler could rely on the support of Jacob August Franckenstein, a professor of natural and international law at the University of Leipzig, and was a friend of the publisher of New Learned Works, Johann Burckhardt Mencke. On 24 October 1730, Zedler sent the Council of the City of Leipzig a preprint of the proposed title page, but this time without the privilege claim.

Again, the local publishers protested, and the Leipzig Book Commission finally ordered Zedler to halt printing of the Universal-Lexicon and the Chronicle and to stop advertising these works. In addition, the court ordered Zedler to print and distribute its verdict or pay a penalty of 100 thalars. With the Universal-Lexicon in jeopardy, Zedler shifted production to neighboring Prussia. In Halle he was in contact with Johann Peter von Ludewig, a lawyer and the local University Chancellor. Ludewig was also senior staff member of the Council for the orphanage in Halle. Apparently he caused the orphanage to be assigned to Zedler for printing the Universal-Lexicon. Before this started, Zedler requested a royal Prussian printing privilege, and at the same time an Imperial privilege. He received the imperial privilege on 6 April 1731 from Charles VI, and the Prussian royal privilege only four days later.

Completion and seizure of the first volume of the encyclopedia Zedler could not meet the planned Easter 1731 delivery date for the first volume of the Lexicon. He therefore announced in an advertisement in New Learned Works on 15 April 1731 that the work would be ready for the Michaelmas Fair in October. He also announced that he was appointed and protected by the Prussian King and Elector of Brandenburg, Frederick William I.

Jacob August Franckenstein was editor of the first volume, and Johann Peter von Ludewig wrote the preface. It is only possible to guess at other authors who contributed to this and all subsequent volumes. Ulrich Johannes Schneider, an expert on Zedler and director of the Leipzig University Library, says that anonymity – at least at this early stage of the enterprise – was a deliberate strategy. Zedler kept the names of his employees secret to protect against lawsuits on theft of intellectual property. In his preface to the first volume of the lexicon, von Ludewig said that the Lexicon was entirely the work of Zedler's "nine muses", and that their names would be disclosed when the work was complete. This promise was not subsequently observed, and Schneider considers it highly questionable that there were nine authors. In any case, Schneider says that the appearance of the first volume was the start of "Europe's largest Encyclopedia project of the 18th Century".

Compromise, libel, renewed printing ban and exit of Franckenstein

The local Leipzig publishers were quick to react. During the Michaelmas Fair 1731 the Leipzig Book Commission ordered the seizure of all previously printed and undelivered copies. Zedler protested against the seizure, but the Commission maintained its verdict.
