He is regarded as the father of modern scientific bibliography, zoology and botany. He was frequently the first to describe species of plants or animals in Europe, such as the tulip in 1559. A number of plants and animals have been named after him.


Life

Conrad Gessner was born on 26 March 1516, in Zürich, Switzerland, the son of Ursus Gessner, a poor Zürich furrier. His early life was one of poverty and hardship, but Gessner's father realized his talents, and sent him to live with and be schooled by a great uncle, who grew and collected medicinal herbs for a living. Here the boy became familiar with many plants and their medicinal purposes which led to a lifelong interest in natural history. Gessner first attended the ''Carolinum'' in Zürich, then later entered the Fraumünster seminary. There he studied classical languages, appearing as Penia (Poverty) in

In school, he impressed his teachers so much that a few of them helped sponsor him so that he could further his education, including arranging a scholarship for him to attend university in France to study theology (1532–1533) at the age of 17. There he attended the University of Bourges and

, but being unable to secure employment, he returned to Zürich. One of his teachers in Zürich acted as a foster father to him after the death of his father at the Battle of Kappel (1531), another provided him with three years of board and lodging, while yet another arranged his further education at the upper school in Strasbourg, the Strasbourg Academy. There he broadened his knowledge of ancient languages by studying Hebrew. In 1535, religious unrest drove him back to Zürich, where he made what some considered an imprudent marriage at the age of 19, of a woman from another poor family who had no

(1536). Throughout his life Gessner was interested in natural history, and collected specimens and descriptions of wildlife through travel and extensive correspondence with other friends and scholars. In 1543 Arnoldus Arlenius invited Gessner to Venice. Gessner travelled to Italy that same summer. He encountered Venetian printing and a hidden world of Greek manuscripts.Sabba,F. La ‘Bibliotheca Universalis’ di Conrad Gesner: monumento della cultura europea. Conrad Gessner, 127–136. (Rome, 2012), Conrad Gessner, 127–136. Gessner's approach to research consisted of four main components: observation, dissection, travel to distant lands, and accurate description. This rising observational approach was new to Renaissance scholars because people usually relied completely upon Classical writers for their research. He died of the plague, the year after his ennoblement on 13 December 1565.

). Here he had leisure to devote himself to scientific studies, especially botany, and earn money to further his medical studies. After three years of teaching at Lausanne, Gessner was able to travel to the medical school at the University of Montpellier, where he received his doctoral degree (1541) from Basel. He then returned to Zürich to practice medicine, which he continued to do for the rest of his life. There he was also appointed to the post of lecturer of Aristotelean physics at the ''Carolinum'', the precursor of the University of Zürich. After 1554 he became the

(). In addition to his duties there, and apart from a few journeys to foreign countries, and annual summer botanical journeys in his native land, and illnesses, he was able to devote himself to research and writing. His expeditions frequently involved visits to mountainous country, below the snow-line. Although primarily for purposes of botanical collection, he also extolled mountain climbing for the sake of exercise and enjoyment of the beauties of nature. In 1541 he prefixed to his treatise on milk and milk products, ''Libellus de lacte et operibus lactariis'' a letter addressed to his friend Jacob Avienus (Vogel) of

Publications

Gessner's first work was a Latin-Greek Dictionary, the ''Lexicon Graeco-Latinum'' (1537), compiled during his studies in Basel. This was a revision of an original work by the Italian cleric, Varinus Phavorinus or Guarino of Favera (d. 1537), ''Magnum ac perutile dictionarium'' (1523). Over his lifetime he was able to produce some 70 publications on many different subjects. His next major work was his unique '' Bibliotheca'' (1545), a landmark in the history of bibliography, in which he set out to catalogue all the writers who had ever lived and their works. In addition to his monumental work on animal life, the (1551–1558), he amassed a very large collection of notes and wood engravings of plants, but only published two botanical works in his lifetime, ''Historia plantarum et vires'' (1541) and the ''Catalogus plantarum'' (1542) in four languages. It was in the last decade of his life that he began to compile his major botanical work, '' Historia plantarum''. Although he died prior to its completion, his work was utilised by many other authors over the next two centuries, but was finally published in 1754. Not content with scientific works, Gessner was also active as a

), some long after (''see Posthumous works''). His work on insects was edited by various authors, including Thomas Penny, until Thomas Muffet brought it to publication as ''Insectorum sive minimorum animalium theatrum'' (1634), finally appearing in English translation as ''The Theatre of Insects'' in Edward Topsell's ''History of Four-Footed Beasts and Serpents'' (1658).


''Bibliotheca universalis'' (1545–1549)

In 1545, after four years of research, Gessner published his remarkable '' Bibliotheca universalis'', an exhaustive catalogue of all known works in Latin, Greek and Hebrew, of all writers who had ever lived, with the titles of their works, and brief annotations. The work, which included his own bio-bibliography, listed some three thousand authors alphabetically, and was the first modern bibliography published since the invention of printing. Through it, Gessner became known as the "father of bibliography." In all, about twelve thousand titles were included. A second part, a thematic index to the work, ''Pandectarum sive partitionum universalium libri xxi'', appeared in 1548. Although the title indicated that twenty one parts were intended, only nineteen books were included. Part 20, intended to include his medical work, was never finished and part 21, a theological encyclopaedia, was published separately in 1549.

s, amphibians, birds, and fishes. A fifth folio on snakes was issued in 1587. A German translation of the first 4 volumes titled ''Thierbůch'' was published in Zürich in 1563. This book was considered to be the first modern zoological work. It built a bridge between ancient, medieval and modern science. In Gessner combines data from old sources, such as the Old Testament, Aristotle, Pliny, folklore, and medieval bestiaries, adding his own observations. He created a new, comprehensive description of the Animal Kingdom. This was the first attempt by anyone to describe many animals accurately. The book unlike many works of its time was illustrated with hand-colored woodcuts drawn from personal observations by Gessner and his colleagues. Even though he sought to distinguish observed facts from myths and popular errors and was known for his accurate depiction of many animals in , he also included many fictional animals such as the Unicorn and the Basilisk, which he had only heard about from medieval bestiaries. But when Gessner doubted the accuracy of the opinions he relayed in his own writings, or the validity of the illustrations he included, he clearly said so. Besides any plant or animal's potential advantage to people, Gessner was interested in learning about them because of the moral lessons they could teach and the divine truths they might tell. He went into as much detail about some unreal animals as he did about real ones. Later in 1556 he also combined real and fictional creatures in his edition of the works of

. Not only did they send him their ideas, but also sent him plants, animals and gems. He returned the favor – and kept helpful specimens coming – by naming plants after correspondents and friends.


''Historia plantarum'' (unfinished)

Over his lifetime, Gessner amassed a considerable collection of plants and seeds and made extensive notes and wood engravings. In the last decade of his life he began to compile his major botanical work, ''Historia plantarum''. although he died prior to its publication his materials were utilised by many subsequent authors for the next two hundred years. These included some 1,500 engravings of plants and their important flowers and seeds, most of which were original. The scale and scientific rigour of these were unusual for the time, and Gessner was a skilled artist, producing detailed drawings of specific plant parts that illustrated their characteristics, with extensive marginal notation discussing their growth form and habitation. Finally, the work was published in 1754.


Censorship

There was extreme religious tension at the time that came out. Under
Pope Paul IV Pope Paul IV (; ; 28 June 1476 – 18 August 1559), born Gian Pietro Carafa, was head of the Catholic Church and ruler of the Papal States from 23 May 1555 to his death, in August 1559. While serving as papal nuncio in Spain, he developed ...
the Pauline Index felt that the religious convictions of an author contaminated all his writings. Since Gessner was a Protestant his works were included in this index of prohibited books. Even though religious tensions were high, Gessner maintained friendships on both sides of the Catholic-Protestant divide. In fact, Catholic booksellers in Venice protested the Inquisition's blanket ban on Gessner's books, and some of his work was eventually allowed after it had been "cleaned" of its doctrinal errors.

Legacy

Gessner has been described as the father of modern scientific botany and zoology, and the father of modern bibliography. To his contemporaries he was best known as a botanist. Despite his traveling ways and the job of maintaining his own gardens, Gesner probably spent most of his time inside his own extensive library. He listed among his History of Animals sources more than 80 Greek authors and at least 175 Latin authors, as well as works by German, French, and Italian authors. He even attempted to establish a "universal library" of all books in existence. The project might sound strange to the modern mind, but Gessner invested tremendous energy in the project. He sniffed through remote libraries along with the collections of the Vatican Library and catalogs of printers and booksellers. By assembling this universal library of information, Gessner put together a database centuries before computers would ease such work. He cut relevant passages out of books, grouped the cuttings by general theme, subdivided the groups into more specific categories, and boxed them. He could then retrieve and arrange the cuttings as needed. In the words of science writer Anna Pavord, "He was a one-man search engine, a 16th-century Google with the added bonus of critical evaluation." To his contemporaries, Gessner was known as "the Swiss Pliny." According to legend, when he knew his time was near, he asked to be taken to his library where he had spent so much of his life, to die among his favorite books. At the time of his death, Gesner had published 72 books, and written 18 more unpublished manuscripts. His work on plants was not published until centuries after his death. In 1576 George Baker published a translation of the ''Evonymus'' of Conrad Gessner under the title of ''The Newe Jewell of Health, wherein is contained the most excellent Secretes of Physicke and Philosophie divided into fower bookes''. Amongst his students was Felix Plater, who became a professor of medicine, and accumulated many plant specimens, but also illustrations of animals used in ''Historiae animalium''. A year after his death, his friend Josias Simler published a biography of Gessner. Gessner and others founded the ''Physikalische Gesellschaft'' in Zurich, which later became the '' Naturforschende Gesellschaft in Zürich'' (NGZH) in 1746, to promote the study of natural sciences. Today it is one of the oldest Swiss scientific societies. The society's annual publication, the ''Neujahrsblatt der Naturforschenden Gesellschaft in Zürich'' was devoted to a biography of Gessner in 1966, to celebrate the 400th anniversary of his death.
