1721 - ca 1862.
The Amsterdam publishing firm of Covens and Mortier (1721 - c. 1862) was the successor to the extensive publishing empire built by Frenchman Pierre Mortier (1661 - 1711). Upon Mortier's death in 1711 his firm was taken over by his son, Cornelius Mortier (1699 - 1783). Cornelius married the sister of Johannes Covens (1697 - 1774) in 1821 and, partnering with his brother in law, established the Covens and Mortier firm. Under the Covens and Mortier imprint, Cornelius and Pierre republished the works of the great 17th and early 18th century Dutch and French cartographers De L'Isle, Allard, Jansson, De Wit, and Ottens among others. They quickly became one of the largest and most prolific Dutch publishing concerns of the 18th century. The firm and its successors published thousands of maps over a 120 year period from 1721 to the mid-1800s. During their long lifespan the Covens and Mortier firm published as Covens and Mortier (1721-1778), J. Covens and Son (1778 - 94) and Mortier, Covens and Son (1794 - c. 1862)

Frisius, Gemma. [Reinerszoon, Jemme.]
9 december 1508 - 25 maj 1555.
Gemma Frisius was a physician, mathematician, cartographer, philosopher, and instrument maker. He created important globes, improved the mathematical instruments of his day and applied mathematics in new ways to surveying and navigation.
Frisius was born in Dokkum, Friesland (present-day Netherlands) of poor parents, who died when he was young. He moved to Groningen and studied at the University in Leuven beginning in 1525. He received the degree of MD in 1536 and remained on the faculty of medicine in Leuven for the rest of his life. His oldest son, Cornelius Gemma, edited a posthumous volume of his work and continued to work with Ptolemaic astrological models.
While still a student, Frisius set up a workshop to produce globes and mathematical instruments. He became noted for the quality and accuracy of his instruments, which were praised by Tycho Brahe, among others. In 1533, he described for the first time the method of triangulation still used today in surveying. Twenty years later, he was the first...

Död ca. 1568. Född i Piemonte.
Italiensk kartograf. Om hans liv finns inga säkra upplysningar förrän han 1544 dyker upp i Venedig som en fullt erfaren kartograf. Hans första kända arbete är en specialkarta över Spanien och Sicilien. 1548 gav han ut en Ptolemaeus-geografi med 60 kartor, varav 34 efter hans egna teckningar. Dessa kartor användes senare i flera andra utgåvor. Började i republiken Venedigs tjänst som kosmograf. 1550 dekorerade han stadshusets stora sal med en gigantisk Afrika-karta målad direkt på väggen. I övrigt utförde han under dessa år flera stora kartarbeten, både hela världskartor och specialkartor över mindre områden, i synnerhet Italien, södra Europa och övriga Medelhavsländer. Blev berömd och 1558 vald till professor i geografi vid 'Accademia della Fama'. Åt Venedig utförde han också olika målnings- och ingenjörsarbeten.

Keere, Pieter van den [Kaerius, Petrus]
Biografiska uppgifter:1571-c. 1646.
Pieter van den Keere was one of a number of refugees who fled from religious persecution in the Low Countries between the years 1570 and 1 590. He moved to London in 1584 with his sister who married Jodocus Hondius, also a refugee there, and through Hondius he undoubtedly learned his skills as an engraver and cartographer. In the course of a long working life he engraved a large number of individual maps for prominent cartographers of the day but he also produced an Atlas of the Netherlands (1617-22) and county maps of the British Isles which have become known as Miniature Speeds, a misnomer which calls for some explanation.
In about 1599 he engraved plates for 44 maps of the English and Welsh counties, the regions of Scotland and the Irish provinces. The English maps were based on Saxton, the Scottish on Ortelius and the Irish on the famous map by Boazio. These maps were not published at once in book form but there is evidence which suggests a date of issue (in Amsterdam) between 1605 and 1610 although at least one authority believes they existed only in proof form until 1617 when Willem Blaeu issued them with a Latin edition of Camden's Britannia. At this stage two maps were added, one of the British Isles and the other of Yorkshire, the latter derived from Saxton. To confuse things further the title page of this edition is signed 'Guilielmus noster Janssonius', which is the Latinized form of Blaeu's name commonly used up to 1619.
At some time after this the plates came into the possession of Speed's publishers, George Humble, who in 1627, the year in which he published a major edition of Speed's Atlas, also issued the Keere maps as a pocket edition. For these he used the descriptive texts of the larger Speed maps and thereafter they were known as Miniature Speeds. In fact, of the 63 maps in the Atlas, 40 were from the original van den Keere plates, reworked, 16 were reduced from Speed and 7 were additional. The publication was very popular and there were further re-issues up to 1676.
