Född 6 oktober 1654 i Strängnäs, död 24 mars 1720 i Stockholm.
Fram till adlandet 1693 Peringer, fornforskare. Yngre bror till orientalisten Gustaf Peringer, adlad Lillieblad.
Johan Peringer blev student i Uppsala 1677, antogs 1680 till 'ämnesven' vid Antikvitetskollegium och blev 1682 kanslist. Han erhöll sedan i uppdrag att i sällskap med Johan Hadorph göra resor i landsorten för att uppleta och avteckna gamla minnesmärken och runstenar. Då samlades det första materialet till det stora runstensverk, som längre fram utgavs under namn av Bautil.
Sedan han 1689 blivit assessor i Antikvitetskollegiet, ägnade Peringer sig huvudsakligen åt samlandet av ett svenskt diplomatarium samt genealogier. 18 folianter förstördes visserligen vid slottsbranden 1697, men arbetena gjordes om, och han lämnade efter sig betydande, hos Vitterhetsakademien förvarade avskriftssamlingar ('Bullarium', m.m.; se art. Svenskt Diplomatarium). 1693 blev Peringer efter Hadorph sekreterare vid Antikvitetsarkivet och riksantikvarie samt adlades samma år med namnet Peringskiöld. Han var 1698-1711 ä...
Keere, Pieter van den [Kaerius, Petrus]
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...

Cassini de Thury, César-François
Biografiska uppgifter:17 June 1714 – 4 September 1784
César-François Cassini de Thury (17 June 1714 – 4 September 1784), also called Cassini III or Cassini de Thury, was a French astronomer and cartographer.
Cassini de Thury was born in Thury-sous-Clermont (Oise), the second son of Jacques Cassini and Suzanne Françoise Charpentier de Charmois. He was a grandson of Giovanni Domenico Cassini, and would become the father of Jean-Dominique Cassini, Comte de Cassini.
In 1735, he became a member of the French Academy of Sciences as a supernumerary adjunct astronomer, in 1741 as an adjunct astronomer, and in 1745 as a full member astronomer.
In January, 1751 he was elected a Fellow of the Royal Society.
He succeeded to his father’s official position in 1756 and continued the hereditary surveying operations. In 1744, he began the construction of a great topographical map of France, one of the landmarks in the history of cartography. Completed by his son Jean-Dominique, Cassini IV and published by the Académie des Sciences from 1744 to 1793, its 180 plates are known as the Cassini map(fr).
The post of director of the Paris observatory was created for his benefit in 1771 when the establishment ceased to be a dependency of the French Academy of Sciences.
His chief works are: La méridienne de l’Observatoire Royal de Paris (1744), a correction of the Paris meridian; Description géométrique de la terre (1775); and Description géométrique de la France (1784), which was completed by his son ('Cassini IV').

The Cassini projection is a map projection described by César-François Cassini de Thury in 1745. It is the transverse aspect of theequirectangular projection, in that the globe is first rotated so the central meridian becomes the 'equator', and then the normal equirectangular projection is applied.
In practice, the projection has always been applied to models of the earth as an ellipsoid, which greatly complicates the mathematical development but is suitable for surveying. Nevertheless the use of the Cassini projection has largely been superseded by the Transverse Mercator projection, at least with central mapping agencies.
Areas along the central meridian, and at right angles to it, are not distorted. Elsewhere, the distortion is largely in a north-south direction, and varies by the square of the distance from the central meridian. As such, the greater the longitudinal extent of the area, the worse the distortion becomes.
Due to this, the Cassini projection works best on long, narrow areas, and worst on wide areas.
