Engelsk karthandlare i början av 1700-talet, bosatt i London. Enligt honom själv handlade han med 'franska och holländska kartor till de fördelaktigaste priserna'. Vidare rekommmenderar han sina alla typer av 'Spectacles, Reading Glasses, Tellescopes, Perspective Glasses' etc. och uppmanar 'all the Artists in the Universe' till att komma till honom. Tooley upplyser torrt att han var lika mycket leksaksfabrikant som karthandlare. Han nämner dock ett antal kartor, samtliga utförda runt 1720.
1754-1820.
Ellicott, a Quaker, was raised in Bucks County, Pennsylvania. His father was a prosperous miller whose family founded Ellicott City, Maryland in 1775. Andrew Ellicott was trained to be a mathematician and surveyor. He conducted several large surveys with David Rittenhouse, the Philadelphia astronomer, mathematician, and clockmaker. President Washington in 1791 asked Ellicott to survey the bounds of the District of Columbia. The following year Washington asked him to complete L'Enfant's plan for the city. Ellicott made some changes to L'Enfant's plan. He changed the alignment of Massachusetts Avenue, eliminated five short radial avenues, added two short radial avenues southeast and southwest of the Capitol, and named the city streets. In less than one month Ellicott had a plan ready for the engravers. A few months later Ellicott, like L'Enfant, found himself at odds with the Commissioners and resigned from the project.

Italiensk boktryckare och förläggare som verkade i Venedig i slutet av 1700-talet. 1797 fick han titeln stadsboktryckare. Zatta utvecklade en omfattande bokproduktion som är känd främst för alla vackra illustrationer (frontespis, vinjetter, friser m.m..). Under åren 1779-85 utgav han en 'Atlas novissimo' med 218 kartor.

Frisius, Gemma. [Reinerszoon, Jemme.]
Biografiska uppgifter: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 to describe how an accurate clock could be used to determine longitude. Jean-Baptiste Morin (1583–1656) did not believe that Frisius' method for calculating longitude would work, remarking, 'I do not know if the Devil will succeed in making a longitude timekeeper but it is folly for man to try.'
Frisius created or improved many instruments, including the cross-staff, the astrolabe and the astronomical rings. His students included Gerardus Mercator (who became his collaborator), Johannes Stadius, John Dee, Andreas Vesalius and Rembert Dodoens.
A lunar crater has been named after him.
