description Phyllis Pearsall Overview

Phyllis Pearsall was a British cartographer and publisher who founded the Geographers' A-Z Map Company. She is best remembered for creating and publishing the first London A-Z street atlas in 1936, a comprehensive pocket-sized navigation guide designed for pedestrian and driver use.

help Phyllis Pearsall FAQ

Did Phyllis Pearsall really walk every street in London to make the A-Z?

The famous story says Pearsall walked thousands of miles through London while compiling street names, but historians have challenged the most heroic versions of that account. What is clear is that she built the Geographers' A-Z Map Company and successfully marketed a highly usable street atlas.

When was the first London A-Z street atlas published?

Pearsall's company published its first London A-Z street atlas in 1936. Its indexed format helped users locate a street by name and then find it on a numbered map page.

Why was the London A-Z easier to use than older street maps?

It paired clearly drawn map pages with an alphabetical street index in a portable book. That meant a user could look up an unfamiliar road without unfolding a large sheet map.

Does the Geographers' A-Z Map Company still exist?

The A-Z name survived Pearsall and became closely associated with British urban navigation. Printed A-Z atlases later faced competition from satnav devices, Google Maps, and smartphone navigation.
