Geographia (fl. 1879- present) Geographia, Ltd. was a London based cartographic publishing firm active from about 1910 until about 1985. The company was founded by Alexander Gross (1879-1958), a Hungarian immigrant to the United Kingdom. Geographia is best known for its folding pocket maps and globes. In the later part of the 1980s the firm was bought out by Harper Collins and continues to produces maps under the Collins Bartholomew imprint. Click here for a list of rare maps from Geographia.
