1831 Dower / Teesdale Map of the Eastern Hemisphere

John James Dower (June 1, 1825 - 1901) was a well-respected mapmaker, print seller, and publisher based in London, England. Dower is the heir to the more prominent London engraver and mapmaker John Crane Dower (1791 - 1847). Dower worked with many prominent middle to late 19th century London map publishers including Weller, Cassell, Bacon, Petermann, and others. He was elected to the Royal Geographical Society in 1854. Dower also published on maps his own account including one atlas and various school geographies. In addition to his cartographic work, Dower is well known as an engraver of military scenes.

Henry Teesdale (December 1776 - January 1856) was a British map publisher active in the first half of the 19th century. Teesdale was born in London. He was elected to the Royal Geographical Society in 1830. Teesdale initially partnered with John Hordan and William Colling Hobson as Henry Teesdale and Company, but this partnership was dissolved in 1832. Afterwards Teesdale continued to publish maps and atlases on his own account. He worked with several major British map engravers of the period including John Crane Dower, Christopher Greenwood, and Josiah Henshall, among others. His most prominent work is a large map of the world engraved by Dower. He must have enjoyed considerable commercial success because in 1845 he is registered as a partner in the Royal Bank of Scotland. Teesdale died in January of 1856 and was buried in All Souls, Kensal Green. Learn More...
