Indian Empire (1888)

John Bartholomew Junior (1831–1893) and his son John George Bartholomew (1860–1920) brought the firm to prominence as the renamed 'Edinburgh Geographical Institute'. In particular, J.G. Bartholomew made the firm a publisher of its own works, rather than a producer of maps for other firms. John (Ian) Bartholomew (1890–1962) oversaw the Times Survey Atlas of the World (1922) and later the Mid-Century Edition of the Times Atlas of the World (1955–60).

The cartographic tradition continued into a fifth family generation. John Christopher Bartholomew (1923–2008) shared his ancestors' fascination with the natural sciences, their meticulous standards and spirit of enterprise, and oversaw the publication of some of the most detailed maps of the last century, including The Times Comprehensive Atlas of the World (1967).
