Maps & America 2024

The Arthur Holzheimer Lecture Series

On April 11, 2024, the Arthur Holzheimer Maps & America Lecture Series presented “Newsroom Cartography,” given by Tim Wallace, Senior Editor for Geography at The New York Times.

Tim Wallace helps coordinate geospatial efforts across the newsroom in his role as Senior Editor for Geography at The New York Times. He creates visual stories that illustrate the geographic dimensions of current events. Tim has a Ph.D. in geography from the University of Wisconsin-Madison. For over 150 years, The New York Times has been using maps to help readers understand what is happening around the world. Cartographic techniques are integral to the way The Times reports on weather, war, climate, politics, and more. Using maps from the AGSL collections as touchstones, this talk will explore how The New York Times strengthens its news coverage with maps. This will be the 34th “Maps & America” lecture, supported by an endowment created by Arthur and Janet Holzheimer.

Take a look at the companion digital exhibit, Maps in the News.
