In this episode, Jerry visits the Library of Congress in Washington DC to meet senior librarian Iris Taylor, who has nearly five decades of experience in the map department.

Iris shows Jerry a series of beautiful pictorial maps, created in the 1940s by the pioneering geographical storyteller Louise E. Jefferson. In particular, she highlights a map of ‘Americans of Negro Lineage’ from 1946. This map showcases notable African-Americans from throughout history, including figures like Harriet Tubman - who helped establish the Underground Railroad for escaping slaves - and the poet Langston Hughes. 

Louise was one of the first female African-American cartographers. Her work was long neglected, and Iris is working to bring it back to light.

In this conversation, Iris reflects on her discovery of the Jefferson maps, and the profound impact they have had on her. She also talks about her own personal journey as a librarian at the largest and most comprehensive map collection in the world. 

From historians, scientists and writers to creatives and cultural custodians, people have used maps as a source of knowledge, guidance, and inspiration for centuries.

Join award-winning expert Professor Jerry Brotton as each episode he invites a guest to share a map close to their heart - and unfurl the ideas, inspirations, and stories behind it.

So if you’re fascinated by history, art, adventure and culture, why not become part of a global community of fellow explorers as we ask - What’s your map?
