Hanne Strager is a biologist and acclaimed science writer. Her books include The Killer Whale Journals: Our Love and Fear of Orcas (2023), which received a National Outdoor Book Award. She is the director of exhibitions of The Whale in Norway and was formerly the director of exhibitions at the Natural History Museum of Denmark.

Inge Lehmann deserves renewed attention not only for her contributions to illuminating the internal structure of our planet—which were fundamental indeed—but also for her accomplishments in the face of many professional and personal challenges. If I Am Right, and I Know I Am is a story of defiance, resilience, and, against many odds, startling professional achievement. But even more revealing, this is a story of the foundational personalities and interpersonal relationships during one of the most productive times for geology, when subfields like seismology were contributing to paradigmatic shifts in our understanding of a dynamic Earth.
