Bestselling author and New Orleans native Walter Isaacson will host the first national signing of his new book, “The Code Breaker: Jennifer Doudna, Gene Editing, and the Future of the Human Race,” on Saturday (March 13) at a private home in the Garden District. The book is an account of how 2020 Nobel Prize winner Jennifer Doudna and her colleagues launched a revolution that allowed us to cure diseases, fend off viruses and have healthier babies. Isaacson will share his insights into the work of Doudna, which is increasingly topical as we navigate through this pandemic and aim to understand the technology behind the new vaccines.
