From the author of the award-winning Visions of Linus Pauling comes this riveting sequel that chronicles four pivotal but under-studied aspects of Pauling's epic life: Pauling in Oregon — Uncover the roots of a genius, tracing his difficult childhood, his father's early death, his mother's struggles with mental illness, his transformative experiences at Oregon Agricultural College, and his tumultuous relationship with his alma mater in the years that followed. Caltech Administrator — Experience the largely untold story of Pauling's long administrative career as chair of the Division of Chemistry and Chemical Engineering, assessing his Caltech experience through a lens that is utterly unique within the literature and that situates the Institute's rise to prominence in part through Pauling's tremendous capacity as a leader. Period of Wandering — After resigning from Caltech in 1963, Pauling embarked on a decade-long journey of intellectual exploration. This part captures the essence of his professional transformation, during a period where the double Nobel Laureate struggled to find an institutional home and considered studying UFOs, among other subjects. Travels — Journey with Pauling across the globe, from his defining trip to Europe in the 1920s to a deep connection with Japan that lasted nearly five decades. Through his travels, including time spent with fellow Nobel Laureate Albert Schweitzer in Africa, Pauling's far-reaching influence and adventurous spirit come to life. Drawing on years of archival investigation, hours of interviews and hundreds of source materials, Chris Petersen offers readers an extraordinarily unvarnished view of Linus Pauling as never before — a young man, a bold division chair, and an intrepid explorer whose unorthodox ideas and fiery activism drew stormy interactions with friends and enemies alike. "This book outlines a comprehensive picture of the manifold elements of Pauling's varied life and career that should be of great interest to general readers as well as to those interested in biographies of scientific titans. The subjects covered here have not been addressed elsewhere in satisfactory detail. I am confident that it will would be as successful as its award-winning predecessor, Visions of Linus Pauling." Steve Lawson Former CEO, Linus Pauling Institute, USA "Chris Petersen's compelling new book follows on from his award-winning Visions of Linus Pauling and emphasises 'Pauling's relationship with physical, geographic and institutional spaces'. Drawing from the rich archives of the Pauling Blog, which Petersen curates, this biography offers fresh insights into Pauling's rise to prominence in theoretical chemistry and molecular biology, as well as the controversies that marked his later years. ... Engagingly written and meticulously researched, Petersen's new book deepens our understanding of Linus Pauling — still the only individual to receive two unshared Nobel Prizes — and his enduring influence on science and global peace."

He is also the founder, editor, and publisher of The Pauling Blog , which released original research on Linus Pauling nearly every week for over 13 years. In addition, he administers the SCARC oral history program and has led more than 200 interview sessions comprising in excess of 300 hours of content. He previously co-edited The Pauling Catalogue , a six-volume set describing the Ava Helen and Linus Pauling Papers, which are housed at Oregon State University Libraries. His first book for World Scientific, Visions of Linus Pauling , received an Outstanding Academic Title award from Choice magazine in 2023.
