The Rocket Lab: Maurice Zucrow, Purdue University, and America’s Race to Space focuses on the golden era of space exploration between 1946 and 1966, specifically the life and times of Purdue University’s Dr. Maurice J. Zucrow, a pioneering teacher and researcher in aerospace engineering. Zucrow taught America’s first university course in jet and rocket propulsion, wrote the field’s first textbook, and established the country’s first educational Rocket Lab. He was part of a small circle of innovators who transformed Purdue into the country’s largest engineering university, which became a cradle of astronauts. Taking a chronological and thematic approach, The Rocket Lab weaves between the local and national, drawing in rival universities, especially Harvard, MIT, Princeton, and Caltech. Also covered is Zucrow’s role in the national project system of research and development through World War II and the Cold War. At Aerojet, he was one of the country’s original project engineers, dedicated to scientific-technical expertise and the stepwise approach. He made vanguard power plant contributions to the Northrop Flying Wing, as well as the Corporal, Nike, and Atlas missiles, among others. Zucrow’s work in propulsion helped to improve the country’s arsenal of ballistic missiles and space launchers, and as a teacher, he educated the first generation of aerospace engineers. This book elevates Zucrow and the central role he played in getting the United States to space.

The first book to chronicle how innovation in laboratory designs for botanical research energized the emergence of physiological plant ecology as a vibrant subdiscipline Laboratory innovation since the mid-twentieth century has powered advances in the study of plant adaptation, evolution, and ecosystem function. The phytotron, an integrated complex of controlled-environment greenhouse and laboratory spaces, invented by Frits W. Went in the 1950s, set off a worldwide laboratory movement and transformed the plant sciences. Sharon Kingsland explores this revolution through a comparative study of work in the United States, France, Australia, Israel, the USSR, and Hungary. These advances in botanical research energized physiological plant ecology. Case studies explore the development of phytotron spinoffs such as mobile laboratories, rhizotrons, and ecotrons. Scientific problems include the significance of plant emissions of volatile organic compounds, symbiosis between plants and soil fungi, and the discovery of new pathways for photosynthesis as an adaptation to hot, dry climates. The advancement of knowledge through synthesis is a running theme: linking disciplines, combining laboratory and field research, and moving across ecological scales from leaf to ecosystem. The book also charts the history of modern scientific responses to the emerging crisis of food insecurity in the era of global warming.
