First published in 2005, this book represents the first full length biography of John Phillips, one of the most remarkable and important scientists of the Victorian period. Adopting a broad chronological approach, this book not only traces the development of Phillips' career but clarifies and highlights his role within Victorian culture, shedding light on many wider themes. It explores how Phillips' love of science was inseparable from his need to earn a living and develop a career which could sustain him. Hence questions of power, authority, reputation and patronage were central to Phillips' career and scientific work. Drawing on a wealth of primary sources and a rich body of recent writings on Victorian science, this biography brings together his personal story with the scientific theories and developments of the day, and fixes them firmly within the context of wider society.
