The steam engine is still regarded today as the most important symbol of industrialization and revolutionary technological progress. This work, first published in 1901, provides a vivid portrayal of its fascinating historical development and its socio-cultural significance. Matschoss traces the history of the steam engine from its beginnings through a wealth of illustrations, graphics, and a detailed timeline. Conrad Matschoss (1871-1942) was an engineer, university lecturer, technology historian, publicist, and director of the Association of German Engineers. In addition to numerous publications, one of his key achievements was the introduction of the history of technology as a scientific discipline and field of study. He was also the founder and editor of the yearbook 'Contributions to the History of Technology and Industry'.
