The book describes, and where possible illustrates, historic mechanical engineering landmarks, representing the accomplishments of mechanical engineers over the past 250 years-from the steam engine of Thomas Newcomen (1712), which launched the Industrial Revolution, to the Saturn V rocket (1967). Some of them are recognizable to us all, such as Xerography, Sikorsky’s helicopter, and Disneyland’s monorail. Others work behind the scenes or have been superseded, such as the Owens “AR” bottle machine and the Jackson Ferry Shot Tower. The landmarks are grouped into such categories as mechanical power production, power transmission, minerals extraction and refining, food processing, environmental control, transportation, biomedical engineering, and communications and data processing. Each section is introduced by an essay that helps place each landmark into the context of technical and general history. While some of these landmarks have not survived intact, others can be visited, and travel information is provided. The machines that shape our society help educate us about an important facet of human history and how technology has influenced it. ASME International’s landmarks program identifies and recognizes artifacts of significance before they disappear. This roster of landmarks tells a magnificent story of people and places and of innovation and discovery.
