Grubb Dublin & Grubb Parsons: Telescope Makers


Ian S. Glass


Grubb Dublin & Grubb Parsons: Telescope Makers, the latest book by Dr Ian S. Glass, examines the history of one of the most important firms in the development of modern astronomical instrumentation. Focusing on Thomas Grubb, Howard Grubb, and the later evolution of Grubb Parsons, it situates their work at the intersection of scientific practice, precision engineering, industrial enterprise, and institutional astronomy. Through the history of telescope design, manufacture, and deployment, the book shows how technical innovation, commercial constraint, and observational ambition combined to shape modern astronomy, offering both a detailed account of a specialised instrument-making tradition and a broader contribution to the history of science and technology.
