Íàçâàíèå: From galaxies to turbines : science, technology, and the Parsons family

My interest in the achievements of the Parsons family dates back to the 1960s when I began teaching in the Engineering School at Trinity College Dublin. Each day as
I went into the stylish Museum building to reach the lecture theatres, I passed a number of glass cases in the entrance hall. One of these housed 'Steam turbogenerator
N° 5, 1885', presented by Gerald G Stoney BA, BAI. Time passed, and as 1984, the centenary year of Charles Parsons' invention, approached I became
increasingly interested to know exactly how this had been conceived. Also, among other items which the Engineering School possessed was a model of the 3 ft
reflecting telescope built by Charles' father William, the third Earl of Rosse at Birr Castle, and this alerted me to the importance of Birr in the story. While preparing for
the International Parsons Steam Turbine Conference, which was held in Dublin, several questions came to mind. Why was the turbogenerator invented in 1884, and
not 1834 or 1934 for example? Why was it Charles Parsons that accomplished this? How did it happen that its development took place in Newcastle upon Tyne and
not in Belfast or Dublin? The centenary was marked in 1984 by a conference at Trinity College Dublin and by an Exhibition at the Heaton Works of C A Parsons and
Co in Newcastle upon Tyne, but the lack of any nationwide celebration in Great Britain of this most significant of engineering achievements only seemed to confirm the
correctness of the title which Joe Clarke chose for his 1984 booklet, 'An almost forgotten great man, Charles Parsons'. As I worked with the artefacts and archival
material, an awareness of the personalities of the two great men, William and Charles Parsons, began to emerge. My hope is that I can convey something of that to the
reader. In the nature of the story, technical details have an essential place, and I have tried to describe them in a way that will satisfy the reader who is not an expert.
At the same time this is not an attempt to write a complete history of the steam turbine.
