Robert and James Stirling - A Biography
A considerably expanded new edition of Bob Sier’s 1995 book Rev. Robert Stirling D.D.
Starts with biographies of Robert Stirling, his brother James and Jame’s descendants many of who were also engineers. The second section of 151 pages covers the development of the early air engines up to 1845, followed by various patents and historical papers.
As the author says, very little detail is known of Robert Stirling's personal life, and much of the first section is drawn from University and Church of Scotland records.
A lot of technical information for the hot air enthusiast in the second section. 251 illustrated paperback pages.
