For me that is more the mathmatical brains behind the idea rather than actual Engineering.
For me the real Engineers where Brunel and Tancred–Arrol etc. 24 year old Brunel built the Clifton Susspension bridge in Bristol in the 1800S. The others are people like John Barnard who brought a lot of inovations into F1.
I've always been greatly in awe of the works of Leonardo da Vinci, a lot of his ideas and inventions were indeed constrained only by the lack of proper materials. I once visited his home town where they have a museum dedicated to his works with models of some of them, the annoying thing being, none of them worked although it would have been relativley easy to do that, and would have given a better understanding of what he had achieved. And yes, Noldi, a brilliant mathematician also.
