Yes, that is the one. They both have two e's, isn't that close enough?

Amazing, I did not see any mention yet of perhaps the best known American designer of a steam locomotive, Ephraim (sp?) Shay. Thousands of shay locomotives were built for around sixty years. Certainly other designers at Lima contributed to the updating of these locomotives and their names deserve to be remembered also. But the name shay is known not only in the U.S. but around the world.

Perhaps the reason that designers or engineers in almost any field are remembered is because their name is promoted, either by themselves or by the businesses that employed them or used their designs. So they are eventually 'discovered' by historians because their names are the most prominent ones preserved in literature and historical records.
Also, as I believe has been mentioned, in the UK they have a much higher level of public interest in the history of science and technology, which may explain the fame of many of their locomotive designers. I note the BBC story in flimsies about a new boiler for the Flying Scotsman. Somehow I doubt if that news would have been in a national publication in the US.

Of all the US steam designers, the only one who was a self-promoter was Samuel Vauclain of Baldwin. Andre Chapelon of France certainly was as well. The names of some of the PRR CMO's like Duer and Vogt are known to SPF's, but then PRR built a greater proportion of its own power than most.

But Sam Vauclain was not only a prolific designer, he was a peripatetic salesman for Baldwin as well!
