History of Rockwell hardness tests
(OP)
Can anyone recommend a source for historical information on this test? For example, where did the name Brale come from? There is a book by D. Tabor called Hardness of Metals, which is widely referenced, so that may be a good one. Any others? Thanks.

There is a library of technology at MIT (the Bitmer(?)) which might have the info you want. Then, again, you might want to check with the manufacturer, the Wilson Instrument Diivision of the American Chain and Cable Company, Inc.
I hope you post the answer to who, what, or where is "Brale."

Wilson Instruments is now owned by Instron Corporation.
I have access to the University of Michigan library, so I will be making a trip there soon to investigate.
I will post the answer about Brale if I find it.

I am working on a side project that will do just that on a very specific topic in metallurgy. I would say more but don't want to spoil the surprise (it will be some time in the making)
