Yes, and Hugh Darwen (of third manifesto fame) was one of its developers for some years - I don't know if he was chagrined when IBM then assigned him to the SQL standards committee. There is a brief summary of BS12 written by Darwen somewhere on the web (and another by David Maier in one of his books, sorry I don't remember where and which). Maybe that's where Darwen mentions how the Yank IBM lab took a look and decided to go their own way (I suspect because they didn't understand it, Darwen is probably too polite to say that).

I believe some of the early bright relational lights such as Stephen Todd also worked on BS12. If the microprocessor and copious main memory had been dominant then, I wonder if developments might have ended up quite different.
