He did both; he invented a comprehensive system for recording in stereo, 
which included the 45/45 groove.

Others were working in the field; in the 1930s, the world was far less 
interconnected, and Bell Labs in the USA was probably unaware of the 
work of Blumlein in the UK, and vice versa.

I used to tell the students in my "Evolution of Audio Recording" class 
that the answers to the final exam could be summarized as The Three B's 
-- Bell Labs, Blumlein and Bing -- without significant error.
