No question that there was a community of Blues players in the 1950s who popularized the idea, BB King probably being the most influential. Interestingly, you can hear even earlier examples here and there.
One of the really great, relatively obscure players who pioneered that style was Carl Hogan of the Louis Jordan Big Band. Check out the intro lick to "Ain't That Just Like a Woman" from IIRC the late 1940's. If it sounds familiar, it's probably because Chuck Berry "borrowed" it for (arguably) the most famous bit of rock n roll guitar ever, the intro to "Johnny B Good"
