I would have thought such a simple combination would have been worked out much earlier. But I checked my 1993 copy of Robert Ulichney's "Digital Halftoning", and it only mentions 4. Floyd and Steinberg (1975), Jarvis, Judice, and Ninke (1976), Stucki (1981), and Stevenson and Arce (1985). Does anybody have a date for Atkinson's?
It was used on the Macintosh at release, so it must have predated Stevenson and Arce. I doubt that a description was formally published in the way that the others were. Wikipedia describes Atkinson's approach as a variant on Floyd-Steinberg dithering, and I imagine that he must have been aware of at least some of the prior work.
