Does CCD Idea Really Belong to Smith and Boyle?

IEEE Spectrum Tech Talk blog has two posts questioning Smith’s and Boyle's ownership of the CCD idea (Post #1, Post #2 with comments). The posts suggest that the idea originally came from their Bell Labs collegue Eugene Gordon.

Thanks to E.F. for sending me the link.

Update: As said in comments, there is another post saying that the CCD idea originator is Michael F. Tompsett.
