The first paper established the existence of concurrent discovery experiments by Riccardo Giacconi and myself at the start of x-ray astronomy.\footnote{R. Giacconi \textit{et al., }Phys. Rev. Lett.\textbf{ 9}, 439 (1962).}$^{,}$\footnote{P. C.

Douglas \textit{et. al.,} eds.) Gordon and Breach Science Publishers, New York, p. 253 (1969).}$^{,}$\footnote{P. C. Fisher, BAPS \textbf{53} No. 2, 165 (2008).} Paper II \footnote{P.C. Fisher, plus FHP link to April 2009 presentation H14.00006.} described some acts by some individuals/institutions over four decades that may have caused the illusion that I had not made a discovery. Some additional data about this illusion, and the first possible measurement of x-ray emission from a black hole, will be presented. This paper's primary goal is for the American Physical Society to have Giacconi comment on several questions of a historical nature. \\[4pt] *Work supported by NASA contracts NAS5-1174 and NASw-909, the Lockheed Independent Research Program, and Ruffner Associates.
