Negative Ascendees

I've been going through Ra, and re-read some interesing points.  This has inspired me to read biographies of saints of both polarities, to learn how to make my own choice and live accordingly.  According to Ra, Taras Bulba, Genghis Kahn, Rasputin all reached a level of polarization that allowed them to be harvested at any point in the cycle (pre-2012).  Himmler, and Goering "may be harvestable" possibly meaning that they will incarnate in this time to achieve their own ascension as they didn't achieve a level of negativity equal to that of Rasputin.  Also, at the time (1981), "others" (nazis) were still alive that were possibly harvestable.  Mengele died in '79, but I haven't read enough on the nazis to know of any other big names still alive at that/this time.

However, here's something I cam across:
"Questioner: Do you mean to say then that some scientists receive technical information, shall we say, telepathically that comes out then as useable gadgetry?

"Ra: I am Ra. That is correct. However, very positively, as you would call this distortion, oriented scientists have received information intended to unlock peaceful means of progress which redounded unto the last echoes of potential destruction due to further reception of other scientists of a negative orientation/distortion.

"Questioner: Is this how we learned of nuclear energy? Was it mixed with both positive and negative orientation?

"Ra: I am Ra. That is correct. The entities responsible for the gathering of the scientists were of a mixed orientation. The scientists were overwhelmingly positive in their orientation. The scientists who followed their work were of mixed orientation including one extremely negative entity, as you would term it.

"Questioner: Is this extremely negative entity still incarnate on Earth?

"Ra: I am Ra. This is correct."

Does anyone who knows there history better than I have an inkling as to who these scientists, both positive and negative were?
