Scofield was a big moment for sure. But the Zionism was deeply entrenched in the elite WASPS before that via British Israelitism. J H Allen's Judah's Scepter came out a few years before Scofield as well.
And of course it was Jewish financed. Sassoon and Montefiore and Rothschild etc etc.
I will post pic later but JC Gawler in 1875 released Our Scythian Ancestors and his family was as elite as it gets (he was Keeper of the Jewels). They were also huge zioinists and in with the Sebags and Montefiores on the project.
