what's the history of development of silica-reinforced tire rubbers? from where/whom did this breakthrough come?

Just guessing, I'd say it came from Degussa (company name, short for Deutsche Gold und Silber SA). They invented fumed silica in the quest for developing a "carbon white" process based on silica, analogous to the flame process for making carbon black.

When you consider that carbon black is the main reinforcing filler used in rubber, and Degussa is a major producer of carbon black, it could hardly have escaped their notice that this could be a potential application for silica.

You should be able to reconstruct the history of this technology from the patent literature, in as much depth as you want:

You can start with U.S. Patent 4,297,145, searching both the patents it references and the patents which reference it.
