Reb Meir Blau was the son of the הרב חיים משה יהודה הכהן בלוי - the מו"ל of the many Sifrei Rishonim. Reb Moshe Blau was a Mirrer Talmid, but he was also a brother-in-law of the Rebbe's mazkir, HaRav Chodakov. The latter was the one who was mekarev RMYHB to the Rebbe. Reb Meir wanted every Jew to know about the Rebbe, but there was one problem: The Rebbe could only reach so many people. 770 could only hold so many people. So he harnessed the power of the day, newspaper and Radio, and did all he could to let people know about the treasure to be found at 770. Seems like out of his own pocket. He also provided busing to some farbrengens, and later created the Crown Heights Hotline, which to many of us was the lifeline to 770 back in the day. You might say that it takes a Litvak/Yekke like Rabbi Blau to recognize what the Rebbe was and the need to "share" it with the rest of the world. If I may be so bold as to say that the Russians wanted the Rebbe all to themselves. They did n't want o share with "outsiders."
