Rabbi Tzvi Hirsch Weinreb was the executive director of the Orthodox Union for a few years following the Rabbi Lanner scandal. A trained psychologist, Rabbi Weinreb served as a calming influence in light of the tumult going on at the time.
Note: R’ Weinreb and I had a very nice email conversation about this earlier. He wears it on all his Talleisim and is 100% convinced that the murex is the real source.
R’ Weinreb wears one full string (Raavad) and ties like the Chinuch.
