I was a Western student between 1976 and 1982 and a talmid of Dr. Block zt”l. Together with other students we learned Chumash weekly in his office. I was not religious at the time but I occasionally ate at his home and saw him in shul. He was instrumental in the completion of my Masters thesis on the Rambam’s views on the concept of the body and health. I remember him vividly riding his bike to campus and the incredible respect he had from his colleagues in the philosophy department. I continued my graduate studies at the University of Tennessee-Knoxville… Read more »

B.H. Dear Shmuely and entire Block family, Your father, Dr Block, had a profound impact on me.

When I was on shlichus as a bachur at the Yeshiva in New Haven, your father was gracious enough to speak more than once, per our request, at Yale University.

Fahbrengens, overnight meetings, staying at his home for 9 days over Sukos, and this, and so much more, caused a complete change in my perspective on life. He and his family inspired me to understand Judaism and Khassidus as the ultimate Truth.

My zaidy always had a smile on his face, and was cracking jokes. He was also the most caring and loving zaidy, always making his grandchildren eggs and giving them lollypops. A true chossid.

A truly special man. A legend who I’m proud to call my Zaidy. We miss him so much already

What a loss this is for us all. I remember hearing Dr Block years ago at the pgishas in New York and later he came to our community in San Diego to speak. Such a humble but brilliant man with such love for everyone.

Should probably be: “this is NOT to be taken as an advocacy by the Rebbe”.

Probably a typo.

In an interview with JEM, he said it was the Rebbe who made him a “great philosopher”. The Rebbe had encouraged him to complete his doctorate, and held him up as an example for his commonly stated position that it is not a contradiction for someone with a higher education, even a “great philosopher”, to be a frumme Yid, and even a lubavitcher; For science does not inheritably contradict Torah. (This is be taken as an advocacy by the Rebbe for someone already a lubavitcher to get a higher education. Rather that someone who already has higher education should not… Read more »
