Dr. Nathaniel H. Leff was a professor of Economics at Columbia University Business School for over twenty-five years. Among his published books are two volumes on "Underdevelopment and Development in Brazil" which is being translated in Portuguese and taught in Brazilian Universities. A reporter for a Brazilian newspaper wrote a fascinating article about Dr. Leff's academic influence. More on his academic carreer
For years, Nosson Chayim Leff wrote a weekly "email on the Sfas Emes" (available here), and finally wrote a sefer, Emes Ve'emunah, A Sfas Emes Companion, published by Menucha publishers.
Dr. Leff and Nosson Chayim Leff were the same person.
He had a very positive influence on many people through his multi-faceted personality.
We would like to recommend that people who wish to give charity in Dr. Leff's name donate to their local Bikur Cholim or any other organization that helps the handicapped.
A pioneer in the field of food technology and kashrut, Dr. Judith Leff was a brilliant biochemist who bridged the gap between Halacha and complex molecular biology. As a trailblazing consultant for the OU, she used her vast scientific expertise to revolutionize ingredient oversight, leaving an indelible mark on the global kashrus industry through her professionalism, education, and profound commitment to Torah and science.

Twenty-two years ago, we moved to Passaic, New Jersey to be near our daughter and son-in- law, Chana and Dovid Laks. At that time, my husband’s Parkinson’s disease was already quite advanced. We were very concerned that my husband would be completely isolated in a new community, among people who had not known him in his prime.
Our experience, once we moved here, was beyond our wildest dreams. The Passaic community embraced him with all their heart and tried to help him in every aspect of his daily life.
This included:
Organizing a rotation so that my husband could go to shul every day.
Taking him to ball games
Sitting by him in shul to help with his Talis and his siddur.
Computer assistance; he had so many difficulties with his computer
Inviting him to those wonderful Purim seudos where he could relive our Purim at home
Arranging for Rosh Chodesh minyanim in our house when he could no longer attend shul
Blowing shofar at our home
Driving him to Manhattan to the Hospital for Special Surgery
The many, many visitors
The, at least, seven chavrutot who came to our house every week.
The special attention given to my husband when he was in the emergency room in Hackensack.
The visitor who continued coming on Shabbos to the very end, even after my husband had become nearly totally unresponsive
On behalf of myself and my children, I would like to thank every person who helped my husband during the twenty two years he lived in Passaic. And I very much hope that my husband z”l will be a meilitz yosher (heavenly intercessor) for this extraordinary community.
