Rabbi Yaakov Menken's letter that went out on the World Wide Web to let readers know of Arthur's passing.

Last week, we lost a man who did what is difficult to imagine: as a successful businessman, he not only migrated to Jewish observance, but set aside his expertise to sit at the feet of teachers -- as if he were a young child -- to learn Torah.

Arthur Morgenstern spent his later years going to the Yeshiva of Philadelphia every morning, paying attention to the words of Abbayeh and Rava rather than the latest investment opportunities. He learned with people many years his junior, in order to learn to swim in the Sea of Talmud. And his accomplishments were considerable, to say the least -- I had the opportunity to attend a Siyum (celebration of completion of a Tractate) which he made a few years ago, and know that this was but one of his many accomplishments in learning.

His investments turned to Torah as well, as many Jewish institutions in Philadelphia and beyond gratefully attest. One of his most recent projects was to help found the Philadelphia Kollel, which is just getting underway. A Kollel, an advanced study center for Jewish scholars, often serves a crucial role in the development of an affiliated Jewish community -- and it was surprising that there was none in Philadelphia. Arthur recognized the need.

And I must also mention that he was the founding Chairman of the Board of Project Genesis -- in fact, he helped me to incorporate Project Genesis in 1993. He was one of the first to believe in Project Genesis and what it might accomplish. Today, what we provide to nearly 40,000 subscribers is in his merit.

Aharon ben Binyamin a"h will be sorely missed, by his family and by all who knew him.
