R' Menachem Katz

The Chasam Sofer's Final Minutes "Ashrei Ish Sheba L'Kan V'Talmudo B'Yado" (Pesachim 50a). In the final days of his life, the Chasam Sofer reviewed all the Torah he learned in order to come to Shamayim with his Torah intact. In the last few hours of his life he realized that three Chiddushim of his were no longer clear in his mind. He quickly called for his close talmid, Rav Menachem Katz, who lived not to far from Pressburg, where the Chasam Sofer lay deathly ill.

Rav Menachem reviewed with him these chidushim and then the Chasam Sofer's face lit up content that he would return his neshama to Shamayim with all the Torah still with it. As soon as they finished reviewing, the Chasam Sofer screamed to Rav Menachem Katz, who was a Kohen, "Run out I am dying!" As soon as Rav Katz ran out, he heard the Chasam Sofer say Shema Yisroel as his Holy Neshama departed to the heavens.

Rav Katz later said about his Rebbi that he had such a good heart, that he held back the departure of his Neshama until he was sure that Rav Katz was safely outside without violating the Mitzvos of the Kohen.

"When Rabbi Yissachar Ber's daughter reached marriageable age, he approached the Chatam Sofer and requested him to suggest an outstanding disciple as a match for his daughter. The Chatam Sofer replied that he can suggest a very special match, the best student in the yeshiva, R. Menachem Katz of Prostitz, however, because he is a potentially leading Torah luminary, R. Yissachar Ber must undertake to support him for a number of years so he can study Torah without distraction. R. Ber did not hesitate and immediately agreed to the shidduch, however, he was financially hard-pressed..." https://il.bidspirit.com/ui/lotPage/source/catalog/auction/4181/lot...
