Reply To: Remembering My Rebbi, Mattersdorfer Rav, Rav Simcha Bunim Ehrenfeld ztz”l

Should be above Shem Mishmuel reflecting Rav Shmuel’s ztz’l grandfather, the Chasan Sofer whose name was also Shmuel ztz’l. His sefer Chasan Sofer was named in respect to his father Rav Dovid Zvi Ehrenfeld ztz’l who was the son in law of the Chasam Sofer ztz’l. It also stands for חידושי תורת נכד סופר.
There heard a story where he was a business man with a grocery store. The customers were impressed as he and his son were arguing on a Meharsha.
