Reply To: Where have all the Yekkes gone?

Genetics. Yekkishkeit is generally passed from father to son (with a few notable exceptions, like one of Rav Breuer’s daughters who married a Litvak but raised her kids to wear tallios and wait three hours) . So if a yekke has no children, or only daughters, it’s unlikely his grandkids will be Yekkish. So every generation there are fewer and fewer tallios in middle school.
