Eisemann family film

The list of children playing in this film is a partial but highly significant Who's Who of Torah education in America and abroad.
I want to know what their parents did that was so wonderfully effective!

There are eulogies for Miriam Elias, for instance, here and here. Rav Moshe Eisemann's shiurim are here. Shabbat.com is a next-generation Eisemann-family project.

The caption from the website is:

Uncovered Rare 1920's footage of German Jewish life!!

Personal videos of Hienrich (Chaim) Eisemann, taken in Frankfurt. The Eisemann family is of particular importance in the emergence of Jewish life in North America and Israel. The six children of Mr Eisemann are filmed. The children include: Clementine Bodenheimer (Wife of Dr. Ernest Bodenheimer) Taya Posen (wife of Rav Raphael - in laws of Karelitz from Benei Brak) Lola Grunfeld of London (Mother of Joey Grunfeld) Meier Eisemann (Founder of Laniado Hospital, Rav in Minnesota) Miriam Elias (Wife of Rabbi Joseph Elias) Moshe Eisemann (Noted Author)
