The Lowinger family has helped build many yeshivos. Mesivta Chaim Shlomo (part of Darchei Torah) in Far Rockaway was built by a Lowinger. I believe Torah Temimah has a Lowinger’s name on the building.
There’s also a well known yeshiva in Brooklyn which has a very wealthy benefactor, but unfortunately, he wasn’t always honest about paying employees – mainly one, who went to Beis Din over it. The benefactor (who is employed by the yeshiva) refused to respond to the hazmanah (along with the Rosh Yeshiva).
