Named after Längenfeldgasse, which honours the benefactor Josephine Haas von Längenfeld.
The street was named on 5 July 1894 after Josephine Haas von Längenfeld-Pfalzheim. She founded the children’s day nursery in Meidling and a fund giving dowries to poor girls. Born in Burglengenfeld in the Upper Palatinate, she was ennobled by the King of Bavaria and died in 1846. Sources give her birth year as 1782 or 1783.
