Recognize A Family Member?

Ynet in cooperation with Bitmuna publishes a weekly dive into Israel's past with sepia photographs from a long time ago.

This week they are featuring photos of the dedication and construction of Hadassah hospital on Har Hatzofim (Mount Scopus).

The above photo shows Hadassah founder Henrietta Szold, future PM David Ben Gurion, journalist / Zionist activist Nachum Sokolov (I think he is the second one to the right of BG, clasping his hands) and future president Yitzchak Ben Tzvi (my guess - smiling lanky guy on the left) in 1936. The other people's identities are not known and the Bitmuna folks are asking the public to help identify them.

This is a photograph of two of the builders - identified only as 'sons of Jerusalem.' I imagine they are Jews.
