A couple of items from the brilliant economist and Indonesian Minister of Finance, Sumitro Djojohadikusumo (also spelled Soemitro Djojohadikoesoemo), who Vlado worked with during his time in Indonesia, 1947 to 1951.

Here’s a copy of “Facing the Situation”, in which Sumitro lays out the economic challenges of post-war Indonesia, with a note to Vlado attached.

Also, one of the graphs in the book, showing Indonesian exports like pinang nuts, copra, quinine and sugar.

It was very nice of Sumitro to write a letter of introduction for Vlado’s sister to Mr. John D. Rockefeller III, but it looks like it wasn’t needed. An amusing find!
