Episode 2 of the Podcast on the Family of Julio Metal

“Recovering Ned” is online

A few day ago the second episode on the son of Julio Metal of the podcast by Loss & Found Productions was released.

Julio Metal was a banker and entrepreneur who lived in Berlin and Vienna. His assets were “Aryanized” starting in 1933. In 1938 he emigrated to the USA. He died there in 1941.

Facts & Files was commissioned by Julio Metal’s granddaughter, Camilla Brinkman Metal, to research the “Aryanization” in Berlin and Vienna archives.

These sources and others were the basis for the podcast Camilla produced about her family history.
