Jiri Stern

This is a photo of my brother, Jiri Stern. My brother, Jiri Stern, or Juraj Stern, was born in 1921. He died in 1999. After the war he graduated as a mechanical engineer. He was an excellent student. Back then the Letnany airport in Prague had announced a competition, because they needed a mechanical engineer, who they'd then put through aeronautical engineering school. My brother applied and they took him too. He devoted himself only to math and some calculations. He wrote books and had all sorts of professional articles published. His wife Helena worked as a secretary at CKD Sokolov. They were childless.
