Josaphat Tetuko Sri Sumantya
A Life of Inventions

There was nothing more fascinating to five-year-old Josaphat Tetuko Sri Sumantyo than an array of defense systems in an air force base. His father, then a commander in the Special Task force used to take him to the base and then left him to wander alone. He was always drawn to the radar system at the base.

Young Josaphat then would ask the officers who were on duty, "Where were these made?" The officers showed him different radars made in different countries, the United Kingdom, Francebut none from Indonesia. It made an indelible impression on him, leaving him to wonder why his own country did not produce radars.
