Short History of Cadex
Isidor Buchmann started the company that turned into Cadex Electronics in the back room of his house that he built. One slide shows his young children jumping from the balcony above his workshop in the early 1980s. The challenge of starting a company singlehandedly led to rapid growth in the 1990s and beyond.
