The bipolar junction transistor and light emitting diode are two innovations that have made a profound impact on the world. Professors John Bardeen and Nick Holonyak Jr., the respective inventors of these technologies, have also made a lasting impact on ECE ILLINOIS, where they spent the majority of their careers. This talk by Prof. Dallesasse reviews the men and their impact - both local and global - and also looks at some of the current work that ties their contributions together.
