A look back at friends and colleagues who left us in 2013.

Anyone who has walked through what used to be called a stereo store over the past 50 years has at some time no doubt heard music blaring from a Kenwood or Bose speaker. Bill Kasuga, who cofounded the latter, and Dr. Amar Bose, the genius behind the eponymously named Bose Corp, both left us this year, though their companies live on.

Other significant inventors who passed away were Dr. John E. Karlin, the Bell Labs engineer who designed the first touchtone phone keypad, and Gunter Erdmann, who held 13 patents for electronics materials and solder printing.

This year was particularly sad for the staff of UP Media, as we lost one of our own, Jerry Murray. Murray, the longtime West Coast editor for Circuits Assembly and PC FAB, passed away Jan. 13.

This month we reflect on their impact on our industry and our lives.
