RIP: Gordon Bell, a true visionary of the computer age, has passed away at the age of 89. The computing luminary leaves behind an incredible legacy as one of the key architects who helped usher in the modern era of minicomputers and personal computing.

The news of Bell's death on May 17 in Coronado, California was shared by his friend John Mashey, a Bell Labs veteran. Mashey paid tribute to Bell as a "famous computer pioneer, a founder of Computer Museum in Boston, and a force behind the @ComputerHistory here in Silicon Valley." The cause was aspiration pneumonia.

Born 1934 in Kirksville, Missouri, Bell displayed an incredible knack for experimentation from an extremely early age. According to The New York Times, he faced health challenges as a young child. But with time on his hands during those bouts of illness, the future computing pioneer would occupy himself by wiring circuits, conducting chemistry experiments, and solving intricate puzzles.

Bell's groundbreaking work really took off in the 1960s at the companies Digital Equipment Corporation (DEC) and later Encore Computer and Ardent Computer, both of which he founded. Under DEC, he was instrumental in designing the first major minicomputer hits like the PDP-8 in 1965. There, he also invented the first UART (Universal Asynchronous Receiver-Transmitter) for serial communication.

The PDP-8 represented a radical shift from the dominance of expensive, room-sized mainframe systems that were off-limits to most people. The PDP-8 and its successors lit the fuse for the personal computing revolution to come. In fact, the PDP-8 was one of the key machines on the ARPANET network that later became the internet.

Bell had an uncanny knack for envisioning where computing needed to go next. For instance, after joining Microsoft Research in the 90s, he spearheaded an ambitious project called MyLifeBits – a cloud database aiming to digitally capture one's entire lifetime of data like emails, photos, and videos.

Throughout his career, Bell took on many roles – researcher, inventor, entrepreneur, teacher, and more. He was awarded the National Medal of Technology and Innovation in 1991 and even served a stint at the National Science Foundation helping build early internet infrastructure.

Industry veterans like Microsoft's Satya Nadella and former CTO Ray Ozzie have been sharing heartfelt tributes. Ozzie recounted how Bell, along with legends like Jim Gray and Butler Lampson, provided invaluable mentorship during his early years at Microsoft, saying "I could never have survived or made any kind of impact without these three."

The industry has truly lost an icon and pioneer. But Bell's daring designs, bold thinking, and passion for progress will remain an inspiration for generations of technologists to come.
