Carl Sassenrath - History
Carl Sassenrath is the founder and CTO of REBOL Technologies. He is best known for his original design and implementation of the Amiga Multitasking Operating System.
Sassenrath grew-up in the town of Eureka in Northern California where he became interested in broadcast television and film production. In the early 70's he landed a job as a cameraman at the local ABC network affiliate and worked his way up to being a director before graduating from high school. It wasn't until Sassenrath attended the University of California, Davis, that he was first exposed to computers as a tool to help simulate brain function while he worked as a neuro-physiology research assistant. It was this work in neuroscience that inspired him toward inventing new methods of distributed computing in the years that followed.
Before he graduated, Sassenrath was recruited in 1979 to the Hewlett Packard Computer Systems Division as an operating system engineer, during which time he also completed his degree at Davis and graduated with a B.S. in Electrical Engineering in 1980. At HP, he focused on the design and performance of HP's MPE operating system kernel.
In 1981 Sassenrath took a break from HP and joined an Antarctic research team from Stanford University as a research scientist at the South Pole. Returning to HP in 1982, Sassenrath engineered one of the first graphically oriented user interfaces (GUI).
The resources provided at HP allowed Sassenrath to carefully study the design of every operating system of the day and develop new system concepts around parallel processing and distributed computing. When Amiga Computer, Inc. extended an invitation to Sassenrath in 1983, they promised that he could write whatever operating system he wanted for use in the new Amiga computer.
After Amiga, Sassenrath joined Apple Computer Advanced Technology Group, where he lead the development of a next-generation object-oriented operating system for a secret parallel processing computer that was to eventually replace the Macintosh.
In 1988, Sassenrath escaped from Silicon Valley lifestyle and bought a ranch in Northern California where he designed and built a house, planted a vineyard and now makes his own personal label of wine. Located in a small mountain community, Sassenrath has continued his pursuit of distributed system technologies by founding Pantaray, Inc., American Multimedia, and Videostream, Inc. - all of which provided various multimedia solutions, including Internet TV set-top boxes, CDTV (the world's first CD- ROM TV set-top box), and content authoring systems.
In 1996, Sassenrath set aside all other work to focus solely on his vision of creating a new distributed computing architecture for the Internet, and he founded REBOL Technologies, located in Ukiah, California.

"We're uniting the world of computing when so many others are pulling it apart," says Carl Sassenrath, CEO of REBOL Technologies (
Says Sassenrath, "REBOL is quickly emerging as the de-facto standard for all those network communication tasks that web developers, programmers and system administrators deal with on a daily basis."
REBOL Technologies was founded in March 1998 by Carl Sassenrath, the creator of the multi-tasking AmigaOS.

About REBOL Technologies, 15 June 2015 [cached]
REBOL Technologies was founded in 1997 by Carl Sassenrath.
For more than 20 years Carl Sassenrath has been leading the design and implementation of fundamental advances in computer languages, operating systems, and distributed computing.
In 1985 Carl was responsible for the design and implementation of the highly acclaimed Amiga Multitasking Operating System. His background includes senior development roles at Apple Computer's Advanced Technology Group, Hewlett-Packard (Computer Systems Division), and Commodore Amiga.
Carl was also the founder and president of Pantaray and American Multimedia, and was the co-founder and VP of Development for Videostream Inc. Carl has headed the development of Internet set-top boxes, CDTV (the world's first CD-ROM set-top box and precursor of DVD), programming languages, and multimedia content authoring systems.
Carl holds a BS in Electrical Engineering and Computer Science from the University of California.

Sassenrath asserts, "Developers and the technologists have been shortchanged by existing languages and trapped in a quagmire of unproductive, bureaucratic complexity.
Led by Carl Sassenrath , his team of language and network architects built REBOL by drawing on their decades of experience in both academic theory and real-world practicality. The result is a language that REBOL Technologies believes will appeal equally to theoreticians and to Internet technologists.
Prior to founding REBOL Technologies, Carl Sassenrath's professional experience spanned eighteen years in operating systems, computer languages, multimedia systems, and management. While a manager at Commodore Amiga in the mid-1980s, Mr. Sassenrath led the design and implementation of the highly acclaimed Amiga multitasking operating system. As the president of Pantaray, Inc. in the early 90s, he headed the development of several multimedia software products, including television set-top boxes, CD-ROM based computers, programming languages, content authoring systems, and digital video tools. His background also includes management and engineering positions at Apple Computer and Hewlett-Packard.
