Glen Jacob Culler (July 7, 1927 – May 3, 2003) was an American professor of electrical engineering and an important early innovator in the development of the Internet.
Culler joined the University of California, Santa Barbara (UCSB) mathematics faculty in 1959 and helped put the campus in the forefront of what would become the field of computer science.
Culler's online system was chosen by ARPA to be one of the first four nodes on the original ARPANET in 1969, and with the University of California, Los Angeles (UCLA), participated in the first exchange of packets of data transmitted in the nascent Internet.
Culler-Harrison is occasionally cited as one of the precursors to the founding of Floating Point Systems, Inc. and the Very Long Instruction Word (VLIW) architecture by Joseph Fisher and James Ellis.
In 2000, President of the United States Bill Clinton awarded Culler the National Medal of Technology for his "pioneering innovations in multiple branches of computing, including early efforts in digital speech processing, invention of the first on-line system for interactive graphical mathematics computing, and pioneering work on the ARPAnet."
