Glen Jacob Culler (July 7, 1927 – May 3, 2003) was a 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. He later served as director of the UCSB Computer Center and professor in the College of Engineering and extended his revolutionary view of the role of computers to include their use in the classroom. He left UCSB to work in industry and establish his own company, called Culler-Harrison, in 1969. Culler-Harrison became CHI Systems, and later, Culler Scientific.
One of Glen Culler's sons, David Culler, is a notable computer scientist in his own right. Another son, Marc Culler, is a distinguished pure mathematician working in low-dimensional topology.
Culler was the developer of the Culler-Fried Online System, one of the first interactive computer systems in the mid-1960 era. This was the first system to make use of a storage oscilloscope as a means of presenting graphical information, and provided an innovative means of presentation and teaching of mathematical concepts. One of the first object oriented approaches to computing, the system provided a set of operators (e.g., add, subtract, display, multiply, sin, exp) on a predefined set of mathematical objects: scalars, vectors, arrays, and matrices (2-D only, up to about order 30..33).
This interpreted programming language was named MOLSF for Mathematically-Oriented Language, Single-Precision, Floating-point. The MOLSF keyboard consisted of a modified double QWERTY keyboard with the second, upper keyboard, renaming all keys to various functions (special hardware which included APL keyboard capability, two generations existed). The graphical integration was nearly seamless, but memorization of commands was nearly impossible.
The CFS has a second programming language named COL for Card-Oriented Language, somewhat like modern day text-editors. MOLSF and COL didn't communicate very well. They were vastly different languages. The Culler-Fried System only ran at UCSB and TRW.
