Access to materials

Portions of this collection have restricted access; the remainder of this collection is open for research; access requires at least 48 hours advance notice. Because of the nature of certain archival formats, including digital and audio-visual materials, access will require additional advanced notice. Copies of digital files may be provided for use in the SCRC Reading Room upon request.

The James O. Henriksen Papers contain letters and correspondence, software-related lectures, articles, books, and other materials related to James O. Henriksen's career in computer simulation and computer science from the early 1960s into the 2000s. The collection provides information on the program that Henriksen created called GPSS/H, his other endeavors related to computer simulation, and some information about his company, Wolverine Software. The materials in this collection also show Henriksen's involvement with other indivuduals in the field of computer simulation, his time as a teacher, and correspondence from users of his GPSS/H software. Materials range from 1963 to 2016.

James "Jim" O. Henriksen (1945-2019) was the founder and CEO of Wolverine Software Corporation, which he established in 1976. During his career, he developed GPSS/H for IBM mainframes in 1977, enabling the continuing support of a major simulation programming language. The first commercial installation of GPSS/H was made at General Motors Manufacturing Department, and in the following years the application was expanded and improved. Wolverine also developed other software innovations, including Proof Animation, which was introduced in 1989, and SLX, the extensible simulation language, a later product.

Biographical/historical note

James "Jim" O. Henriksen (1945-2019) was the founder and CEO of Wolverine Software Corporation, which he established in 1976. During his career, he developed GPSS/H for IBM mainframes in 1977, enabling the continuing support of a major simulation programming language. The first commercial installation of GPSS/H was made at General Motors Manufacturing Department, and in the following years the application was expanded and improved. Wolverine also developed other software innovations, including Proof Animation, which was introduced in 1989, and SLX, the extensible simulation language, a later product.

Henriksen was active in the computer simulation field and taught numerous graduate-level computer courses, including classes at the Virginia Tech Northern Virginia Center. His research and scholarly contributions have been presented at conferences including the Winter Simulation Conference. His published works have appeared in several journals. Henriksen's professional interests include the construction of compilers and run-time support for discrete-event simulation and animation. During his career he helped to develop eight compilers and five generations of animation software. Henriksen was named a Titan of Simulation at the 2006 Winter Simulation Conference.
