Norman I. Badler
Norman I. Badler, Rachleff Professor Emeritus in the Department of Computer and Information Science (CIS), passed away on May 15, 2025, at the age of 77.
A pioneering researcher, visionary educator and dedicated mentor, Badler earned a bachelor’s degree in Creative Studies (Mathematics) from the University of California, Santa Barbara in 1970, and a master’s in Mathematics in 1971 and a Ph.D. in Computer Science in 1975, both from the University of Toronto.
In 1974, Badler joined the Penn Engineering faculty as an assistant professor in CIS. He went on to serve in multiple leadership roles over his distinguished five-decade career, including serving as Chair of CIS from 1990–94 and as Associate Dean for Academic Affairs at Penn Engineering from 2000–04. He held the Cecilia Fitler Moore Professorship from 1990–94, and the Andrew S. and Debra Rachleff Professorship from 2013 until he earned emeritus status in 2021.
In 1998, Badler started Penn Engineering’s Digital Media Design (DMD) undergraduate major, one of the first engineering-emphasis degrees devoted to computer graphics. He was also the Founding Director of the Center for Human Modeling and Simulation (HMS), which under his leadership became internationally recognized for its groundbreaking work on virtual humans, embodied agents and simulation technologies that have impacted industries from animation and gaming to military training and human–computer interaction.
Badler leaves behind a profound legacy in the fields of computer graphics, human modeling and artificial intelligence. His research helped define how computers could simulate realistic human motion and behavior, making him a seminal figure in the evolution of computer animation and interactive virtual environments. His work laid the foundation for many of the technologies we now take for granted in visual computing.
Beyond his research, Badler was a dedicated teacher and advisor who mentored hundreds of undergraduate and graduate students, many of whom have gone on to careers in academia, research, and the movie visual effects and gaming industries. Throughout his career, he served as the Senior Co-Editor for the journal Graphical Models for 20 years, and also served on the editorial boards of several other journals in addition to authoring several books. He was extremely active in the Association for Computing Machinery’s Special Interest Group on Computer Graphics and Interactive Techniques (ACM SIGGRAPH). In recognition of his contributions to his field, he was named to ACM SIGGRAPH’s 2021 Academy Class, considered one of the highest honors in the field of computer graphics.
Badler’s legacy will continue through the work of his students, the ongoing impact of his research and the enduring strength of the academic programs he helped build at Penn Engineering.
