Remembering Those We’ve Lost

Remembering Steven Parker

Remembering Steven Parker

Steven Parker, vice president of professional graphics at NVIDIA Corporation and former professor in the Department of Computer Science at the University of Utah, passed away peacefully at his home in Draper, Utah, on May 2nd, 2024.

Steven Parker grew up in Oklahoma. He excelled in mathematics, but his interest in school declined when his teachers prevented him from working ahead of the standard curriculum. Yet his passion for mathematics persisted, and he taught himself about electronics and computers. Although he didn’t graduate from high school, Steven received an outstanding score on the ACT exam. He was admitted to the University of Oklahoma and completed a bachelor’s degree in electrical engineering, focusing on computer graphics.

When he discovered the University of Utah’s pioneering work in computer graphics, Steven decided to pursue his PhD there. The basis of his doctoral thesis was the SCIRun Software System, for which he was the principal architect. He was the first graduate student at the University of Utah to receive a prestigious Department of Energy Computational Science Graduate Fellowship for his design of visualization algorithms used by the Center for the Simulation of Accidental Fires and Explosions. 

After earning his PhD, Steven joined the faculty at the University of Utah, where he created the Center for Interactive Ray-Tracing and Photo Realistic Visualization. His work advanced fundamental computer graphics techniques, including ray tracing, resulting in more accurate visualizations. He and his colleagues used the university’s computational capacity to develop the first interactive ray tracing system. Previously, ray tracing could only be performed using offline rendering. For the first time, the groundbreaking system from Steven’s team enabled a user to dynamically explore scenes rendered with the photorealistic lighting effects characteristic of ray tracing. 

While at the University of Utah, he co-founded RayScale, which was acquired by NVIDIA in 2008. NVIDIA subsequently established an office in Utah, with Parker as director. “Steve came to NVIDIA to change the world of computer graphics: He wanted to make real-time ray tracing a reality, mainstream, a pillar of computer graphics. He accomplished exactly that, and so much more. He led the company and the industry into a new era,” said Dr. David Luebke, vice president of graphics research at NVIDIA.

As an expert in high-performance parallel computing, scientific computing, artificial intelligence, and computer graphics, Steven was recognized by the technical community as one of the world’s preeminent computer research scientists. He developed RTX, NVIDIA’s real-time ray tracing technology, now used in games and movies, and made meaningful contributions to the fields of physics, chemistry, and medical science.  

Steven was recognized for his work with the Honors Medal from Computer World, an honorary engineering doctorate from the University of Utah and as one of HPCWire’s People to Watch.

In addition to being a world-renowned researcher, Steven mentored the next generation of engineers and computer scientists. At a celebration of the 50th anniversary of the University of Utah’s Computer Science department, Parker offered five pieces of advice for students: keep pushing the university to be a special place; chase both depth and breadth; embrace parallelism at multiple scales; build something ambitious—bigger than yourself; and recognize you stand on the shoulders of giants.

Steven was active in his local and technical communities, serving on the board of directors for the Clark Planetarium, as a member of the Engineering National Advisory Council, on program committees for significant computer conferences and on advisory boards for the College of Engineering at the University of Utah. 

He co-led the campaign committee for the John and Marcia Price Computing and Engineering building at the University of Utah and, in 2024, was awarded a Lifetime Service Award from the Price College of Engineering at the University of Utah. 

Richard B. Brown, H. E. Thomas Presidential Endowed Dean of Price Engineering, described Parker as “one of the most talented computer science researchers in the world. His dedication to pushing the boundaries of technology resonates with the university’s vision of making a positive impact on society through education and research and aligns with the university’s ethos of innovation.”

Steven was devoted to his family and prioritized spending time and sharing his passions with his wife, children and grandchildren. He enjoyed cooking and found joy in experimenting with new recipes and sharing the gift of food with those he loved. Steven’s kitchen was a place where memories were made, and traditions were honored.

Steven is survived by his wife, MeriAnn Parker; his children, Morgan (Nathan) Mabey, Alyssa (Brian) Vance, Amber Parker, and Elena Parker; his grandchildren James Ashdown, Makayla Ashdown, Zoe Ashdown, Maximus Vance, and Amelia Vance; his parents, Jeanene Hale and Gregory Parker; his siblings, Michael (Katie) Parker, Sheryl Tatum (Bret) Bradley, Jennifer Horn, Tamara Parker, Marilyn (Alen) Howard, William (Christine) Parker, and Christopher (Christy) Parker; his parents-in-law Ronaele and Larry Freestone; his sisters-in-law, Sheri (Justin) Swart, Keri (Kenneth) Martinez, and Lori (Neil) Sood; and many aunts, uncles, nieces, nephews, and cousins.

February 26, 1963 – February 3, 2022

“Fran inspired me to challenge myself as an artist. He had such an immense impact on my life.” 

“I was a student, friend, and colleague for many years. Fran helped change my life as a young student and helped me grow as a man by setting a quiet example.”

A long time ACM SIGGRAPH volunteer and associate professor of Digital Media in the School of Communication and Multimedia Studies at Florida Atlantic University, Fran is remembered as an exceptional teacher, mentor and friend.

Upon completing both his BA and MFA from FAU, Fran joined the newly established Florida Center for Electronic Communication. As Associate Director of the CEC in 1998, he supervised all aspects of digital video production and 3D computer visualization projects. Fran’s grant funded projects included collaborations with Florida International University’s International Hurricane Research Center, the Centre for the Arts at Mizner Park, and archaeological visualization of soon to be lost ancient tombs in Sicily. His computer animated vision of clean energy technologies, under development by FAU’s Ocean Engineering department, played a key role in landing the new Center for Ocean Energy Technology.

ACM SIGGRAPH was also fortunate to have Fran as an active volunteer.  In addition to serving as the chair for the Professional and Student Chapters Committee and on the ACM SIGGRAPH Executive Committee as Director for Chapters, he was also a key leader of the Fort Lauderdale professional chapter.  Most importantly, Fran was a beloved mentor to his students and many other young people who have become important contributors to the SIGGRAPH community and the computer graphics industry.

Fran was a born teacher who worked with students from all ages and backgrounds, including junior and high school students interested in STEM, undergraduates beginning their academic journeys and graduate students he inspired as a scholar and an artist.

Fran won numerous awards and international recognition for his work, but the legacy he leaves is as an exceptional and loving husband and father, proud grandfather, calm, thoughtful and kind friend, beloved colleague and supportive teacher and mentor.

Remembering Frederick P. Brooks Jr.

Remembering Frederick P. Brooks Jr.

Fred Brooks, April 19, 1931 – November 17, 2022

It is with great sorrow that ACM SIGGRAPH marks the loss of Dr. Frederick P. Brooks, Jr., a pioneer in the field of computer science, a recipient of the ACM A.M. Turing Award, an inaugural recipient of the US National Medal of Technology, and member of the SIGGRAPH Academy.

Fred Brooks grew up in North Carolina, graduated summa cum laude in physics from Duke University, and earned his PhD in applied mathematics at Harvard University. He joined IBM upon graduation. In the broader computer science community, Brooks is best known for his role as project manager for the IBM System/360 family of computers which were notable as all, largest to smallest, could run the same software.  When the development of the Operating Systems/360 software was behind schedule, Brooks assumed management of that project.  For his work on the System/360 hardware and software, Brooks shared the first National Medal of Technology with Bob Evans and Erich Bloch. 

Brooks recorded his experiences and lessons learned on the OS/360 project in his best-known book, The Mythical Man Month: Essays in Software Engineering.  This book is a standard reference for practical software engineering and is where he coined Brooks’ Law that adding personnel to a software project that is behind schedule delays it even more.  He also coined the term computer architecture and, by choosing it for the System/360 family, he established the 8-bit byte as standard in the computing industry.

Dr. Brooks joined the University of North Carolina at Chapel Hill in 1964, where he founded the Department of Computer Science, the second free-standing CS department in the United States.  He served as department chair for 20 years and continued teaching and research for another 31 years. His research focussed on 3D interactive computer graphics, human-computer interaction, virtual reality, computer architecture, and the design process.  Brooks’ promoted the idea of computer scientists as toolsmiths, encouraging his students and colleagues to develop computer technology that could be applied to help other people solve their problems.

Dr. Brooks was honored with dozens of academic and scientific awards.  More than 40 students completed their doctorates under his supervision and he was recognized as an extraordinary role model and mentor for his academic and research colleagues and many members of the SIGGRAPH community.

Fred Brooks’ substantial contributions to the field of computer graphics and interactive techniques, the influence of that work through the development of new research and innovations, and his role as an active member of the SIGGRAPH community were recognized by his induction as a member of the SIGGRAPH Academy in 2019.

Dr. Brooks, a committed Christian, will be remembered for his humility, generosity, and kindness. The SIGGRAPH community will miss his smile and good humor, his research contributions, and his wisdom.

Note:  Dr. Brooks always used the Oxford comma because he liked that it eliminated potential ambiguity.  Even though it goes against the SIGGRAPH style guide, we have, in his honor, used the Oxford comma in this memorial.

Remembering Jackie White

Remembering Jackie White

April 22, 1949 – October 7, 2021

Mentor.  Mother.  Sister.  Grandmother.  Volunteer.  Cake decorator extraordinaire.  Award winner.  Family genealogy researcher.  We remember Jackie White for being all of these things, but most of all for leaving a tremendous legacy for her family, her community and for SIGGRAPH.

A true California girl, Jackie was born and raised in Monterey Park, California.  She attended Mission High School in San Gabriel where she was very active in the drum and bugle corps.  The oldest of 5 children, she had two younger sisters and two younger brothers and was also very close to her cousins Jim and Tommy, who were closer to her age than her 3 youngest siblings.  Jackie’s son, Chris Sawtelle, believes that Jackie thought of Jim and Tommy as brothers rather than cousins. And sadly, Jackie missed being a great-grandmother by just 2 months as her great-grandson, Marcos, was born in December 2021. 

Jackie worked in the Art Department for many years at Cal State LA, where she was honoured in 2001 with a Women of Distinction award that recognized achievements in her field, significant contributions to Cal State LA, commitment to students, commitment to women’s issues, community involvement, and professional recognition.

It was while she was at Cal State LA that her friend and colleague, Patric Prince, asked her to help with an art show she was chairing for a computer graphics organization. Little did Jackie know that this support of a friend would result in thirty years of volunteering with SIGGRAPH!

After working on the SIGGRAPH ’86 Art Show with Patric, Jackie continued as a SIGGRAPH volunteer, working on the traveling art show and, in 1989, joining the Education Committee where she was responsible for the Education Committee Newsletter.

In 1997, Scott Owen, Chair of SIGGRAPH 97, invited Jackie to chair the first conference Community Outreach program. Based on the tremendous success of including more than 1,900 local teachers and students to that program, as well as her previous contributions to the organization, the Conference Advisory Group (CAG) chose Jackie to chair the SIGGRAPH 2000 Conference in New Orleans. As part of her role as a conference chair, Jackie served on the CAG for five years, then became CAG Chair in 2005-2011 and 2012-2013, and served as CAG Chair representative to the SIGGRAPH Executive Committee in 2011-2012. She was also special sessions chair for SIGGRAPH 2002, special sessions committee member for SIGGRAPH 2003, and a member of the panels jury in 2005.

In addition to her work on the annual SIGGRAPH conference, Jackie worked tirelessly to help establish SIGGRAPH Asia and ensure its success.  In her position as CAG Chair, she ensured that the CAG and the newly formed SACAG worked together in a cooperative fashion and served in various capacities on the SACAG from initial advisor, to acting SACAG chair, and then SACAG committee member 2007-2016. She served as the EC representative to the SACAG from 2012-2016.

In 2019, Jackie was presented with the 2019 Outstanding Service Award for her long-term dedicated service to ACM SIGGRAPH.

Though her work at Cal State LA and her substantial contributions to SIGGRAPH kept her very busy, Jackie’s first love was her family.  She was truly dedicated to family genealogy research and spent hours online searching for factoids about her ancestors and identifying new ones.  She produced several books for her family that documented her research in a form they could enjoy. And when she learned that one of her ancestors was the “rackmaster” at the Tower of London, her family took her on a trip to London to visit the tower and to see the towns their ancestors had lived in. 

Jackie loved geocaching and playing Pokémon Go everywhere she went – regardless of what continent she was on. Jackie’s son, Chris, recalls that she would often ask him to slow down at intersections so she could “hop into a gym” as they went by. In Singapore in the late 2000’s, she pleasantly surprised the then-new SIGGRAPH Asia conference organizers by hauling them around their city-state to places they had never been, in search of geocaches.  Her group excursions to out-of-the-way places with the “perfect gym” at SIGGRAPH conferences became the stuff of legend.

When not hunting for GPS-based prizes, Jackie found plenty of other ways to explore the world.  Whether on safari in the jungles of Borneo, eating her way through the night markets of Hong Kong, or exploring the mountains of Kobe, Japan, Jackie made friends around the globe, and was never one to turn down an adventure. Not many people can say they had their feet nibbled at a “fish spa” with computer graphics legends Don Greenberg and Rob Cook!

No tribute to Jackie would be complete without mention of her remarkable skills as a cake decorator.  As with every project Jackie undertook, she pursued this hobby with great passion to produce extraordinary cakes for her friends and family. 

SIGGRAPH is grateful to Jackie’s family for sharing her time, talent and passion with us over her many years of contributing to so many aspects of the organization.  Jackie truly was an outstanding volunteer, mother, sister and community member and we are all lucky to have known and loved her.

Memories of Chuck Csuri

Memories of Chuck Csuri

Wayne Carlson,  SIGGRAPH Pioneer

The computer graphics world, and indeed the entire world, lost a great friend and colleague this week. Charles ‘Chuck’ Csuri passed away just months from his 100th birthday. Chuck retired from a distinguished and exemplary career at the Ohio State University, but his influence has been felt far beyond the boundaries of the campus. In the last few days I have read several postings memorializing Chuck, and many wonderful comments from former students and people from the multiple disciplines that he touched with his contributions.

I was fortunate to work with him for nearly 20 years, first as a graduate student in his lab, then as a VP at his commercial computer graphics company, and ultimately as his successor in the academic program and research facility that he created. His mentorship defined my own academic career in computer graphics, and I am forever grateful to him.

Chuck was born in 1922 on the 4th of July in West Virginia and was always proud of his Hungarian roots. He graduated from Fine Arts at Ohio State, where a friend and classmate, and later fellow faculty member, was Roy Lichtenstein.

Chuck’s choice to attend Ohio State is interesting in its own right. In his own words, he was “a skinny kid that was growing into a bigger body” and was a pretty good football player at Cleveland West Tech. An assistant coach at OSU was friends of his high school coach at Tech, and saw him play. He convinced Chuck that he might be able to be successful playing for the Buckeyes while he pursued his art degree. He ended up as a three-year letterman at tackle, playing for legendary coach Paul Brown, played on the school’s first national championship team in 1942, and earned All American and MVP honors. The following year he was selected in the 1944 NFL Draft by the Chicago Cardinals, but instead of playing in the NFL he served the next three years in the Army, and fought in the 1944 Battle of the Bulge in WWII.

When he returned to the states, the Army assigned him to an engineering school for training, and his interest in combining the aesthetics of art with issues in the world of engineering was piqued. This interest in interdisciplinary relations permeated his career from that point on. He got his graduate degree in Art and joined the faculty, and became interested in how he could use the computer to realize his visions from the first time he was introduced to this emerging technology. In the early 1960s he began experimenting in this realm and in his words, was “hooked”.

In the late 1960s, Chuck created the Computer Graphics Research Group (CGRG) using funding from a grant from the National Science Foundation. This funding, and subsequent grants, allowed him to create amazing images over the following years, including a computer generated movie, “Hummingbird”, now in the permanent collection of the Museum of Modern Art. One of his early pieces, “Random War”, was influenced by his experiences in the Army, and depicts the idiocy and randomness of death in battle.

The makeup of the members of CGRG matched his desire to put people from diverse disciplines together to advance his vision of creating artistic artifacts with the aid of the computer. Mathematicians worked with designers, with statisticians and engineers, and with artists and computer scientists. This interdisciplinary interaction brought us together. I had earned degrees in theoretical mathematics, but had become enamored with the things that a computer could bring to the discipline, so I headed to Ohio State from my home state of Idaho to do a PhD in computer science. One evening I attended a lecture by an artist who was using the computer as an artistic tool. I stayed after and talked for the next hour with that artist, Chuck Csuri.

I got a call not long after that from one of Chuck’s students. Chuck was looking for a mathematician to help with a grant that he had received from the Air Force Office of Scientific Research that provided funding to develop software to visualize the stresses on the wings of Air Force fighters at high speeds, and he remembered our conversation. Our relationship began with that call, and I soon joined his lab.

The next five years saw my fellow graduate students in the lab pushing the boundaries of cgi and computer animation. We developed software and hardware solutions and published our results, all in the progressive environment of interdisciplinary study fostered by Chuck as the director of the lab. It wasn’t always easy… Chuck might come into the lab in the morning saying “I want to be able to render artistic smoke clouds” or “I would like to see galaxies interact with each other, represented by millions of stars in each”. We’d look at our PDP 11-45 computer and swallow hard, but we would find a way to do it. It was Chuck’s energetic desire to push the limits that drove our contributions to the discipline.

Chuck had a way of quietly connecting with other researchers and labs across the country, and indeed, around the world. I don’t know how he did it, but he found a way to set aside enough cash to support every member of the lab to attend the SIGGRAPH conference every year. We would learn so much from the technical sessions, but the real advantage was meeting well into the night with other researchers, exchanging ideas and video tapes, and generating immeasurable energy that would impact us the entire year until the next conference.

In 1981 Chuck realized a personal goal of obtaining funding to take what we did in the lab to create a commercial computer animation company, and he asked me to join in that venture. Cranston/Csuri Productions created commercial animation for various clients over the next almost seven years. The necessary environment with artists and technologists working together in a company of this type was a natural extension of what we did in Chuck’s lab, and greatly contributed to the company’s success.

The company was co-located with CGRG in offices on the edge of campus, and the symbiotic relationship benefitted both organizations. Staying engaged with the University, Chuck succeeded in finally creating a formal academic program in computer graphics and computer art. Called the Advanced Computing Center in the Arts and Design, or ACCAD, it has become one of the premiere graduate programs in the country. I was honored to be chosen to succeed Chuck as the director of the program when he “retired” in 1990. We were able to acquire permanent funding that provided space in the lab and personnel to assist Chuck in the continuation of his creative ventures, which he did until his death.

Throughout his years at the University, Chuck navigated the politics within the University and the skepticism of the kind of cross-disciplinary environments that defined his activities. He eventually convinced faculty and administrators of the value of his vision, and in 2000 achieved the highest recognition of all of his various accomplishments. He received the Ohio Governor’s Award for the Arts, and Ohio State’s Joseph Sullivant Medal in acknowledgment of his lifetime achievements in the fields of digital art and computer animation. In 2006, ACM-SIGGRAPH arranged a retrospective of his career’s work titled Beyond Boundaries, and in 2011 they bestowed upon him the Award for Lifetime Achievement in Digital Art. Beyond Boundaries then travelled to different art museums and sites around the world. In 2014, he received the Distinguished Alumni Achievement Award from the Ohio State University College of Arts and Sciences.

I know many of his students and colleagues that benefited from his energy and insight that are currently in universities, cgi labs, and companies around the world will remember Chuck Csuri forever. He was preceded in death in 2019 by his artist wife of 70 years, Lee, who he always referred to as his best friend, and his son Steven in 2018. His daughter Caroline and his two granddaughters Hannah and Emily Reagh continue to contribute to his legacy. A memorial statement from Ohio State indicates that donations and gifts in Chuck’s name are requested to be directed to his favorite charity, the Special Olympics. His website https://www.charlescsuri.com and instagram account https://instagram.com/charlescsuri will remain active, and condolences can be left at either.
