About Erik Cassel

Lived 1967 – 2013 (aged 45). Erik Cassel was an American computer scientist and businessperson.

Erik Stefan Cassel (December 16, 1967 – February 11, 2013) was an American entrepreneur, engineer, and software developer. He was best known as the co-founder of Roblox Corporation, alongside David Baszucki, and served as the company's chief scientist. Cassel was involved in the development of Roblox from its earliest prototypes until his death in 2013.

Early life and education

Erik Stefan Cassel was born on December 16, 1967, in the United States to David and Edith Cassel. In a 2010 interview, he recalled being introduced to computers by his father at a young age. He later began programming on a TRS-80 computer while in junior high school, writing games during school recess. He attended Ithaca High School (Ithaca, New York), graduating in 1985. He received the S. Carolyn Marsh Award for Senior Orchestra. He was a member of Boy Scouts of America Troop 19 for seven years and received the Eagle Scout Award, the organization's highest rank.

Cassel attended Cornell University and studied physics. As a student, he developed the first data analysis software used in Cornell's introductory physics laboratory experiments and completed a course project that combined physics and computer graphics. He also spent a year in Germany as part of a student exchange program.

Knowledge Revolution developed educational and engineering simulation software, including Interactive Physics. In December 1998, the company was acquired by MSC Software for $20 million. Baszucki and Cassel subsequently held senior positions at MSC Software before leaving the company and beginning work on what would become Roblox.

Roblox

In the early 2000s, Cassel and Baszucki began developing an early prototype of Roblox. The project was initially known as "eBlocks" and later "DynaBlocks" before being renamed Roblox. The two worked together from an office in Menlo Park, California, developing the early versions of the platform.

Roblox was formally released on September 1, 2006.

Cassel's interests outside of programming included cooking, bicycling, playing the violin, ultimate Frisbee, and woodworking.

The post also included tributes from several of Cassel's colleagues. Keith Lucas, who had worked with Cassel at Knowledge Revolution since 1997, credited him with teaching him how to approach engineering through iteration and experimentation and highlighted his role in building much of Roblox's original web infrastructure. Matt Dusek remembered Cassel for his intellect, generosity, engineering ability, humor, work ethic, and ability to inspire those around him. Tim Loduha recalled his kindness, humility, and willingness to help and teach others, while John Shedletsky described him as generous with his time and knowledge and praised his technical ability and character.

A Memorial Place was also created by Cassel's sons in his memory. Roblox promoted the memorial as a way for the community to honor Cassel, his family, and his contributions to the platform.

Cornell University established the Erik Cassel '90 Prize in his memory. The award is given to an undergraduate physics major who demonstrates exceptional creativity and promise in applying computer programming to a project in physics or a related field. Cornell states that Cassel's family provided funding for the award.

Roblox toy

In 2017, Roblox released a collectible figure based on Cassel's Roblox avatar as part of its first series of Roblox toys; the figure included a code for the virtual accessory "Erik's Code Review Specs".

Foundation

The Erik S. Cassel Foundation was established in his memory. The foundation's officers and directors have included members of Cassel's family.
