Grant Sanderson

Grant Sanderson is an American math educator, animator, and content creator best known as the founder and voice behind the widely acclaimed educational YouTube channel 3Blue1Brown. Born in the United States, Sanderson gained international recognition for his distinct visual approach to teaching higher mathematics, physics, and computer science. By combining computer animations with intuitive storytelling, he has transformed complex topics like linear algebra, multivariable calculus, probability, and artificial neural networks into visually engaging and accessible lessons for millions of viewers worldwide.

Early Life and Education

Sanderson developed a strong passion for mathematics and programming during his youth. He attended Stanford University, where he pursued undergraduate studies in mathematics and computer science, graduating with a bachelor's degree in 2015. While wrapping up his degree at Stanford, he began experimenting with programmatic animations to visualize mathematical concepts, laying the foundation for his future creative endeavors. After completing his degree, he joined Khan Academy as a content fellow from 2015 to 2016, producing comprehensive instructional videos and articles focused primarily on multivariable calculus.

3Blue1Brown and Manim

In late 2016, Sanderson transitioned to working full-time on his personal project, 3Blue1Brown. The channel's unique name and logo are derived from sectoral heterochromia in his right eye, which is three-quarters blue and one-quarter brown. To produce the custom animations for his videos, Sanderson created Manim (Mathematical Animation Engine), a Python-based open-source visualization library. Manim allows creators to programmatically generate precise, high-quality mathematical animations and has grown into a popular tool widely utilized by STEM educators, researchers, and animators around the globe.

Academic Contributions and Outreach

Beyond his main YouTube channel, Sanderson has actively contributed to broader mathematical outreach and university education. In 2020, he collaborated with faculty at the Massachusetts Institute of Technology to help design and lecture for the course "Introduction to Computational Thinking." He has also delivered public lectures at prominent institutions like Stanford University and Harvey Mudd College, collaborated on science documentaries such as Netflix's "A Trip to Infinity," and launched the Summer of Math Exposition, an annual community competition designed to foster and highlight independent online math communication.
