"I am dedicating the majority of my wealth to improving education," Lucas wrote in his pledge letter. "It is the key to the survival of the human race. We have to plan for our collective future — and the first step begins with the social, emotional, and intellectual tools we provide to our children. As humans, our greatest tool for survival is our ability to think and to adapt — as educators, storytellers, and communicators our responsibility is to continue to do so."
Lucas founded the George Lucas Educational Foundation and the website Edutopia to reform and improve K-12 education. The foundation emphasizes hands-on, project-based learning over plodding devotion to standardized tests and traditional textbooks. It highlights innovative teaching efforts that are already working in classrooms. You can read more about Lucas' efforts in a Q&A with Forbes' Luisa Kroll.
While Lucas may choose to donate the billions he made from selling Lucasfilm to a broader range of efforts, it is likely that a large portion will be distributed to this cause. And when Lucas does make that donation official, he will have placed himself into rarified company among philanthropists. Only a select few billionaires will have given away as much as he plans to. While his $4 billion won't get him as far as [Bill] Gates or [Warren] Buffett, who have donated more than $45 billion combined, Lucas is following their example and should reach the next tier of biggest givers.
