In page James Blake (tennis):

"

Blake has a foundation called The James Blake Foundation, which "invests vital seed money at the leading-edge of science: speed up the most promising work, and shortening the time it takes to turn lab discoveries into better treatments for patients."[1][2] Since 2005, he has hosted Anthem Live!, a charity tennis exhibition and musical event in Virginia and New York City to raise money for cancer research.[3] In July 2008, Blake established the Thomas Blake, Sr. Memorial Research Fund to support cancer research at Memorial Sloan Kettering Cancer Center. The fund was named in memory of his father, who died from gastric cancer in 2004.[4] Nike and Fila, which sponsored Blake, created T-shirts for Blake's charity, the J-Block program, and proceeds went to the Cancer Research Fund.[4]
