Williams gave generously to those in need. He was especially linked with the Jimmy Fund of the Dana–Farber Cancer Institute, which provides support for children's cancer research and treatment. Williams used his celebrity to virtually launch the fund, which raised more that $750 million between 1948 and 2010. Throughout his career, Williams made countless bedside visits to children being treated for cancer, which Williams insisted go unreported. Often parents of sick children would learn at check-out time that "Mr. Williams has taken care of your bill." The Fund recently stated that, "Williams would travel everywhere and anywhere, no strings or paychecks attached, to support the cause ... His name is synonymous with our battle against all forms of cancer."
