George Williams was honoured by British Queen Victoria

George Williams passed away on November 6, 1905, and was buried at Saint Paul's Cathedral. Queen Victoria recognized him. The YMCA's contributions during World War I are commemorated with a stained glass window in Westminster Abbey's nave's south corridor. The window base contains two pictures of Sir Williams. One portrait depicts him in his youth, while the other depicts him in his old age.

Dudley Forsyth conceptualized and created this window. Colin Williams, William's great-grandson, contributed to the current Abbey renovation and restoration. He also gave a little glass pane with the YMCA logo etched on it. This stained glass window was installed in the Abbey's Lady Chapel. Sir George Williams University, located in Montreal, was established by the YMCA and named for this English philanthropist. This university was later merged with Concordia University, although the former site was kept as Sir George William Campus.
