I was fortunate enough to visit the Lee Chapel a couple of years ago. The statue was created by renowned sculptor Edward Valentine and was unveiled in 1883. I have attached an interesting article that talks about how the committee was formed to commission the building of the statue, the fund raising, and the various ceremonies that took place at the unveiling. Needless to say, a great deal of effort, that took place over several years, went into the entire project.
It is a beautiful memorial. It absolutely breaks my heart to witness the disrespect that has been shown toward Lee and his family by many of the current faculty and administration. Quite simply, without Lee and the Lee family there would be no Washington and Lee University.
