The stained glass in Liverpool Cathedral all dates from the 20th century. The designs were planned by a committee working in conjunction with the architect of the cathedral, Giles Gilbert Scott, with the intention of forming an integrated scheme throughout the cathedral. A number of stained glass designers were involved in the scheme, but the major contributors came from James Powell and Sons (Whitefriars Glass), in particular J. W. Brown, James Hogan, and Carl Edwards.
