W. G. R. Sprague

William George Robert Sprague (1865 – 4 December 1933) was a theatre architect. He was apprenticed to the well-known practitioner of that profession, Frank Matcham, and later established his own practice, designing at least thirty-five theatres between 1890 and 1929. Of his surviving London theatres, eleven are Listed – officially designated as of particular architectural or historic interest deserving special protection. Ten are listed in the basic category, Grade II, and one – Wyndham's is in the middle category, Grade II*.

The two substantially intact Sprague theatres outside London are the Lyceum, Sheffield, which is Grade II* Listed, and the Théâtre Édouard VII, Paris, designated a Monument historique.
