Frederick Preedy (1820-98) trained as an architect and was of the same generation of High Victorian Gothicists as Butterfield, Street & Burges. In the 1840s & 50s opinion was divided as to whether stained glass design should be left to the best artists, or, as Street & Burges advocated, be decided by architects. As a result Street and his contemporaries often produced their own designs, but used others to undertake manufacture. Preedy was unique in both designing and painting stained glass himself, producing some windows of high quality and amongst the finest of the High Victorian period.
