Task: Question Answering
Input (English): Passage: Burges played an important role in the renaissance of High Victorian stained glass. The provision of glass of appropriate colour and richness was central to many of his decorative themes, and he invested effort in working with the best cartoonists and manufacturers to achieve this. He also studied the history of glass production, writing in his second Art Applied to Industry lecture, "[a] use of antiquarian studies is to restore disused arts, and to get all the good we can out of them for our own improvement." In the catalogue to the exhibition of stained glass cartoons from Cardiff Castle, Sargent pays tribute to "his deep knowledge of the history and techniques of glass manufacture" and Lawrence considers him a pioneer who, by his "painstaking studies, re-established the principles of medieval decoration and used this to make [his] own bold and original statements."
The results were outstanding; Lawrence wrote that Burges designed with "a vibrancy, an intensity and a brilliance which no other glass maker could match." He acknowledges Burges's debt to the manufacturers and craftsmen with whom he worked, in particular, Gualbert Saunders, whose "technique [gave] Burges's glass its most distinctive characteristic, namely the flesh colour. This is unique, had no precedents and has had no imitators." As well as at Saint Fin Barre's, Burges designed stained glass for all of his own significant churches, for reconstructions of medieval churches undertaken by others, and for his secular buildings. He undertook significant work at Waltham Abbey with Edward Burne-Jones, but much of his work there was destroyed in the Blitz. Crook writes, "At Waltham, Burges does not copy. He meets the Middle Ages as an equal.". 
Question: What is the last name of the person who designed stained glass for his secular buildings?
Output (English): Burges.
