Please answer the following question: Found the following article online, use it to answer the question: What is the full name of the person that joined William Burges's office in the 1850's?  Almost his sole champion in the years after his death was his brother-in-law, Richard Popplewell Pullan. Primarily an illustrator, as well as a scholar and archaeologist, Pullan trained with Alfred Waterhouse in Manchester, before joining Burges's office in the 1850s. In 1859, he married Burges's sister. Following Burges's death in 1881, Pullan lived at The Tower House and published collections of Burges's designs, including Architectural Designs of William Burges (1883) and The House of William Burges (1886). In his preface to Architectural Designs Pullan expressed the hope that illustrated volumes of his brother-in-law's work "would be warmly welcomed and thoroughly appreciated, not only by his professional brethern, but by all men of educated taste in Europe and America." This hope was not to be fulfilled for a hundred years but Burges's work did continue to attract followers in Japan. Josiah Conder studied under him, and, through Conder's influence, the notable Japanese architect Tatsuno Kingo was articled to Burges in the year before the latter's death. Burges also received brief, but largely favourable, attention in Muthesius's Das Englische Haus, where Muthesius described him as "the most talented Gothicist of his day". From the later twentieth century to the present a renaissance has occurred in the study of Victorian art, architecture and design and Crook contends that Burges's place at the centre of that world, as "a wide-ranging scholar, an intrepid traveller, a coruscating lecturer, a brilliant decorative designer and an architect of genius," is again appreciated. Crook writes further that, in a career of only some twenty years, he became "the most brilliant architect-designer of his generation," and, beyond architecture, his achievements in metalwork, jewellery, furniture and stained glass place him as Pugin's only "rival [.] as the greatest art-architect of the Gothic Revival."
