Ramsey, William de
Ramsey is of great importance in the evolution of the Perpendicular style of Gothic, for surviving illustrations and fragments of masonry suggest that the chapter-house at St Paul's (destroyed) was in that style, which first emerged there and at St Stephen's Chapel, Westminster. He was therefore probably one of the inventors of that style, and, if so, he was one of the most influential architects England ever produced.
