William de Ramsey
William de Ramsey (fl. 1323 – 1349) was an English Gothic master mason and architect who worked on and probably designed the two earliest buildings of the Perpendicular style of Gothic architecture. William Ramsey is thought to have been one of the originators of the Perpendicular style which was to dominate Gothic architecture in England for three centuries "and, if so, he was one of the most influential architects England has ever produced".
