William Herschel [SEP] Memorial
William Herschel lived most of his life in the town of Slough, then in Buckinghamshire (now in Berkshire). He died in the town and was buried under the tower of the Church of St Laurence, Upton-cum-Chalvey, near Slough. Herschel is especially honoured in Slough and there are several memorials to him and his discoveries. In 2011 a new bus station, the design of which was inspired by the infrared experiment of William Herschel, was built in the centre of Slough. His house at 19 New King Street in Bath, Somerset, where he made many telescopes and first observed Uranus, is now home to the Herschel Museum of Astronomy.
