Amersham is widely known because of a multinational pharamaceutical company, Amersham plc (formerly known as Nycomed-Amersham), that took its name from the town. Records of Amersham date back to pre-Saxon times, when it was known as Agmodesham, and by the time that the Domesday book was written at around 1086 it became known as Elmodesham. The Domesday entry is as follows:
Amersham is linked to London by the Metropolitan Line of London Underground, and is now the last station on its branch of this line. Much of this line is shared with the mainline railway service, which runs from Marylebone to Aylesbury.
Amersham is in two parts: Amersham on the Hill, which is close to the railway station, and Old Amersham, which contains St. Mary's, a delightful 13th century church, and several old inns.
Secondary schools in the town include Dr Challoner's Grammar School (a grammar school as the name suggests) and the Amersham School (a secondary modern).
