The
Domesday Book of 1086 records a community of 33 peasants. The population had risen to 100 by the late 13th century. The village remained sizeable throughout the Middle Ages and by 1801 there were 494 residents. By the time the parish was dissolved there were about 1,200 inhabitants. Trumpington's association with agriculture was extended in 1955, when the
Plant Breeding Institute (PBI) – founded in 1912 as part of the
University of Cambridge's School of Agriculture – moved to the Anstey Hall site adjoining Maris Lane in Trumpington. Here the PBI developed new plants, notably
potatoes called
Maris Piper and
Maris Peer, a
barley called
Maris Otter, and a wheat called
Maris Widgeon. These are now in use worldwide. The PBI was split up and privatised in 1987. In 1990 the PBI moved to
Colney, near
Norwich, but the reference to the Maris Lane site survives in the names of plants. Anstey Hall is a Grade I listed, former country house built within its own parkland. Once owned by writer and poet
Christopher Anstey and later by the polymath
Robert Leslie Ellis, it was leased to the PBI for many years. It is now used for weddings, parties, corporate events and meetings. The
Trumpington War Memorial was designed and carved by
Eric Gill, who also designed and carved the crocodile on the wall of the
Cavendish Laboratory. The memorial was dedicated on Sunday 11 December 1921 to commemorate 36 Trumpington men who died in the
First World War. The
Second World War claimed eight more local men; their names were added by
David Kindersley, a pupil of Gill.
Trumpington Fair In 1314, the lord of the manor, Giles of Trumpington, was given permission to hold a three-day fair on the
feast of St Peter's Chains (1 August). The feast was still held in the 19th century though it was transferred to 28–30 June, and became known for the rowdiness and drunkenness of its many visitors. It was reduced to only one day (29 June) in 1882 and was still held in the 1930s. ==Parish church==
