The historic quarries expanded as demand for stone,
gravel and clay grew throughout the century. New industries began
to move to Peterborough, building their factories on the green
fields around the city. Baker Perkins and Peter Brotherhood, both
manufacturers of industrial machinery, became major employers, and
local manufacturing companies developed and grew. The two World
Wars brought many changes to the inhabitants of the Peterborough
area. Those who fought and died in the Great War were
commemorated by the building of a new hospital. Edith Cavell, who
had been a pupil-teacher at Laurel Court School in the city, is
also commemorated - she was executed by the Germans in 1915 for
aiding the escape of resistance fighters from Belgium.
The flat, open countryside around Peterborough made
an ideal location for airfields. RAF Wittering was established as a
Home Defence Force airfield during the First World War. During the
Second World War, the enlarged airfield was home to night fighters,
and the station remains important today as the home of the RAF's
famous 'Harrier' jets. Throughout the Second World War, pilots were
trained at RAF Peterborough (or Westwood), established on the
outskirts of the city during the 1930s. There were many other
wartime airfields locally, some home to United States Army Air
Force units.
After the First World War, Peterborough City Council began
building 'homes fit for heroes' - council housing for working
people, which increased growth in the city.
Throughout the 20th century the city expanded to
incorporate many places such as Walton, Newark and Fletton, which
had formerly been entirely separate villages. Then, in the late
1960s, Peterborough was designated as a site for a new town, which
would grow around the historic city centre. From the beginning of
the 1970s, many new housing areas were developed, including Bretton
and Ravensthorpe. New, service-based companies like Thomas Cook and
Pearl Assurance were now attracted to the city, ending the
dominance of the manufacturing industry as main employers.
Labour shortages after the Second World War encouraged people
from across the world to move to Britain in search of employment.
People from throughout the British Isles, Italy, India, Pakistan,
Poland and the Caribbean came to Peterborough to work in the brick
and engineering industries. The area's rich cultural diversity
continues to develop as people move into today's growing city and
villages.
