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.
