Constable John Knight joined Hertfordshire Constabulary on the 27th day of November 1889 and served until the 26th March 1919.
The picture in which he is seated was taken on or about his retirement.
In 1911, Constable Knight was one of 13 officers in the Constabulary to receive the King’s Coronation Medal.
He can be seen standing second from the left with other recipients of the medal, believed to have been taken in market stalls in Watford.
In the larger group photograph, he can be seen sitting on the far left, with Superintendent Frogley sitting front and centre.
Knight’s grandson, PC 569 Godfrey GALE and great grandson, PC 540 Clive GALE, also served in the Constabulary.
