Gilbert Mackenzie Trench
Gilbert Mackenzie Trench (1885–1979) was a Scottish architect, and the Architect Surveyor to the Metropolitan Police.[2] He is credited as the designer of the iconic Police Telephone Box which has since become a pop culture icon owing to its immortalisation as the space-time machine of Doctor Who.[3] Information is sparse about him, as he is known mostly for the Police box and the Police Box alone. Little to no details exist though in the run-up to the airing of Twice Upon A Time (2017), there was some fan speculation as to whether the Captain (later revealed as the father or grandfather to the recurring character Brigadier Lethbridge-Stewart) was based on or even was Mackenzie Trench.

Early life
Gilbert Mackenzie Trench Was born to Gilbert Kennedy Campbell Trench (1855–1937) and Clementina Flett (1857–1938)[4] on April the 4th, 1885, in East Dulwich. He is known to have served in WWI, based on his medals from service.[5]
Police Box
In 1928, Trench was commissioned by the Metropolitan Police to design a new Police Box, able to not only take calls from public notifying the police force of a crime, but to also allow a "Bobby On The Beat" to sit inside and make himself a cup of tea whilst he waited for a call-out. It began its installation in 1929, with demonstrations at the 1936 Radio Show.[6] The boxes saw much use over the next 40 years, doubling as air raid sirens in WW2. By 1969, however, walkie-talkies and quick response vehicles such as the Ford Zephyr had made it redundant, and the home secretary James Callaghan had nearly all of them demolished. As of present, only 11 remain of the over 1000 originally constructed. It was immortalised in the British TV show Doctor Who after it became the disguise for the titular character's space-time machine, The TARDIS.
Later life
Trench fathered two children, Jean Doris Trench (1913–2008) and Kenneth Mackenzie Trench (1923 - 1923). He died in 1979 in Wanganui, New Zealand.[4]
