Malcolm MacLeod

Major-General Malcolm Neynoe MacLeod, (23 May 1882 – 1 August 1969) was a senior British Army officer who served as Director General of the Ordnance Survey from 1935 to 1943. In 1935, he started the retriangulation of Great Britain, an immense task that involved erecting concrete triangulation pillars (trig points) on prominent hilltops throughout Britain. MacLeod can fairly be said to be the creator of the Ordnance Survey in its modern form.
