Landscape designer to the Metropolitan Board of Works. He wrote 'Parks, Open Spaces and Thoroughfares of London' (1869). Was the first Superintendent of Alexandra Palace Park, and was also bailiff of Epping Forest and Burnham Beeches.
Born Scotland. Moved to London in 1851 and working at the Royal Botanical Gardens and on land belonging to the King of Belgium (we wonder where this was).
A member of the Honourable Artillery Company, rising to the rank of Major.
1863 appointed superintendent of Alexandra Palace and Park, and then became the superintendent of open spaces owned by the Metropolitan Board of Works, giving him responsibility for Finsbury Park, Southwark Park, Victoria Embankment, Albert Embankment, Hampstead Heath, Blackheath, Shepherd's Bush, Stepney Green, Hackney Commons and London Fields. To which we can add Victoria Park, Queen's Park and Queen Mary's steps.
From 1879 he was Superintendent of Epping Forest, through until his death, when his son, Frank Fuller McKenzie, took over.
Most of this information comes from the excellent AIM25 page on McKenzie.
