John Berry, CBE DL FRSE (5 August 1907 – 19 February 2002) was a Scottish zoologist and ecologist.
During this same period he was commissioned by the Scottish Hydro-Electricity Board to design the Pitlochry fish ladder to allow migrating salmon to circumnavigate the large dam built there.
This included viewing galleries for the public as it was realised this strange feature had strong value as a visitor attraction.
In October 1948 he represented the UK at the conference establishing the International Union for Conservation of Nature at Fontainbleau in France.
Berry was established as Head of Nature Conservation in Scotland immediately thereafter, prior to the legal implementation of the National Parks and Access to the Countryside Act the next year.
