Benjamin Hall Blyth

In 1848 he established an engineering practice on the prestigious George Street (at no 124) in Edinburgh where it would remain for the next 100 years.

The practice did work for the Caledonian, Glasgow and South Western, Scottish Central, Dundee and Perth, Great North of Scotland and Portpatrick railway companies.

[7] Blyth died from diabetes[8] aggravated by overwork at home in North Berwick on 21 August 1866 and is buried in the Grange Cemetery, being survived by his wife, seven sons and two daughters.

[10] His house served as the offices of Scottish Natural Heritage between 1950 and 2003 then reverted to its use as a family home.

[11] The harbour engineer, William Dyce Cay, worked under Blyth on the Castle Douglas to Portpatrick Railway in 1861.
