Louis Harper

Louis Harper (23 April 1868[1] – 26 January 1940) was a civil engineer from the north-east of Scotland who designed a number of suspension footbridges towards the end of the 19th century.

[4] His father came from Turriff in Aberdeenshire, and worked as a fencer in Edinburgh and Glasgow before starting the family firm in Aberdeen in 1856, which became Harpers Ltd in 1885.

John Harper patented a mechanism for straining wire, used both to make fences and later also for the cables of bridges.

[2] Louis set up his own firm in 1889, later collaborating with the contractors James Abernethy & Co.

In addition to his bridge projects, he assisted Aberdeen Council in surveying their town water scheme.
