William Edgeworth

William Edgeworth's practical interests initially followed those of his father, such as surveying; he moved into cartography.

[4][5] Edgeworth's surveying work in Ireland included soundings in the River Inny and the mapping of bogs.

[12] Unlike some other surveyors in Ireland at the time, he encountered little opposition to his work; he took a tactful and communicative line with local people.

[1][18] He carried out an early railway survey of 1828 in Ulster (Armagh to Newry), done in fact two years before that.

[23] Charles Babbage wrote, as illustration of economic doctrine, about a "money pump" devised by Edgeworth.
