Joseph Philip Ronayne

Joseph Philip Ronayne (1822 – 7 May 1876) was an Irish civil engineer notable for his role in the development of Irish railways. A leading member of the Home Rule League, he was a Member of Parliament (MP) for Cork City from 1872 to 1876.

Ronayne, youngest son of Edmond Ronayne, a glass-maker of Cork, was born at Cork in 1822. After an education under Messrs. Porter and Hamblin at a school in Cork, and instruction from Mr. O'Neill in practical surveying, he entered the office of Sir John Benjamin McNeill, civil engineer of London and Glasgow. He was first engaged in the design and construction of the main arterial lines of railway in Ireland, and then on one half of the Cork and Bandon Railway, a work which he successfully accomplished. In 1853 he proposed furnishing Cork with water by the construction of a lake near Blarney, but this, a gravitation scheme of great simplicity, was not carried out. On 4 March 1856 he became a member of the Institution of Civil Engineers.

From 1854 to 1859 he was in California, where he superintended hydraulic works, bringing down the waters of the Sierra Nevada to the goldfields by means of canals and aqueducts. Soon after returning to Ireland he became a contractor, and executed the Queenstown branch of the Cork and Youghal railway. On the completion of that work he laid out the Cork and Macroon railway. He took payment in shares, and thus occupied the unusual position of engineer, contractor, and the largest proprietor, a combination which led to the line being designed with economy, efficiency, and careful management. He subsequently suggested to the government the construction of a dock in a bay near Monkstown, a plan looked upon with favour by some engineer officers, but the Haulbowline site was finally adopted. On 10 December 1872 he was elected in a by-election to represent Cork City in the Parliament of the United Kingdom, after the death of John Francis Maguire. He was re-elected at the 1874 general election and retained the seat until his death. Clear-sighted and of the strictest integrity, he was as much respected by his political adversaries as by his supporters.

He died at Rinn Ronain, Queenstown, on 7 May 1876, and was buried in Father Mathew's cemetery, Cork, on 11 May. He married, in 1859, Elizabeth, daughter of Edward Stace Wright, commander R.N.
