JASON RIGBY was born in Dublin on the 24th July, 1846. He entered Trinity College in 1864, and in due course graduated in Arts and obtained the licence in Engineering.
In 1871-2 he was assistant to Mr. Tait, County Surveyor of Antrim, and had sole charge of a district.
In 1872 he sailed for Brazil, and was employed as first assistant on the Parana. and Matto Grosso railway surveys under the late Captain C. Palm and afterwards under the late Mr. William Lloyd. Whilst engaged on this work he penetrated with his companions into parts of Brazil previously unexplored, and, with possibly one exception, is known to have been the last survivor of this expedition.
In 1875 he married Miss Anne Alice Andrews of Hampstead.
In 1876 he returned to Brazil on behalf of Sir Charles Fox and Sons to survey the construction of the Imperial Brazilian Natal and Nova Cruz line in Rio Grande do Norte, and from September, 1878, he had charge of the construction of that railway until his appointment in I883 as Resident Engineer for Messrs. Sir Douglas Fox and Partners. As soon as the line was completed the Board invited him to become General Manager and Chief Engineer, a position he held until 1885.
The late Mr. Frank Parish, who was Chairman of the Great Western of Brazil Railway Company, then offered him the Managership of that line, an appointment which he held until 1891, residing in Pernambuco, where yellow fever was very prevalent in those days.
In 1894, again at the invitation of Mr. Frank Parish, he became General Manager of the Buenos Ayres and Rosario Railway, since merged into the Central Argentine Railway. He held this position until 1899, when he came home to accept a seat on the Board of that Company. In the same year he became a Director of the Buenos Ayres Great Southern Railway Company, and on the death of Mr. Frank Parish in 1906, he was elected Chairman of that Company.
At the time of his death Mr. Rigby was a Director of a number of railway companies in South America. He died suddenly at his residence, Holmleigh, Putney Hill, on the 9th September, 1910, aged 64.
Mr. Rigby was elected an Associate of The Institution on the 1st February, 1876, was subsequently placed in the class of Associate Members, and was transferred to the class of Members on the 13th March, 1883.
