William O'Ryan (born in 1852) was trained as a surveyor and engineer. In addition to practising his profession in Poverty Bay, he also took up bridge building contracts. In 1886, he built the wooden approach to the Gisborne breakwater. For 16 years he was engineer to Waiapu County, and, during much of that time, he was also county clerk. A good deal of the road and bridge work carried out under his supervision was badly damaged by floods between 1916 and 1918. He died at Auckland on 2 October 1939.
