Bindon Blood Stoney
Bindon Blood Stoney was a pioneer in Irish Engineering and also made advances in astronomy.

Achievements
Stoney has a long list of accomplishments that are difficult to put into words. Stoney attended Trinity College Dublin and earned a Civil Engineering Diploma. In 1904 Stoney was elected FRS and received an honorary LL.D. from the University of Dublin the same year. In 1857, he was elected to the Royal Irish Academy. In 1870, he served as President of the Institution of Civil Engineers. Stoney made significant advances in astronomy and architecture. He detected 105 NGC objects and 8 IC objects while mapping the spiral pattern of the Andromeda Galaxy. All IC objects and 91 NGC objects were brand new. This alone was a notable achievement. Under James Barton, Stoney was Resident Engineer of the Boyne Viaduct in 1853. When it was built in 1857, this viaduct had the world's longest span and was one of the pioneers in using metal girders of any size. This experiment eventually inspired Stoney to publish Theory of Strains in Girders and Similar Structures, a famous work that provided practical recommendations for calculating the strains that occur in girders and became an everyday reference for structural designers.

He designed a massive dredging operation and rebuilt the quay walls on the River Liffey both north and south banks, replacing tidal docks with deepwater facilities. He constructed the Alexandra Basin by extending the northern quays eastward. He constructed the lower areas of the deep water quay walls with massive concrete blocks weighing up to 350 tons to avoid costly dams and pumps. Stoney built the gear for moving these massive blocks, as well as the gigantic diving bell used to prepare the foundations. Stoney also excavated a new 70-acre basin with an average depth of around 11.5 metres while working on the North Wall Extension. The largest ships were able to dock as a result of this. Bindon Stoney utilised the same procedures at the Poolbeg Lighthouse between 1875 and 1877, laying massive monolithic blocks weighing roughly a hundred tons at the base to defend it from winter storms. He designed the Grattan Bridge the O'Connell Bridge, Butt Bridge. Drogheda, Arklow, Bray, Ballina, Wexford, Queenstown, Kilmore, Cork, Wicklow, Galway, Westport, and Sligo all had him as a consulting engineer.
