Bindon Blood Stoney (1828-1909), F.R.S., made his reputation first as
an astronomer by discovering the spiral character of the great nebula
in Andromeda. Turning to engineering, he was responsible for the
construction of many important works, especially in connection with
the port of Dublin. He was brother of G. J. Stoney.
Sir Charles Parsons (b. 1854), F.R.S., fourth son of the third Earl
of Rosse, is the engineer who developed the steam turbine system and
made it suitable for the generation of electricity, and for the
propulsion of war and mercantile vessels. If he has revolutionized
traffic on the water, so on the land has John Boyd Dunlop (still
living), who discovered the pneumatic tire with such wide-spread
results for motorcars, bicycles, and such means of locomotion.
