Carl Gustaf Patrik de Laval (1845 - 1913) was a Swedish engineer and inventor who made important contributions to the design of steam turbines and dairy machinery. In 1887 he built a small steam turbine turned by jets of steam, and in 1890 added a nozzle to increase the speed of the steam entering the turbine. De Laval's innovations are used today in rocket design and reduction gearing.
