Gustaf de Laval was born at Orsa in Dalarna. He enrolled at the Institute of Technology in Stockholm (later the Royal Institute of Technology) in 1863, receiving a degree in mechanical engineering in 1866, after which he matriculated at Uppsala University in 1867, completing a doctorate in chemistry in 1872.

In 1887 he built a small steam turbine to demonstrate that such devices could be constructed on a that scale, and in 1890 developed a nozzle to increase the speed of the steam entering the turbine. This is now known as a de Laval nozzle and is of great importance in rocket design. The high rotational speeds that de Laval's turbines were reaching demanded that he also design new approaches to reduction gearing, which are still in use today. 1887 (MDCCCLXXXVII) is a common year starting on Saturday (click on link for calendar) of the Gregorian calendar or a common year starting on Monday of the Julian calendar. ... 1890 (MDCCCXC) was a common year starting on Wednesday (see link for calendar) of the Gregorian calendar (or a common year starting on Friday of the Julian calendar). ...

De Laval also made important contributions to the dairy industry, including the first centrifugal milk-cream separator and early milking machines, the first of which he patented in 1894. It was not until after his death, however, that the company he founded marketed the first commercially practical milking machine, in 1918. Together with Oscar Lamm, de Laval founded the company Alfa Laval in 1883, which was known as AB Separator until 1963 when the present name was introduced.

In 1991, Alfa Laval Agri, a company producing dairy and farming machinery was split from Alfa Laval when it was bought by the Tetra Pak Group.
