Gustaf de Laval, inventor of the steam turbine, the de Laval nozzle (essential for rocket propulsion), the milk-cream separator, to mention three and maybe the most important of his 93 patents.
Already in 1894 the Hamra Farm was purchased by de Laval's company AB Separator. The farm is situated in the little valley between the community of Tumba in the west (Yes, It's where the hockey player Sven Tumba lived in the sixties), and the Tullinge Lake in the east.
Today the main purpose for the farm is development and testing of the latest systems for automatic milking of cows!
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. When Alfa Laval was sold, Alfa Laval Agri remained a part of the Tetra Pak group and was renamed DeLaval, after the company's founder.
Did you follow? Me neither! :-)
Just for fun, and nice to know is
The Google placemark for Tumba is misplaced. Tumba commuter train station is marked exactly 2,67km west and is the most significant landmark for Tumba community.
