It all started with Ninni Kronberg inventing a way she could dry milk, and that invention is the basis of today’s Semper. Milk was in abundance, and by drying it into powder, one could make better use of nature’s resources. The Swedish entrepreneur doctor Axel Wenner-Gren bought the patent from Ninni Kronberg and started Svenska Mjölkprodukter AB in 1939 – what later became Semper. The first milk powder factory was started in Kimstad, Östergötland in Sweden.
