Ruben Rausing

Sweden, packaging. Rausing co-founded the packaging firm Åkerlund & Rausing in Malmö and in 1951 set up Tetra Pak to make a tetrahedral paper carton for milk. Its later aseptic cartons let milk and juice keep for months without refrigeration, which made it valuable in hot countries without cold chains. Tetra Pak sold packaging machines and the cartons they used, a model that spread worldwide. He died in 1983.
