Asea

"At the turn between the 1960s and 1970s, Asea, L.M. Ericsson, Volvo, Skånska Cementgjuteriet, and Rederi AB Nordstjernan were the five largest companies in Sweden. In Hermansson’s book, the fifteen original families were named Wallenberg, Söderberg, Wehtje, Johnson, Bonnier, Kempe, Klingspor, Jeansson, Dunker, Broström, Schwartz, Hammarskiöld, Jacobsson, Åselius, and Throne-Holst."

"The sons were named Ragnar and Torsten, and at the next generational shift, the two began building an investment company with a broad focus, where the wholesale business became one of the assets. They foresightedly bought shares in companies that were part of the growing Swedish basic industry, such as the mining company Gränges and the forestry company Holmen, but also refining businesses such as Bulten, which still produces bolts for the automotive industry today, the electrical engineering company Asea (ABB), and Sweden’s lithographic printing company, which later became Esselte. The new investment company was named Ratos, built from the first letters of Ragnar and Torsten’s names. In 1954, the company was listed on the stock exchange; this was a way to allow individual family members to sell shares without affecting the business. The family secured control by forming the Söderberg foundations, with 27.1 percent of the votes in the company. An additional 46.4 percent was still owned by the family in 2012."
