In 1922, Holderbank, as the company was then known, expanded beyond the Swiss borders into France. Schmidheiny continued to expand, primarily by buying stakes in existing companies. By the end of the decade Holderbank held stakes in Belgium, Germany, the Netherlands, and Egypt. Positions in Lebanon and South Africa soon followed. Schmidheiny died in the 1930s and his sons, Ernst Jr. and Max, took over the business, splitting it into two divisions. Ernst took over the Holderbank building materials business, while Max oversaw the other lines. This organization scheme remained in place until the 1970s.
