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. After World War II, Hans Gygi, son of Adolf Gygi, took over leadership. He oversaw the company during the Swiss housing boom of the 1950s, and as Holderbank expanded into Canada, then throughout North and South America. The company went public in 1958 in order to raise more capital to fuel further expansion. Hydroelectric projects in Switzerland generated large concrete contracts, offsetting losses in Egypt when the country's government nationalized Holderbank's factories. During the early 1970s, growth in Brazil and Mexico improved the company's bottom line. The Schmidheiny brothers convinced shareholders that the company should consolidate holdings and merge with Schweizerischen Cement-Industrie-Gesellschaft. The combined company had annual revenue of 800 million Swiss francs and established Holderbank as one of the industry's largest companies worldwide. The oil crisis of 1973 hit the industry hard as construction demand dried up in much of the world. Strong markets in Lebanon and South Africa allowed Holderbank to weather the storm. By 1976, revenue and profits had returned to pre-crisis levels. In the late 1970s and early 1980s, Holderbank continued its expansion in Latin America and expanded into Asia and Spain for the first time. Thomas Schmidheiny took over leadership, overseeing the company as in expanded into Eastern Europe and experienced a boom in Spanish construction preceding the 1992 Summer Olympics. By 1986, Holderbank was the world's largest cement manufacturer. In the 1990s, the company consolidated its European holdings as the American market drove growth. Expansion into Eastern Europe and Russia continued. In 2001, the company changed its name from "Holderbank Financière Glaris" to Holcim (short for Holderbank ciment). Asia drove growth in the 2000s, as the company saw more than 50% of its business come from emerging markets. In 2005, Holcim purchased Aggregate Industries for US$4.1 billion, entering the United Kingdom for the first time. That year, the company also expanded into India by acquiring a stakes in The Associated Cement Companies (ACC) and Ambuja Cement Eastern. In 2008, Holcim became the largest shareholder of China's Huaxin Cement with a 40% stake. In 2009, they acquired Cemex Australia. In February 2012,
