António de Sommer Champalimaud (19 March 1918 – 8 May 2004) was a distinguished Portuguese banker and industrialist, recognized as the wealthiest individual in Portugal. His fortune was built through significant involvement in sectors such as insurance, banking, iron ore extraction, and the cement industry. However, these enterprises were nationalized after the 1974 Carnation Revolution. Following a seven-year exile in Brazil, he returned to Portugal to reestablish his commercial ventures.

Biography

António was born in Lisbon as the eldest child of Carlos Montez Champalimaud, a military physician and landowner in the Douro region, and Ana de Araújo de Sommer, who descended from prominent German and French lineages. He attended La Guardia Jesuit High School and briefly pursued Chemistry at the University of Lisbon but left at age 19 to oversee the family’s construction firm after his father passed away. At 28, he inherited the influential cement company of his uncle Henrique de Araújo de Sommer, thereby broadening his industrial influence.

In 1941, António married Maria Cristina da Silva José de Mello, daughter of leading industrialist Dom Manuel Augusto José de Mello, associated with the extensive Grupo CUF conglomerate which operated in chemicals, textiles, banking, insurance, shipbuilding, shipping, and tobacco sectors. The couple had seven children before their divorce in 1957. Subsequently, António entered into direct competition with his former brother-in-law within banking and insurance industries.

Champalimaud bequeathed €500 million to create the Champalimaud Foundation, focused on promoting advancements in biomedicine. The foundation also grants an annual €1 million award recognizing pioneering work in vision science—a meaningful tribute given António’s own experience with blindness later in life.

Business

In 1946, Champalimaud expanded the cement enterprise inherited from his uncle Henrique de Sommer, achieving near-monopoly status within Portugal and extending operations into Portuguese territories such as Angola and Mozambique.

During the early 1960s, he acquired Banco Pinto & Sotto Mayor (BPSM) along with insurance companies Confiança, Mundial, and Continental Resseguros. In 1969, facing an arrest warrant related to a dispute over shares in Empresa de Cimentos de Leiria, he fled to Mexico. The warrant was lifted in 1973, enabling his return to Portugal.

After the 1975 Carnation Revolution, his businesses were nationalized. Champalimaud then moved first to France and later Brazil, where he rebuilt his fortune by founding a cement firm and managing agricultural estates. Upon returning to Portugal in 1992, he began reacquiring his previous enterprises.

Ultimately, Champalimaud sold the Champalimaud Group to Banco Santander Central Hispano (BSCH), Spain’s largest banking institution.
