Peder Wallenberg, previously Sager, born 1935, is a businessman, architect, and co-founder of the foundation Carpe Vitam. He is the only son of Jacob Wallenberg. He was adopted by his biological father at a late age, sparking a controversy regarding the legitimacy of his claim to his fathers fortunes, following his passing. Peder Wallenberg has furthered his wealth exponentially through a series of business ventures including hotel resort ownership and management, creation of luxury living centers, stock market investments, and banking.
Peder has had eight children with three wives. The oldest son was born in 1967, and the youngest in 1997. Their names in descending order of age are: Fredrik Wallenberg, Marie Wallenberg, Peder Wallenberg, Nicholas Wallenberg, Anna Wallenberg, Peder Wallenberg Jr, Christopher Wallenberg, and Alexander Wallenberg.
Peder has been media-shy and has kept a low profile until recently, with a series of interviews and articles in Swedish news outlets such as Dagens Industri.
