André Oscar Wallenberg

Career As a banker, Wallenberg was a pioneer in Europe. Already during his stay in the United States in 1837, when the Panic of 1837 occurred, he had the desire to become a banker when he "learned how banks should not be run". In Stockholm in 1852, Wallenberg sought to form a branch, but received "no sanction" due to the Sveriges Riksbank's proximity. A few years later, Wallenberg participated in the establishment of branches in Sundsvall and Hudiksvall and became Sundsvallsbanken's first manager. In 1856 he formed Stockholms Enskilda Bank; the capital, 1 billion, was fully subscribed in two days. Until his death, Wallenberg was the CEO of this bank.

In the municipal life of the capital, Wallenberg played a particularly significant role. He served in the Stockholm City Council from the introduction of this institution to his death and in 1876–1877 as its deputy chairman and for a number of years as a member of the Drafting Committee .

Wallenberg married in 1846 to Catharina Wilhelmina ("Mina") Andersson (1826–1855), with whom he had four children; the daughter Oscara (1847–1863), the sons Jacob (1851–1872), Knut Agathon (1853–1938), and Wilhelm (1855–1910).

After Mina's death, he lived with her sister Lovisa Andersson from 1855 to 1861.

Wallenberg married in 1861 to Anna Eleonora Charlotta von Sydow (1838–1910), the daughter of Rear Admiral and his wife Eleonora Juliana Wiggman. They had 14 children; the sons Gustaf (1863–1937), Marcus (1864–1943), Louis (1867–1869), (1872–1939), (1874–1963), Victor (1875–1970), and the daughters Mrs. Anna Bergenstråhle (1865–1950), Countess Siri Oxenstierna (1868–1929), Mrs. Ingeborg Qvarnström (1870–1929), Mrs. Lilly Crafoord (1873–1956), Baroness Alfhild af Ugglas (1877–1952), Oscara (1878–1880), Baroness Ruth von Essén (1880–1972), and Thyra (born and died 1884).
