Baldur Fridtjof was born on December 30, 1817, in Egersund, Rogaland, Norway. He was the second child of Hans Leyerdahl Nansen (b. 1764) and Vendelia Christiane Louise Møller (b. 1790).
According to Wikipedia, Baldur Fridtjof Nansen was “a lawyer without ambitions for public life”, who worked as a clerk to the Supreme Court of Norway. Furthermore, according to NRK, Baldur ran a small firm mainly dealing with property and wealth administration.
In February 1854, Baldur married Minna Sørenssen (b.1829). In December that same year, they had their only child, Hans Moltke Nansen. Minna died just six days after delivering the child, leaving Baldur a widower.
In 1858 Baldur married one of his clients, the widow Adelaide Bølling (born Wedel-Jarlsberg in 1821). In addition to Baldur’s son Moltke, the couple also had Adelaide’s five children from her previous marriage to care for (including Hjalmar Bølling, mentioned elsewhere in this blog). The couple soon had a new child, Frithjof, but he died only 15 months old. It’s possible the couple had yet another child, Minna, who died young, but I haven’t been able to confirm this.
On October 10, 1861, the couple had another son, also named Fridtjof. This son survived childhood and went on to become a well-known explorer, scientist and diplomat. A year later, the couple had another son, Alexander Christinus.
In 1877 Adelaide Nansen died, making Baldur a widower once again. Baldur never remarried. He died on April 2, 1885.
