Prince of Sweden and Norway, as the only son and younger child in the marriage of Crown Prince Carl (later King Carl XV and IV) of the United Kingdoms of Sweden and Norway (1826–1872) and Princess Louise of the Netherlands (1828– 1871). He had one elder sibling, Louise of Sweden, who would become Queen of Denmark.
In February 1854 the young prince suffered from the measles, and was prescribed a cold bath. This led to pneumonia, and the prince died on 13 March when he was little over a year old.
