Continuing her Wikipedia article - "The couple had no children, probably because of Charles' homosexuality. Olga's husband became the object of scandal several times for his closeness with various men. The most notorious of these was the American Charles Woodcock, a former chamberlain whom Charles elevated to Baron Savage in 1888. The resulting outcry forced Charles to renounce his favorite. In 1863, Olga and Charles adopted Olga's niece, Grand Duchess Vera of Russia, the daughter of Olga's brother Grand Duke Constantine.* On June 25, 1864, after the death of his father, Charles acceded the throne and became the third king of Wurttemberg, making Olga the fourth queen of Wurttemberg. The new king was enthroned on July 12, 1864.* With no children of her own, Olga dedicated her life to social causes. She was especially interested in the education of girls, and also supported wounded veterans and the handicapped. A children's hospital of Stuttgart, the Olgahospital, was named for her in 1849; and an order of Protestant nursing nuns of Stuttgart, the Olgaschwesternschaft, was named for her in 1872. These charitable enterprises made her very popular among her subjects, much more so than her husband.* Olga was very interested in natural science and collected minerals systematically. Her collection was bequested to the Staatliche Museum fur Naturkunde in Stuttgart. The museum still proudly displays some of these mineral specimens of royal origin. Her name is attached to a geological formation in the Northern Territory, Australia. In 1871, to mark their 25th wedding anniversary, Charles and Olga elevated the German-born Australian explorer Ferdinand Mueller to "Baron von Mueller." He repaid the compliment as follows. A series of massive rock formations was discovered by the British-born Australian explorer Ernest Giles in central Australia in 1872. Mueller was Giles' benefactor. Giles had wanted to name the tallest peak Mt. Mueller, but Mueller prevailed on Giles to name it Mt. Olga, in honour of the queen. The entire geological formation then became known as 'The Olgas,' before the indigenous name "Kata Tjuta" was officially proclaimed in the 1980s.*
