Count Stanisław Julian Ostroróg (1836– 31 May 1890) was an exiled Polish nobleman and Crimean War veteran. He later became known as an early professional portrait photographer who created photogravures, under the professional name of Walery, of many notable contemporaries, including Queen Alexandra of Denmark, Queen Victoria, Victor Hugo, and Sarah Bernhardt. After his death, his brand, "Walery", was continued by his eldest son, Stanisław Julian Ignacy Ostroróg in London and Paris, sometimes also as "Lucien Walery" and a range of other related pseudonyms.
