Prince Leopold, Duke of Albany was the youngest son of Queen Victoria of the United Kingdom, born on April 7, 1853. He was diagnosed with hemophilia at a young age, which severely affected his life. Despite this, he received a good education, studying at Oxford University and pursuing a career as a soldier. He was appointed colonel of the 72nd Highlanders and later became a general. In 1882, he married Princess Helena of Waldeck and Pyrmont, with whom he had two children. Unfortunately, Prince Leopold's health deteriorated, and he died at the age of 30 from a massive hemorrhage caused by a fall. Throughout his life, Prince Leopold was known for his intelligence, kindness, and devotion to his family, despite his hemophilia always being a major obstacle in his life. His death was a great loss to his family and the British royal family.
