Harry Brodribb Irving (5 August 1870 - 17 October 1919) was a British stage actor and actor-manager, known as the eldest son of Sir Henry Irving and Florence Irving. He initially pursued law, studying at Marlborough College and New College, Oxford, but decided to become an actor and adopted the stage name H.B. Irving. He made his debut at the Garrick Theatre in London and later toured successfully in the United States. Irving married actress Dorothea Baird and had two children, Laurence and Elizabeth. He performed in his father's company before branching out and joining George Alexander at the St James's Theatre. Following his father's death, Irving established his own company and toured extensively, often reprising his father's roles. He also made contributions to film and directed the 1910 British adaptation of the Jekyll and Hyde story. During World War I, Irving focused on law and wrote the renowned book "A Book of Remarkable Criminals" in 1918. He was a founding member of Arthur Conan Doyle's Our Society and passed away in 1919 after a prolonged illness.
