John Byron (British Army officer)
Captain John Byron was a British Army officer and letter writer, best known as the father of the poet Lord Byron. In 1824, an obituary of his son gave him the nickname "Mad Jack Byron", and though there is no evidence for this in his own lifetime, it has since stuck – certainly he was called "Jack" by his family members and referred to himself as such.
Lord Byron's father, Captain John "Mad Jack" Byron
George Gordon Byron, 6th Baron Byron, was a British poet and peer. He is one of the major figures of the Romantic movement, and is regarded as being among the greatest of English poets. Among his best-known works are the lengthy narratives Don Juan and Childe Harold's Pilgrimage; much of his shorter lyrics in Hebrew Melodies also became popular.
