Dinosaur Man
The man who first coined the term 'dinosauria', Sir Richard Owen, was born in July 1804. A pioneering biologist, Owen published a groundbreaking article in 1842 proposing a new name and suborder for dinosaurs – before that most scientists believed that different types of dinosaurs were unrelated. They're now known to be one group of large, extinct reptiles, which Owen called 'dinosauria' (from the Greek 'deinos' meaning terrible and 'sauros' meaning lizard).

Owen, who was also the driving force behind London's Natural History Museum, was a controversial figure, described by Charles Darwin as malignant and spiteful for his attacks on his theories of evolution. Owen's scientific reputation suffered as he got older and he was finally dismissed from the Royal Society's Zoological Council for plagiarism.
