I Am Legend is a 1954 post-apocalyptic horror novel by American writer Richard Matheson that was influential in the modern development of zombie and vampire literature and in popularizing the concept of a worldwide apocalypse due to disease. The novel was a success and was adapted into the films "The Last Man on Earth" (1964), "The Omega Man" (1971), and "I Am Legend" (2007).
