Happy Birthday: George Raymond Richard Martin (born George Raymond Martin; September 20, 1948) also known by the initials G.R.R.M. is an American author, television writer, and television producer. He is best known as the author of the series of epic fantasy novels A Song of Ice and Fire, which were adapted into the Primetime Emmy Award–winning television series Game of Thrones (2011–2019) and its prequel series House of the Dragon (2022–present). He also helped create the Wild Cards anthology series and contributed worldbuilding for the video game Elden Ring (2022).

In 2005, Lev Grossman of Time called Martin "the American Tolkien", and in 2011, he was included on the annual Time 100 list of the most influential people in the world. He is a longtime resident of Santa Fe, New Mexico, where he helped fund Meow Wolf and owns the Jean Cocteau Cinema. The city commemorates March 29 as George R. R. Martin Day.

Martin began selling science fiction short stories professionally in 1970, at age 21. His first sale was "The Hero", sold to Galaxy magazine and published in its February 1971 issue; other sales soon followed. His first story to be nominated for the Hugo Award and Nebula Awards was "With Morning Comes Mistfall", published in 1973 in Analog magazine. In 1975 his story "...for a single yesterday" about a post-apocalyptic timetripper was selected for inclusion in Epoch, a science fiction anthology edited by Roger Elwood and Robert Silverberg. His first novel, Dying of the Light, was completed in 1976 right before he moved to Dubuque and published in 1977. That same year the enormous success of Star Wars had a huge impact on the publishing industry and science fiction, and he sold the novel for the same amount he would make in three years of teaching.

In 1991, Martin briefly returned to writing novels. He had grown frustrated that his TV pilots and screenplays were not getting made and that TV-related production limitations like budgets and episode lengths were forcing him to cut characters and trim battle scenes. This pushed Martin back towards writing books, where he did not have to worry about compromising his imagination. Admiring the works of J. R. R. Tolkien in his childhood, he wanted to write an epic fantasy, though he did not have any specific ideas.

His epic fantasy series, A Song of Ice and Fire, was inspired by the Wars of the Roses, The Accursed Kings and Ivanhoe. Though Martin originally conceptualized it as being three volumes, it is currently slated to comprise seven. The first, A Game of Thrones, was published in 1996, followed by A Clash of Kings in 1998 and A Storm of Swords in 2000. In November 2005, A Feast for Crows, the fourth novel in this series, became The New York Times No. 1 Bestseller. The fifth book, A Dance with Dragons, was published July 12, 2011, and became an international bestseller, including achieving a No. 1 spot on the New York Times Bestseller List and many others; it remained on the New York Times list for 88 weeks.
