Lloyd Chudley Alexander was an American author renowned for his contributions to children's and young adult literature. Born on January 30, 1924, Alexander authored more than 40 books, predominantly fantasy novels.

His most celebrated work is The Chronicles of Prydain, a series of five high fantasy novels. The series' conclusion, The High King, earned the prestigious 1969 Newbery Medal for excellence in American children's literature. Throughout his career, Alexander's works were translated into 20 different languages, and he was twice nominated for the international Hans Christian Andersen Award.

In addition to The Chronicles of Prydain, he received the 1971 National Book Award for The Marvelous Misadventures of Sebastian and the 1982 National Book Award for Westmark. He was recognized with three lifetime achievement awards.

Alexander's upbringing in Pennsylvania during the Great Depression instilled in him a love for reading and writing. Although he attended college for only a short period, he believed his educational pursuits were fulfilled elsewhere. He served in the United States Army, rising to the rank of staff sergeant in intelligence and counter-intelligence. His time in France led him to study French literature at the University of Paris, where he met his wife.

Back in the United States, Alexander initially struggled to support his family through writing until the publication of And Let the Credit Go in 1955. His fascination with Welsh mythology inspired his creation of The Chronicles of Prydain.

Alexander passed away on May 17, 2007. His legacy is preserved at Brigham Young University's Harold B. Lee Library, which maintains a permanent exhibit of his personal manuscripts and memorabilia.
