Allen Appel, American author, illustrator, and photographer
Allen Appel (born January 6, 1945) is an American novelist best known for his series about time traveler Alex Balfour. In the series, fictional characters are interwoven with actual historical people and events.

Born in Bethlehem, Pennsylvania, Appel grew up in Parkersburg, West Virginia. He graduated from West Virginia University in 1967 and moved to Washington, D.C., where he found work as an illustrator and photographer. He made his mark with a series of collage illustrations for the Sunday magazine section of The Washington Post, and this work led to his first book, Proust's Last Beer: A History of Curious Demises (1980), a collaboration with writer Bob Arnebeck. Appel's imaginative black-and-white collages illustrated Arnebeck's profiles of people and animals.
