David Mark Weber is an American science fiction and fantasy author. He was born on October 24, 1952, in Cleveland, Ohio. Weber is renowned for his military science fiction series, especially the Honor Harrington series. He often explores military, particularly naval themes, and frequently features female protagonists in traditionally male roles.

His first novel, co-written with Steve White, was sold to Baen Books in 1989, which remains his primary publisher. One of the hallmarks of his work is a set of fixed laws that hold constant even in the magical realms of his fantasy writings. Weber's work also delves into the issues of a gender-neutral space Navy.

Over the years, he has expanded the Honorverse with novels not directly involving Honor Harrington, collaborating with authors like Linda Evans, John Ringo, and Eric Flint. As of spring 2013, the Honorverse includes 16 novels and six shared-universe anthologies.
