James H. Schmitz
James Henry Schmitz (1911–1981) was an American writer born in Hamburg, Germany of American parents.
Schmitz is best known as a writer of so-called "space opera", and for strong female characters (such as Telzey Amberdon and Trigger Argee) that didn't conform to the damsel in distress stereotype typical of science fiction during the time he was writing. His first published story was Greenface, published in August 1943 in Unknown.
Most of his works are part of the "Hub" series, though his best known novel is The Witches of Karres, concerning juvenile "witches" with genuine psi-powers and their escape from slavery. Karres was nominated for a Hugo Award. During recent years, his novels and short stories have been republished by Baen Books, edited and with notes by Eric Flint.
