About the Author

James H. Schmitz (1911-1981) was born in Hamburg, Germany, to American parents. Aside from several trips to the USA, he lived in Germany until 1938, when the outbreak of WWII prompted his family to move to America. He sold his first story, "Greenface," to the now-legendary magazine Unknown Worlds shortly before Pearl Harbor. By the time it was published, he was flying with the Army Air Corps in the South Pacific.

In 1949, he began publishing his Agents of Vega series in Astounding (later Analog), and was one of that magazine's most popular contributors over the next three decades, introducing Telzey Amberdon and Trigger Argee, the heroines of his Federation of the Hub series. He was a master of space opera adventure, notably represented in his classic novel, The Witches of Karres, but also demonstrated in many other novels and shorter works.
