Leo Frankowski

Leo Frankowski (1943-2008) was an American science fiction author best known for his Cross-Time Engineer series and the Adventures of Conrad Stargard novels. His works primarily dealt with themes of technological advancement, alternate history, and the impact of modern knowledge on medieval societies. The Cross-Time Engineer series follows Conrad Schwartz, a Polish engineer accidentally transported to 13th century Poland, who uses his modern technical knowledge to industrialize medieval society and prepare for the coming Mongol invasion. These books showcase detailed descriptions of engineering processes and technological development within a historical context. Frankowski was also an engineer by profession, having worked in the automotive industry, and this technical background heavily influenced his writing style and subject matter. His other works include the New Kashubia series and Two Space War, though these achieved less commercial success than his Conrad Stargard books. Prior to his writing career, Frankowski served in the U.S. Army and later operated his own engineering company in Sterling Heights, Michigan. He passed away in 2008 in Lake Elsinore, California.
