Kevin Siembieda (born April 2, 1956) is an American artist, writer, designer, and publisher of role-playing games, as well as being the founder and president of Palladium Books. Palladium Books, founded in southeast Michigan, claims to be the first to implement a role-playing system intended to work for all genres and to introduce the perfect-bound trade paperback format to the RPG industry. Some of the role-playing games Siembieda helped produce include Teenage Mutant Ninja Turtles & Other Strangeness (1985), Robotech RPG (1986), After The Bomb (1986), and Rifts (1990). Siembieda is also an artist, best known for occasionally illustrating Palladium Books' products. In 1978, he started the now-defunct Megaton Publications in Detroit, publishing a digest style title called A+ Plus and several other titles. He also contributed art and cartography to several early Judges Guild products (for both their Traveller and Dungeons & Dragons lines).
