Prior to joining Esterline Power Systems as president, Mark Thek was a physicist and engineering director at Hughes Aircraft Company in Los Angeles, California. Mark Thek is a nephew to Paul Thek, a famous and accomplished artist. Paul is widely exhibited throughout the United States and Europe. The artist is famous for his technological reliquaries or meat pieces, which involved creating wax sculptures in the likeness of raw meat and mutilated human limbs encased in Plexiglas vitrines. One such sculpture is the Warrior's Leg made from wax, leather, metal, and paint. The sculpture, which possibly represents the leg of a warrior unceremoniously cut off, is a cast from part of a leg, painted in realistic detail and adorned with a leather sandal and greave. Some of the reasons used to explain the idea behind this type of art include Paul’s visit to Catacombs in Palermo, Sicily, and from religious art he had seen in Italy. Another reason is the anti-war movement that was gaining ground due to the US government becoming actively involved in the war in Vietnam.
