charged with improving the state’s position as a national leader in scientific and technical research and development.
Mark’s contributions to the industry were acknowledged throughout his career. In 1962, LIFE magazine selected him, at the age of 39, as one of the 100 most important young people in the United States. LIFE recognized his role in leading the development of transistor mass production and in helping make TI the world’s leading producer of semiconductors.
Mark was elected a member of the National Academy of Engineering in 1970 “for technological contributions and leadership in the growth of the semiconductor electronics industry.” Alumni organizations at both SMU and the University of Illinois recognized Mark for his distinction. He was awarded an honorary doctorate of engineering from SMU in 1966 and another from Rensselaer Polytechnic Institute in 1979. He also received the Horatio Alger Award in 1984.
Mark perhaps summarized his legacy best when he recalled: “Not many people in their lives have the opportunity—and the privilege—of helping to build not only a company, but also an industry that has had as profound an impact on society as the semiconductor industry. I am grateful for that privilege.”
He is survived by his widow, Mary Alice Shepherd, and three children.
