After graduating from Maryland in 1951, George Laurer joined IBM as a junior engineer and worked up the ranks to senior engineer. In 1969, he returned to the technical side of engineering and was later assigned the monumental task of designing a code and symbol for product identification for the Uniform Grocery Product Code Council. His solution — the Universal Product Code — radically changed the retail world. Since then, he has enhanced the code by adding a 13th digit. Laurer retired from IBM in 1987. He holds some 25 patents and is a member of the university’s A. James Clark School of Engineering Hall of Fame.
