| GEORGE J. LAURER
B.S. 1951 ENGINEERING INDUCTED JUNE 10, 2000 |
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.
