Dr. Robert C. Krug
Dr. Robert Krug was appointed the President of George Mason University in April of 1977. Before coming to George Mason Dr. Krug worked mainly in research for many different places. He worked for Ohio State University and the Atlantic Refining Company doing research. While he was at Ohio State he got his Ph.D. in chemistry. 
Dr. Krug's first teaching position was with Washington and Lee University, where a colleague of his asked him to step in and teach for a year. That was where Dr. Krug fell in love with teaching. After that position expired Dr. Krug sought out another teaching position with Virginia Polytechnic Institute, which was later renamed Virginia Tech.  While at VPI, Dr. Krug was one of the first recipients of the W. E. Wine Award for distinguished teaching at VPI in the School of Business Administration and Applied Science. 
Dr. Krug's history with George Mason College and George Mason University began in 1965 when he was asked to meet with Joseph Vaughan, Chancellor of Community Colleges at the University of Virginia. Dr. Krug also met with President Edgar F. Shannon of the University.
Shortly after the interview, he had several offers for different positions within George Mason College, including Chairman of the Chemistry Department. A short while after he was hired he was asked by Chancellor Vaughan to draft a proposal that would declare George Mason College a four-year college under the University of Virginia. 
When George Mason College declared independence and became George Mason University, Dr. Krug became the Provost and then Vice-President of Academic Affairs. When Dr. Dykstra left George Mason University, Dr. Krug accepted the position as Acting President under the stipulation that this would not be a permanent position.  It seemed clear that Dr. Krug didn't want to be president because he loved teaching and interacting with the student on campus.
