Like many other Americans, Chandler "Chan" Weaver followed the example of the pioneers and went west "to grow up with the country," settling in Denver. While at Lehigh, the Philadelphia native studied mining engineering, and was a member of Chi Phi fraternity. His westward trek led to jobs with a number of organizations, including Link Belt Company, Shale Oil Machinery and Supply Company, Public Service Corporation of Colorado and Surface Combustion Corporation.
As president of the Realty Company, Denver, Weaver managed his family interests in a number of enterprises, including banking, silver mining and sugar beet farming. He also worked as a consulting engineer. One of his projects, a plant for the commercial production of oil from the shale deposits of western Colorado, attracted a great deal of interest in the early 1970s as people began to search for new sources of energy.
His bequest established the Chandler Weaver Chair of Engineering and Science and was used to endow a scholarship, with a preference given to students from Colorado.
