John Weysser graduated from Lehigh in 1931 with a B.S. in mechanical engineering. While an undergraduate, he was a member of Theta Xi fraternity, the Mustard & Cheese Drama Society, and the soccer team. He continued his studies at Lehigh, receiving a Ph.D. in mining engineering 1937. Upon retirement, Weysser was a consulting engineer for mining, with a specialty in mine operation management and production. He originated the "long-hole" anthracite mining method for mining steeply while dipping anthracite seams. A contributor of articles to professional journals, he was also the author of Mine Transportation (1952) and the Pennsylvania Anthracite Mining Guidance Standards (1954).
With the belief that Lehigh University offers special opportunities for the education and training of young men and women, Weysser and his wife, Miriam, established an endowed scholarship that bears their name. Throughout their lives, the Weyssers maintained close ties to Lehigh as members of the Tower Society and University Associates of the Asa Packer Society. The Weyssers were participants in the university's planned giving program, supporters of Lehigh's Life Income Program, and scholarship program. They were especially interested in programs that were associated with earth science and engineering, as well as fuels and mineral products.
