He was born on March 1, 1949, to the late Roy and Angela Schmelzer of Sturgeon Bay, WI. John was born in Sturgeon Bay and spent his childhood there, helping his father at his restaurant, Roy’s Drive-In. He graduated from Sturgeon Bay High School in 1967 after earning the nickname “Smiley” for his friendly and lighthearted nature. He attended college at the University of Wisconsin, then transferred to the University of Florida after his parents moved there in search of warmer weather, graduating with a degree in Industrial Engineering in 1972. After starting his first job at the DuPont May Plant in Camden, SC, John met Karen Brannon and they were married on July 3, 1976. They moved to Durham in 1978 and raised their family there. He designed tobacco processing lines for the Liggett & Myers Company and built out a new facility for the U.S. Flue-Cured Tobacco Growers Cooperative, retiring from his role as plant engineer in 2011. John was a long-time parishioner at Immaculate Conception Catholic Church in Durham and led several outreach ministries, as well as cleanup and maintenance of the school grounds and play areas. He also loved classic rock and jazz music, traveling the world and tinkering in his garage workshop.
