Lloyd J. Guggenberger

Lloyd Joseph Guggenberger, age 75, of Summer- field, FL, passed away on Tuesday, March 17, 2015 leaving his loving wife Libby, his family and his friends to cherish his memory. Born on September 11, 1939 in Cold Spring, MN to the late Norbert and Julia Karst Guggenberger, Lloyd was loved by his siblings, Rita Meier (Al), Carol Manuel (Tom), June Rossman (Jerry) and Dale Guggenberger (Deb), his nieces and nephews and their children. Lloyd and his first wife, Mary Iten, raised three children; Sandra (John Yannacone), Paul (MaryAnn) and Steven (Jodi). He was deeply proud of his six grandchildren, Nicholas and Steven Yannacone, Katherine Guggenberger, and Madeline, Maxwell and Emma Guggenberger. In 2004 Lloyd married Libby Gray McGehee. Together they enjoyed 10-1/2 happy years of marriage. He is survived by Libby's children Barrett McGehee and Amy Yochis (Joe) and Amy and Joe's children Jamy, Dylan and Michael Yochis. Lloyd graduated from St. Boniface High School where he participated in basketball and football and was involved in many other activities. In reflection, he noted that his broad involvement may owe more to his inability to say no to the nuns rather than any particular keen interest in the activities themselves. He attended St. John's University in Collegeville, MN graduating in 1961 with a major in Chemistry and a minor in Mathematics. Lloyd went on to Graduate School at Iowa State University, Ames, Iowa where he earned his PhD in Physical Chemistry in 1965. During graduate school, Lloyd worked for the Atomic Energy Commission at the Ames Laboratory. His thesis, "The Structures of the Ethyl Grignard Reagent in Diethyl Ether and a Troponoid Photo-Oxidation Product," as incomprehensible as it may be, is available online for your reading. After earning his PhD, Lloyd moved his family to Wilmington, Delaware where he joined the DuPont Company as a research chemist in the Central Research and Development Department at the Experimental Station. For ten years, Lloyd's research focused on new materials, many of which are now household names. His work is published in scientific journals and has been widely cited by his peers. His career evolved into management and other leadership roles, including an assignment in Louisville, KY in the early 1980s. Coworkers and colleagues are always quick to share a story or anecdote about Lloyd. He was a strong presence in the office and a key mentor to many who worked with him. Lloyd retired in 1996. As his children grew, they heard little about his work, though they often got help with math homework and played at his home office desk surrounded by ball and stick models of chemical compounds. He was a coach and scout master, teacher and chauffer, playmate and role model. He was good at everything he tried. In 2004 Lloyd and Libby settled in Summerfield, FL. In retirement, Lloyd learned to relax, though he would still research and prepare a tabbed, three-ring binder response if you were fortunate enough to know him and ask him a question. Lloyd made good friends, pursued his interest in genealogy and enjoyed traveling. He left too many places unvisited. Lloyd was a brilliant man; gentle, inspiring, quirky, caring, generous and supportive. He was a rock who was always there for family, friends, coworkers, and acquaintances. He has touched many of us and will be missed terribly.
