Leonard Gerald Cessac was born July 15, 1942 in Abbeville, LA, a son to the late Henry Joseph and Gussie (Stansbury) Cessac. Gerald earned a PHD in Physical Chemistry from the University of Maryland. On August 30, 1974 he married the love of his life, Susan J. Smittle, in Albuquerque, NM. Together, they’ve enjoyed nearly 47 years of marriage. Gerald was highly intelligent and curious about the world, working as a scientist and engineer through his entire education and career. He was a Distinguished Member of Technical Staff, specializing in national defense at the Sandia National Laboratory from 1972-2012. Gerald was an avid hunter and spent many days on his Missouri property enjoying what the land offered. Gerald had a passion for vintage automobiles, particularly Model “A” Fords. He was an active member of the Poco Quatros Model “A” Club out of Albuquerque. Gerald was also a retired member of the U.S. Coast Guard Auxiliary, selflessly volunteering his time to contribute to safety and security of United States citizens. He had a wonderful sense of humor and a big heart for his family. He will be deeply missed by family and friends. Survivors include his wife, Susan J. Cessac of Albuquerque, NM; three sons, Anthony Cessac of Albuquerque, NM, Kirk (Melodie) Cessac of Overland Park, KS and Nicholas (Ashley) Cessac of Albuquerque, NM; four grandchildren, Maryssa Cessac, Tori Cessac, Lucas (Emily) Lopez and Noah Lopez; one grandchild on the way; brother, Robert J.
