Roberto A.Nunez passed away on September 3, 2025 in Stuart, Florida. Roberto was born in Havana on February 6, 1941. He was a freshman at the University of Havana studying mechanical engineering when the revolution occurred in 1959. The government subsequently took possession of his father's business and it became unsafe for him to stay. Roberto, 18 years old at the time, was sent alone on a transatlantic freighter to Barcelona, Spain. Homeless and penniless, but intelligent and desperate, he found work tutoring college students in mathematics at the University of Barcelona. A music lover with a booming, melodic operatic voice, Roberto would find his way into the Gran Teatre del Liceu where he would spend his evenings listening intently from unoccupied opera boxes. He was offered a free education at the University of Barcelona by professors who recognized his intellect. He was also offered tutelage under one of Europe's finest tenors who recognized his talent. On hearing rumblings that the United States was planning an invasion to liberate his homeland, Roberto turned away from his opportunities, applied for emigration and flew into New York City. Shortly after his arrival he enlisted in the US Army. Despite speaking no English, he tested highly and was selected to serve in the elite 101st "Screaming Eagles" Airborne Division where he rose to rank of sergeant. After his service, Roberto returned to New York City and pursued an education in the nascent field of computer programming. He met his wife Zoila Eva, was married and moved to Newark, New Jersey. Starting in the late 1960s, he developed and refined computer-based inventory tracking systems that would go on to become industry standards. After retiring from his career as a systems analyst in 2006, Roberto retired to Florida to be closer to family. He was pre-deceased by his wife and soulmate Zoila, whom everyone knew as Nancy, in 2015. He is survived by his son, Robert A. Nunez, M.D., and his granddaughters Jade Nunez (a student at Brown University School of Medicine) and Jasmine Nunez (a student at the University of Pennsylvania Wharton School of Business). A good man with a kind heart and a keen mind, he will be missed by everyone who was fortunate enough to have met him.
