Day Anthony DeRosa passed away on Sunday, December 28, at Charter Senior Living in Madison, Wisconsin, two days after his 88th birthday.

Born to Frank and Jennie (Marino) DeRosa on December 26, 1937, Day grew up in Bridgeport, Connecticut, and attended Warren Harding High School.

Day was gifted with an innate mechanical ability, purportedly rebuilding his father’s 1950 Cadillac engine at age 15 with no prior schooling. He consequently worked many years for Avco Lycoming in Stratford, Connecticut, working his way up from the factory floor to management. He then spent 25 years as a quality assurance inspector for the Federal Aviation Administration (FAA), traveling the world to industrial plants in Germany, Italy, England, Sweden, and Japan on numerous occasions.

He retired in August 2005 and fulfilled his dream of moving to Florida, building a home in Venice that was his pride and joy and the pinnacle of his creative achievements.

Day was a life-long car enthusiast and owned, maintained, and built many classic and collectible cars over the years.

He is survived by his sister, Joan Bogen, his sons Day DeRosa, Jr, of Milford, Connecticut, and Doug DeRosa, and grandsons Enzo and Gino DeRosa, of Monona, Wisconsin.

He was preceded in death by his loving wife of 68 years, Agnes (Kranyik) DeRosa, and siblings Peggy and Vincent DeRosa, Terry Pavone, and Barbara Paul.

Day will be entombed with Agnes at Mountain Grove Cemetery in Bridgeport, Connecticut.

A celebration of Day's life will be held at GOOD OLE DAYS PIZZA & COCKTAIL DEN, 19 Main St., Newtown, Connecticut, from 12 noon to 3 p.m. on Saturday, March 28, 2026.
