Raymond C. Simonis 3d, 48, of Ambler, a machinist and volunteer firefighter, died Wednesday at Abington Memorial Hospital of heart failure.

Born in Philadelphia, he was a graduate of Abington High School, where he played football. He was a volunteer firefighter with the Wissahickon Fire Company and Haz-Mat Team 919. He also was the fire chief at SPS Technologies in Jenkintown, where he worked for 28 years as a machinist.

Deputy Fire Chief Deputy Anthony Minio said Mr. Simonis had worked at a fire in Upper Dublin Township less than 24 hours before he died. "It's pretty grim around here right now," Minio said. "He was just a happy-go-lucky guy - he never had a bad day."

Mr. Simonis enjoyed fishing and football, especially watching the Eagles.

He is survived by his wife of nearly 25 years, Christina M. LaRuffa Simonis; daughters Marika, Alyssa and Gabriella; and his parents, Raymond C. and Estelle Rammos Simonis Jr.
