Charles Pappaconstantinou, 73, died on June 22, 2012 at Hospice House in Callaway, MD, surrounded by his loving family, after a courageous battle with cancer. Born April 27, 1939, in Lowell, MA, he was the son of the late Angelo Pappaconstantinou and Sophie Panas.

Charles graduated from Lowell Technical College in 1961. He joined the United States Army in May 1962 and was honorably discharged in May 1964.

On July 9, 1965, he married his late wife, Mary Daly Pappaconstantinou in La Plata, MD where they enjoyed 46 wonderful years together and raised their three sons.

He worked for the Department of Defense in Indian Head as a mechanical engineer and was promoted to the Department Head of the Engineering Department and the Test Department. He retired after more than 30 years of Civil Service and received many performance awards along the way. He was an avid golfer and enjoyed playing poker with his buddies. However, his greatest passion was his grandchildren. He loved to attend all of their sporting/school events and spent as much time as possible with them.
