John passed away last month age 90 following a short battle with lymphoma, his family have said - just 10 days before his 91st birthday.
His funeral was held on Wednesday (June 6) at the St Sarkis Armenian Church in Kensington, followed by a reception at the Centre for Armenian Information and Advice (CAIA).
Born in Ethiopia, John moved to Cyprus with his parents and brother when the family fled Ottoman persecution. He met partner Gwynneth and relocated to the UK after the pair got married.
