On 2 April 1970, Basilio dies and his brothers and sisters become heirs to the Leonidas empire “Confiserie Leonidas SPRL” (Leonidas Confectionery SPRL). Jean Kesdekoglu-Kestekides leads the company from 1970 to 1985 and the brand eventually goes international selling in Belgium, Luxembourg, Germany, Holland, at Harrods in London and even in Athens. On 29 March 1979, Confiserie Leonidas becomes Leonidas SA, a limited company. The 70s and 80s were the company’s golden years. Attracted by the chocolate’s delicacy, people were desperate to get their hands on them. To increase production, Confiserie Leonidas SA buys the old Crown-Baele factory at 41-43 Graindor Boulevard in Anderlecht which remains the company headquarters. Maria Kesdekoglu-Kestekides joins his father Jean, helping him carry out daily operations.
