J. B. Sumarlin  Johannes Baptista Sumarlin (7 December 1932 – 6 February 2020) was an Indonesian economist who served as Minister of Finance. Sometimes linked with the so-called Berkeley Mafia group of economic advisers which included senior Indonesian economists such as Widjojo Nitisastro, Emil Salim and Ali Wardhana, Sumarlin held various important economics posts in the Indonesian government for many years until the late 1990s. He graduated from the Faculty of Economics, University of Indonesia (FEUI) in 1958. Positions held in government included, among others, Chairman of Supreme Audit Agency, Minister of Finance, Chairman of the National Planning Agency (Bappenas), and Minister for Administrative and Bureaucratic Reform. Sumarlin graduated with an M.A. in economics from the University of California, Berkeley in 1960, and a doctorate from the University of Pittsburgh in 1968. His master's thesis was about "Some Aspects of American and Indonesian Fiscal and Monetary Policies: A Comparative Study" and his doctoral's thesis was entitled "Some Aspects of Stabilization Policies and Their Institutional Problems: The Indonesian Case 1950-1960". After graduating with an undergraduate degree (S1 in the Indonesian system) at the University of Indonesia in 1958, Sumarlin served as a teaching assistant for some years. In 1965 he was appointed as a lecturer in the FEUI, then as a professor in 1979. Previously, he had worked in an industrial company in Jakarta. During earlier political struggles, Sumarlin had worked as a member of the Indonesian Red Cross, and as a recruit in the Indonesian army ("Tentara Nasional Indonsia", or TNI) in East Java. For his service, in 1973 he received the "Mahaputra Utama" star, one of the highest honours awarded in Indonesia. Two years later he was awarded the Grand Cross in the Order of Leopold II of the Belgian government. In his private life, Sumarlin was a sports enthusiast and enjoyed tennis and jogging. He was married to Th. Yostiana Soedarmi. Together they had four children. Sumarlin had a slight build and this was associated with an incident that became well known among his colleagues in Jakarta. Around 1969, during the early stage of the work of the New Order government of president Soeharto, in his position as Deputy Minister of the Indonesian National Planning Agency, Bappenas, Sumarlin was often required to accompany the Chair of Bappenas, Professor Widjojo Nitisastro, to Cabinet meetings.
