Indonesian business magnate Michael Bambang Hartono, one of the owners of the Djarum Group and long regarded as the country’s richest man, has died at 85 in Singapore, leaving a legacy shaped not only by corporate success but by support for social initiatives that reached vulnerable communities.
Born Oei Hwie Siang on October 2, 1939, in Kudus, Central Java, Hartono built one of Indonesia’s largest business groups while maintaining a reputation for a modest personal life.
His legacy includes support for a Catholic-run orphanage in Lasem, Central Java, where members of the Soeurs de Notre Dame care for abandoned children. The Hartono family, which owns Djarum, donated a large property known as “Wisma Gadjah” to the congregation and provided financial assistance to improve the facility.
This support is part of the broader work of the Djarum Foundation, which supports programs in education, arts and culture, sports, and social development across Indonesia.

Hartono is survived by his four children.
Together with his younger brother, Robert Budi Hartono, he rebuilt a struggling family enterprise founded by their father, Oei Wie Gwan, into a major force in Indonesia’s economy.
What began as a small kretek cigarette factory in Kudus grew into Djarum, one of the country’s largest clove cigarette producers. The company expanded into international markets in the 1970s and launched Djarum Super in 1981, accelerating its growth.
The brothers later diversified their holdings, acquiring Bank Central Asia (BCA), now considered Indonesia’s largest private bank. Their business interests also expanded into electronics through Polytron, as well as digital platforms such as Blibli.com and Tiket.com.
According to Forbes, Hartono’s net worth reached between US$24.8 billion and US$25.1 billion, placing him at the top of Indonesia’s richest list.
Despite the scale of his business empire, Hartono was known for a leadership style that emphasized trust and delegation. He often compared business management to playing bridge, a game that requires strategy, discipline, and teamwork. Rather than overseeing daily operations closely, he entrusted responsibilities to capable managers and focused on guiding direction and evaluating results.
Hartono’s public image stood in contrast to his wealth. He was frequently seen dining at modest local eateries without heavy security, reflecting a personal lifestyle that remained understated. While he did not prominently present himself as a devout Catholic, the family has supported humanitarian initiatives through sustained contributions to social programs, including those assisting children and local communities.
Outside the corporate world, Hartono was an accomplished bridge player who represented Indonesia in international competitions. He won bronze medals at world championships and competed in the 2018 Asian Games in Jakarta. He later donated Rp1 billion in prize money to support the development of bridge communities in the country.
Hartono’s death marks the passing of a central figure in Indonesia’s economic life. His legacy is reflected not only in the companies he helped build, but also in institutions and communities that continue to benefit from those resources.
