Pumpuang Duangjan

Ramphueng Chithan (Thai: รำพึง จิตร์หาญ; 4 August 1961 – 13 June 1992), known professionally as Pumpuang Duangjan (Thai: พุ่มพวง ดวงจันทร์; RTGS: Phumphuang Duangchan), was a Thai singer and actress. Honored as the "Queen of Luk Thung", she is one of the most celebrated luk thung vocalists in Thailand.

The child of poor farmers, Pumpuang had only two years of primary education before her family's plight forced her to take to the fields as a sugar cane cutter. Although illiterate, she was adept at memorising lyrics and participated in many local singing competitions. At age 15, she came to the notice of a visiting band, Waiphot Phetsuphan, and from the late 1970s onwards, her fame skyrocketed. Her lyrics often spoke about Thailand's rural poor. She adapted pleng luk thung (Thai country music) into a dance-ready form known as electronic luk thung. Although loved by millions of fans, Pumpuang's music career was marred by her lovers, managers, and promoters, who deprived her of her earnings. Due to this, she could not afford treatment for lupus, which eventually caused her death at the age of 30.

In 2018, she was featured as a Google Doodle in Thailand on what would have been her 57th birthday

In Thailand, lupus is colloquially referred to as 'Phumpuang's disease,' (Thai: โรคพุ่มพวง; RTGS: Rokh Phumphuang) following the death of Phumpuang from the illness, which brought widespread public attention to the condition.
