Hoesein Djajadiningrat
Husein Jayadiningrat, or Hoesein Djajadiningrat in older spelling (8 December 1886 – 12 November 1960), was an Indonesian scholar in Indonesian studies, Islamic law, and native Indonesian literature. He distinguished himself as one of the first native Indonesian to earn a doctoral degree. Early life 
Hoesein, nicknamed 'Ace', was born on 8 December 1886 in Kramatwatu, a subdistrict of Serang, a Regency within the Residency of Banten, Dutch East Indies. His father was Raden Bagoes Djajawinata (1854-1899), the previous Bupati or Regent of Serang. His mother is Ratoe Salehah (1862–1903) of Cipete, Serang. Hoesein is born fifth in order of nine children; the eldest son Achmad (nicknamed Uyang), Mochammad (Apun), Hasan (Emong), Hoesein (Ace), Chadijah (Enjah), Loekman (Ujang), Soelasmi (Yayung), Hilman (Imang), and Rifqi (Kikok). Hoesein's family was an aristocratic one, considered part of the priyayi class in Javanese society. His paternal uncle Soetadiningrat and paternal grandfather Natadiningrat was Regent of Pandeglang, another region also in Banten. His elder brother Achmad would succeed their father as regent, initially as Regent of Serang, later transferred to serve as Regent of Batavia. His brother Achmad first used the name 'Djajadiningrat' as his surname prior from taking final examination for the Hogere Burgerschool in Batavia. Soon after, his siblings, including Hoesein, adopted the surname. His family, the Djajadiningrat family would prove to be an influential family during the Indonesian National Revolution (1945–1949), where various members of the family would play parts on both side of the conflict. Education 
As member of the aristocracy, Hoesein was expected to be educated in western style education after receiving early Islamic religious education, pesantren-style as was common in Banten. Soetadiningrat was particularly enthusiastic in providing education to his family members especially for his nephews and nieces. In late 1880s, the family was introduced to Snouck Hurgronje, an accomplished scholar and advisor for the colonial government of the Dutch East Indies. In 1890 he offered to foster Achmad in providing his education as a future regent. Although smart, he was not as enthusiastic in education as Hoesein, who Hurgronje also offered to foster later. In 1904 Hoesein graduated from HBS in Serang and promptly sent to the Netherlands to pursue higher education. He went to learn Dutch at Leidsche Gymnasium for a year, then enrolled as a student at Leiden University, attending lectures on ethnography, cultures, and native Indonesian languages. Later in 1907 Hurgronje returned to the Netherlands and gave lecture on Arab cultures; he became Hoesein's education supervisor as well. He graduated with cum laude, earned his degree on Oriental Studies in 1910, and immediately pursued doctoral degree. Three years later, he would eventually earn his doctoral degree, after defend his dissertation titled "A Critical Study on the History of Banten" (), supervised by Hurgronje. His dissertation examination committee, which included Professor Kern, noted that it was well made and critically needed for historical studies of Banten. Career 
After graduating, he first stayed in Aceh in order to study the language, as well as to wrote an Acehnese–Dutch dictionary. The research was conducted from April 1914 to May 1915, and finally published as a two-volume dictionary entitled Atjehsche Nederlandsch Woordenboek, which would be publish years later in 1934. In 1924 he was appointed as a professor at Batavia Law School (), giving lectures on Islamic law as well as native Indonesian literatures and languages. Since 1935 he worked as manuscript conservator at the Royal Batavian Society of Arts and Sciences (). Initially served as board member, he would later lead it until 1941. Along with it he also served as member of the Council of the Indies (, separate body from the Volksraad). During Japanese occupation of the East Indies (1941–1945), the Japanese authorities appointed him to head the Office of Religious Affairs, replacing the previous officials who left Java alongside the rest of the colonial government to Australia. Alongside them was his younger brother Loekman, who would serve in the Dutch East Indies Government-in-Exile in Australia as commissioner and later head of the education department. He later died in Sydney in 1944. During this time as well, his older brother Achmad died after bout of illness in 1943. Around this time, he was involved in Indonesian national movement, later became a member for the Investigating Committee for Preparatory Work for Independence () or BPUPK. During the drafting of the would-be Indonesian 1945 Constitution, he served in the Vocabulary Committee (), alongside Agus Salim and Soepomo. For a while after the end of Japanese occupation he joined the Indonesian cabinet, serving as the State Secretary for Education, Culture, and Science in 1948. Later during the Dutch military occupation of west Java during Operation Product, he was asked to serve as chair of the Association of United States of Indonesia Movement, promoting the formation of the United States of Indonesia. His younger brother Hilman, who succeeded Achmad as Regent of Serang in 1935 (later served as well as Japanese-appointed Resident of Banten from 1941 to 1945) became active in West Javan politics, as he led the pro-Dutch, federalist faction in the State of Pasundan. In 1948 Hilman was appointed governor of Djakarta Federal District, serving until 1950. In 1950 he joined the newly created University of Indonesia as a lecturer in its Faculty of Letters. Two years later, he became a professor of Islamic Studies and Arabic Language. Later in 1957 he became the general director of – and member of the Vocabulary Commission () at – the Language and Culture Office () under the Faculty of Letters, serving until his death in 1960.
