Sabin Manuilă (or Mănuilă; February 19, 1894 – November 20, 1964) was an Austro-Hungarian-born Romanian statistician, demographer and physician. A nationalist activist during World War I, he became noted for his pioneering research into the biostatistics of Transylvania and Banat regions, as well as a promoter of eugenics and social interventionism. As a bio- and geopolitician, Manuilă advocated the consolidation of Greater Romania through population exchanges, colonization, state-sponsored assimilation, or discriminatory policies.Manuilă entered national politics in the early 1930s, representing the National Peasants' Party as a junior cabinet member. A disciple of the sociologist Dimitrie Gusti, who obtained him a membership in the Romanian Academy, he directed Romania's first Statistical Institute. During World War II, he rose to prominence as an expert adviser of Romanian dictator Ion Antonescu, applauding the antisemitic legislation and making antiziganism an official policy of the Romanian state. He was among the first intellectuals to propose the deportation of Romanian Jews and Romanies into occupied Transnistria. Additionally, Manuilă involved himself in the diplomatic standoffs between Romania and the Kingdom of Hungary, fighting against the loss of Northern Transylvania, then campaigning for her recovery.By 1944, Manuilă was an Antonescu opponent, and involved himself in the August coup that toppled him. He remained active on the political scene even after the start of Soviet occupation, serving as Undersecretary of State on two successive coalition governments. He fell out with the Romanian Communist Party, and escaped the country before the imposition of a communist regime, rallying with the Romanian National Committee. He lived his final years in the United States, employed by Stanford University and the Census Bureau.
