Lê Văn Thiêm was born in 1918 at Trung Lễ Commune, Đức Thọ District, Hà Tĩnh Province, to an intellectual family. He was the youngest of 13 brothers and sisters. After the death of his parents in 1930, he moved to live with his older brother in Quy Nhơn and attended the Collège de Quy Nhơn, where Thiêm stood out in science and mathematics. Within four years, he had completed the 9-year education and went to University of Indochina for his higher education. Because of the humble scale of the university at that moment, no Math course was offered. Therefore, he enrolled in the PCB class. In 1939, after passing the final term examination excellently, Thiêm was offered a scholarship to study at École Normale Supérieure. His education was interrupted by the outbreak of the Second World War, and only continues in 1941. He graduated with bachelor's degree of Mathematics within a year, rather than the conventional 3-year time. Under the direction of Professor Georges Valiron, he defended his Ph.D. dissertation successfully in Germany at 1945 and then moved to the University of Zurich where he met and worked with Rolf Herman Nevanlinna for some years.His contributions in Paris and Zurich placed him among the best researchers in mathematics in the 1940s. In 1949, following the call of Hồ Chí Minh, Thiêm returned to Vietnam to support the war of decolonizing Vietnam. Moving through many positions in North Vietnam's science institutions and government, in the mid-1950s he was appointed headmaster of the National University of Advanced Education and School of Basic Science. In the 1960s, he was one of the scientists who suggested opening two national high schools to foster Vietnamese mathematics talents. In 1970 he became the first director of the Vietnam Institute of Mathematics. Later, he founded and was first editor-in-chief of two of Vietnam's Mathematical Journals: Acta Mathematica Vietnamica and Vietnam Journal of Mathematics. He was the host of Neal Koblitz in his lectures in Vietnam. Lê Văn Thiêm died in 1991 in Hồ Chí Minh City, aged 73.
A scholarship for Young Vietnamese Mathematics Talents was named after him. He was the first Modern Mathematician of Vietnam to have his name used for a street.
