Dimitrie Pompeiu (October 4, 1873, Broscǎuţi, Botoşani – October 8, 1954, Bucharest) - orthodox christian, and one of the greatest Romanian mathematicians. He is remembered in the mathematical world for numerous contributions such as: the set distance  that he introduced in his 1905 Université de Paris dissertation published in the same year in the Annales de la faculté des sciences de Toulouse (a set distance was introduced in a slightly different form in 1914 by Hausdorff, who credited Pompeiu's definition though), his contributions in complex analysis, including the areolar derivative  and the seminal Cauchy-Pompeiu's formula (higher dimensional analogues of the Cauchy-Pompeiu formula are topics of current research, while the formula was used in the theory of functions of several complex variables by Dolbeault and Grothendieck ), and for the celebrated Pompeiu's Conjecture that he formulated in his 1929 C. R. Acad. Sci. Paris article , a conjecture not fuly proved yet. Still, elegant analogues of Pompeiu's Conjecture continue to be proved in other areas  - this is an indicator of the fertility of the idea.
