Ion Ghica
Ion Ghica (August 12, 1816-May 7, 1897) was a Romanian revolutionary, mathematician, diplomat and twice Prime Minister of Romania (between 1866 and 1867, and between 1870 and 1871). He was a full member of the Romanian Academy and its president for four times (1876-1882, 1884-1887, 1890-1893 and 1894-1895). He was the older brother and associate of Pantazi Ghica, a prolific writer and politician.
After finishing his studies in Paris, he left for Moldavia and was involved in the Francmasonic Fratia ("Brotherhood") conspiracy of 1848, which was intended to bring about the union of Wallachia and Moldavia under one native Romanian leader, Prince Mihai Sturdza. Ion Ghica became a lecturer on mathematics at the Academy which was founded by the same Prince Sturdza in Iasi (future University of Iasi).
