Fontaine was the third son of Gaspard-Théodore-Ignace de la Fontaine,[3] who was appointed Governor of Luxembourg in 1841, and subsequently served as the country's first Prime Minister in 1848. Fontaine studied law at Liège, and spent a further year at Heidelberg pursuing Germanic studies from 1844 until 1847,[4] before becoming a lawyer in 1850. Fontaine was not a skilled speaker, and this may be the reason why he later left the bar and became a deputy judge, then worked as an office manager for the railways.[3] In 1858, he opened a weaving business, employing 60 workers in Remich.[3] From 1867 until 1870, he served as mayor of Stadtbredimus, in eastern Luxembourg's Moselle Valley, and served as a Justice of the Peace in Vianden from 1881 and 1889.[5] He lived in Stadtbredimus Castle from 1858 to 1881 where he would live for the last decade of his life.
