Lieven Gevaert (born in Antwerp, 28 May 1868 – died in The Hague, 2 February 1935) was a Flemish industrialist. His father died when he was only three years old. He started his career in the company he founded together with his mother in 1889, which produced photographic paper according to traditional methods.
In 1894, he founded the company Gevaert & Co, which in 1920, was transformed to N.V Gevaert Photo-producten and later became Agfa-Gevaert N.V.
Already at an early age he felt socially responsible and wanted to advance the status of the Flemish language in Belgium. His personal ideas were strongly influenced by the social encyclical Rerum Novarum (1891) and the writings of Lodewijk De Raet. He supported several Flemish initiatives as a manager, but stayed outside of politics. His main objectives were the introduction of Flemish (Dutch) as a business language, and the foundation of a sound Dutch-speaking education as a means to establish a Flemish elite.
When in 1926, the Vlaamsch Handelsverbond (Vlaams Economisch Verbond, VEV) was founded, Gevaert was its first chairman. Later he founded the Sint-Lievenscollege in Antwerp.
