Alexis 'Lexi' Brasseur (26 December 1860 – 3 November 1924) was a Luxembourgeois playwright, composer, and metallurgist. Born in Luxembourg City as the oldest son of Dominique Brasseur, Brasseur attended the Athénée de Luxembourg. He followed this by studying law at the University of Bonn, where he met Batty Weber. Brasseur received his doctorate in Luxembourg in 1886, and was called to the bar, but showed little interest in working in the law. He turned to metallurgy, like his father and uncle Pierre.
