Lajos Martin (30 August 1827 – 4 March 1897) was a Hungarian mathematician and engineer, known by his works in transportation and aerodynamics. Life and work. He was the seventh son of a wine grower.

From 1863 to 1868 he was teaching at secondary schools in Selmecbánya and Pressburg and he wrote some textbooks on mathematics in this level. In 1872 he was appointed professor of mathematics in the university of Kolozsvár. He became rector of the university in 1895–1896 and in his inaugural discourse he spoke about the importance of flights in the transportation of people and goods. He began his research in ballistics in the army, and he followed his theoretical and experimental works  in this area all his life. He became also interested in hydraulics and in the search of the most efficient propeller. In his last years he worked in aerodynamics and he had a very clear idea about aviation would be in the future.
