Egide Walschaerts (21 January 1820 – 18 February 1901) was a Belgian mechanical engineer, best known as the inventor of the Walschaerts valve gear for use in steam locomotives. He was born in Mechelen, Belgium. In 1838 he was recognised as an excellent modeller, presenting his work at a local exhibition in Mechelen. Minister Rogier, who opened the exhibition, was so impressed that he arranged a place for Walschaerts at Liège University. ==Career== In 1842 he joined the Belgian State Railways and two years later had reached the rank of foreman. He was made chief superintendent of the works shortly after but mysteriously, for such a meteoric early career, never rose any higher. He held this position for the rest of his life, first at Mechelen and then at Brussels South.
