Ernest Lucas, secretary of the Rubelmann-Lucas Hardware Company of St. Louis, was born in Gasconade county, Missouri, on the 2d of February, 1860, and is a son of George and Amelia (Prosch) Lucas. He supplemented his public school education by study in Johnson's Business College and thus qualified for the active and responsible duties of life. He started upon his business career as a salesman in his father's grocery store in 1877 and after three years' preliminary training there of a thorough character he came to St. Louis in 1880 and entered the employ of Rubelmann & Company, hardware dealers, and through the intervening period of forty years has been associated with the business. In July, 1885, upon the incorporation of the RubelmannLucas Hardware Company, he became one of the directors and the secretary and has continued in this official connection with the business. He is a member of the Missouri Athletic Association, also of the Liederkranz Club and he largely finds his recreation in fishing, but the major part of his time and attention is concentrated upon his business affairs and the house of which he has now been a representative for four decades largely stands as a monument to his keen business discrimination and indefatigable energy.
