Heilmann had for some years been diligently studying the contrivance of a machine for combing long-stapled cotton, the ordinary carding-machine being found ineffective in preparing the raw material for spinning, especially the finer sort of yarn, besides causing considerable waste. To avoid these imperfections, the cotton-spinners of Alsace offered a prize of 5000 francs for an improved combing-machine, and Heilmann immediately proceeded to compete for the reward. He was not stimulated by the desire of gain, for he was comparatively rich, having acquired a considerable fortune by his wife. It was a saying of his that "one will never accomplish great things who is constantly asking himself, how much gain will this bring me?" What mainly impelled him was the irrepressible instinct of the inventor, who no sooner has a mechanical problem set before him than he feels impelled to undertake its solution. The problem in this case was, however, much more difficult than he had anticipated. The close study of the subject occupied him for several years, and the expenses in which he became involved in connexion with it were so great, that his wife's fortune was shortly swallowed up, and he was reduced to poverty, without being able to bring his machine to perfection. From that time he was under the necessity of relying mainly on the help of his friends to enable him to prosecute the invention.
While still struggling with poverty and difficulties, Heilmann's wife died, believing her husband ruined; and shortly after he proceeded to England and settled for a time at Manchester, still labouring at his machine. He had a model made for him by
