The needs of his times, and of the people among whom he lives, have often set the inventor’s mind working along the line of his achievement. It was so with Elias Howe, who built the first sewing-machine. A hard-working man, and not overstrong, he would return to his home from the machine-shop where he was employed, and throw himself on the bed night after night to rest. Each night he watched his young wife sewing to clothe their three children and add a little something to the family income. With a strong taste for mechanics it was natural that he should wonder if there were not some way of lightening the burden of so much needlework.
