At age 22, he runs away from home and become an actor. An actor does not make much money, so Isaac also learns to be a mechanic. When he needs money, he works as a mechanic.
    Now it is 1851. Singer is working as a mechanic in Boston. Someone tells him he can make a lot of money if he can make a good sewing machine. Singer needs money. There are already several kinds of sewing machines. But none of them work well. In eleven days, Singer makes the first sewing machine that really works.
    Singer and two other people stag the I. M. Singer Company. They make sewing machines. Soon everyone wants to buy one. The singer Company uses a great new idea to sell its machines. People do not have to pay all the money at one time. They can pay a little money every month or every week.
