Bread used to take a very long time to make. You didn't want to run out early either so you made lots of it. Even with so many loaves you still ran out fast.

Otto knew that this was happening and you could already buy pre baked loaves at the bakeries but those were still uncut. That's when he saw the money making opportunities of a life time that would revolutionize the world.

The reason he did it was for the fame the money, but he also did it to help out house wives of America. Even then they didn't have too many jobs for woman so being a house wife is all they could do.
