Today, 100,000 Americans can trace their ancestry back to the immigrants that came through Ellis Island. Steel is too expensive to buy for buildings. Andrew Cunning saw a new way of making steel. Steel was strong enough to allow buildings to be built taller. Cars, buildings, airplanes, etc cannot be built without steel. Cunning gambled for steel right about the time of the Great Depression. Luckily, it works and he becomes rich from the steel production. Builders for tall skyscrapers must "walk the steel" 30 stories above the ground. Novices can be dangerous to all. The men were up there for 8 hours a day, meals when they can, no bathroom breaks. $4 pay per day. 2 out of 5 men die or are disabled on the job. Before the elevator, stories in buildings stopped at 5 stories. In 1890, crime and poverty lined the streets. Using photography for police work will change police work forever. In cities, slums are crammed into small rooms, human waste was thrown on the streets. Jacob A. Reicks used the first flash for a camera using a special gunpowder that created enough light to shoot a picture in the dark. In NYC alone, over 40,000 people die each year because of filth. Thomas Edison, inventor, entrepreneur, created the first electric light bulb. A piece of carbonized cardboard burned for 3oo hours.
