The Metropolitan Museum of Art in New York City is looking for a new exhibit to honor the greatest inventors of the modern world and their inventions. You and a team of collegues need to decide which four inventors have made the greatest contribution to the world as we know it today. The inventions of these men and women will be displayed in a virtual exhibit (PowerPoint Presentation) along with a biographical essay of each inventor to submit to the Metropolitan Museum of Art in New York City, New York.   You must have at least 10 inventions to display in your exhibit (the actual invention or a picture of it) along with a five paragraph biographical essay of each of the four inventors.
