Henry Ford revolutionized the automotive industry by developing the assembly line process for building his cars. A little interesting sidebar to this story is his selling of charcoal briquettes. Ford did not invent the charcoal briquette but was the first to mass produce and sell. He had a lot of leftover scrap wood/sawdust from his sawmill that made lumber for his Model T's. He found out adding tar and cornstarch to charcoal and pressed would make briquettes. Edward G Kingsford was a real estate agent who was related to Ford by marriage to a cousin Minnie. He ended up running Fords charcoal briquette plant. Fast forward 100 years and you may have a blue bag on your patio.
