Stan Lee
The iconic comic book writer Stan Lee joined the industry when he was only 17 years old. Back then he began working as an assistant in the comic book department for the company called Timely Publications. However, even after he was promoted from filling inkwells and erasing pencil marks to running the department it took him some time to become a success. Stan Lee published his first comic book hit only in 1961 when he was almost 39 years old.
