Bob Ross was a Master Sergent in the US Airforce. He was required to be “mean and tough,” to be “the guy who scream at you for being late to work.” After 20 years he left the military and decided “he would never scream again.” 3 years later he started “The Joy of Painting”.
Bob Ross never received any money for his show, The Joy of Painting. His company, Bob Ross Inc., sold art supplies, how-to videos, and he gave art lessons.
When the Mona Lisa was stolen from the Louvre in Paris in 1911, one of the people arrested on suspicion of its theft was Pablo Picasso. He’d been implicated by his friend, the poet Guillaume Apollinaire; both men were questioned, and eventually released.
