On September 17th of 1925 Frida Kahlo suffers near-fatal injuries in a bus accident in Mexico, causing her to abandon her medical studies and take up art.
Her taking up art was fortuitous, as she became one of the greatest artists of our time and a personal favorite. But she had a rough life, with her painful injuries and repeated (botched) surgeries combined with her husband’s (Diego Rivera) infidelities. She died at only 47. A Kahlo painting, “Self portrait with thorn necklace and hummingbird” 
A bit surprising the U.S. government issued a stamp of her in 2001 even though she was an avowed communist and personal friend of Leon Trotsky.
