4. Marilyn Monroe – Smarter Than You Think
The iconic Marilyn Monroe spent her career profiting off the stereotype of the dumb blonde with movies such as Gentlemen Prefer Blondes and The Seven Year Itch. From her diaries, interviews and love of reading we know that this stereotype was far from true regarding Marilyn herself.
It must have been very difficult for a woman as intelligent as Monroe to have to dumb herself down to achieve success. Her marriage to the famous playwright Arthur Miller unfortunately seemed to only distract her further from her own intelligence.
