Margaret Brown (née Tobin) (July 18, 1867 – October 26, 1932) was an American socialite, philanthropist, and activist who became famous because of her survival of the 1912 sinking of the RMS Titanic, after exhorting the crew of Lifeboat No. 6 to return to look for survivors. It is unclear whether any survivors were found after Lifeboat No. 6 returned to search. She became known after her death as "The Unsinkable Molly Brown", although during her life, her friends called her "Maggie".
