Mumtaz Begum Jehan Dehlavi, later known as Madhubala, was born in New Delhi, on February 14, 1933. She was the fifth of 11 children in a conservative Pathan family.
In the short time that she ruled the silver screen in India, Madhubala achieved the kind of iconic status that many actors can only dream of. Often compared to another ethereal beauty, Marilyn Monroe, who also died young, hers was a life full of great professional highs but also many personal lows. The magic of Madhubala continues to enthral cinema lovers all over the world. She would have been 83 today.
In a routine check up, it was discovered that Madhubala had a hole in her heart. Her ailment was kept secretive from the film industry. The doctors refused to operate on her, as there was virtually no hope of survival. The doctors said that even if the operation is successful, she won’t live for more than a year. It was at that point of time that, she realized that she shouldn’t have married Kishore Kumar. She passed away on the February 23, 1969.
