Marilyn Monroelived a life in the spotlight, which her sister Berniece Baker Miracle documented in the only authorized biography of the star’s life.
In 1994, Miracle publishedMy Sister Marilyn: A Memoir of Marilyn Monroe,which she co-wrote with her daughter Mona Rae Miracle. The book details how the sisters bonded despite their estrangement as kids and the effects ofMonroe’s fame.
Despite much of Monroe’s life being in the public eye, she rarely spoke about her sister. Miracle was born in 1919, seven years before Monroe, to the same mother as the Hollywood star. The pair didn’t meet until Monroe was 18, but they formed a close bond.
“She was a wonderful sister,” Miracle toldThe New York Timesin 1994.
Here is everything to know about Marilyn Monroe’s sister.

Miracle was born to Gladys and Jasper Baker on July 30, 1919, in Venice, California.
They met when Monroe was 18
According toThe New York Times,the sisters didn’t find out about each other until 1938, when Monroe was 12 and Miracle was 19.
At the time, the elder sister was married to Paris Miracle, and about to become a mother. Monroe was livingbetween family friends, foster parents and an orphanage, so the sisters didn’t meet until 1944.
After they met in person, Monroe wrote a postcard to Miracle and her husband. “I just can’t tell you both how I enjoyed meeting you,” she wrote. “I want to thank you for everything, I had a wonderful time. Love, Norma Jeane.”
Despite Monroe’s work and travel schedule, the sisters stayed in touch

In a 33rd birthday card Miracle sent to Monroe in 1959, she wrote about wanting to get together soon.
“Dearest Marilyn, I’d love to fly up and visit you this summer during part of my vacation,” Miracle wrote in the card, which is displayed in the digitalMarilyn Monroe Collection. “Please phone or write me as to when you will be home, and the best time to come. Give my regards to Arthur. Love, Berniece.”

WhenMonroe died in 1962, her ex-husbandJoe DiMaggio, business manager Inez Melson and Miracle all worked together to plan her funeral.
Miracle toldTheNew York Timesthat she chose Monroe’s casket in addition to the green dress the actress was buried in. PerEntertainment Weekly, Miracle’s book details how she cobbled together ”safety pins, a sheet, and several garments of various sizes and thicknesses — to be used in making the dress conform to Marilyn’s normal body shape” so that the actress would look like herself.
To manage the crowds they expected at Monroe’s services, Miracle, DiMaggio and Melson didn’t invite many of Monroe’s Hollywood friends and released a statement to explain.
“We sincerely hope that the many friends of Marilyn will understand that we are deeply appreciative of their desire to pay last respects to Marilyn whom we all loved,” they wrote. “We hope that each person will understand that last rites must of great necessity be as private as possible so that she can go to her final resting place in the quiet she has always sought.”
