1926 Rudolph Valentino, age 31 – Silent screen idol (The Four Horsemen of the Apocalypse, The Sheikh, Blood and Sand, The Eagle) His death, from a perforated ulcer, sent his fans into an hysterical state of mass mourning. Tens of thousands of people paid tribute at his open coffin in New York City, and 100,000 mourners lined the streets outside the church where funeral services were held. Valentino's body then travelled by train to Hollywood, where he was laid to rest after another funeral

Supposedly, there was a "lady in black" who'd visit his grave on the anniversary of his death. I'll have to look it up. I wonder if the last paragraph is true.
Interesting:

Ditra Flame, who said she was the original ''Lady in Black'' who for decades made an annual pilgrimage to leave a rose at the grave of Rudolph Valentino, has died. She was 78 years old.

Miss Flame, who never married, was buried Tuesday in San Jacinto, Calif. Miss Flame, who pronounced her name flah-MAY, died in Ontario, Calif., last week. She was found alone in a house cluttered with Valentino memorabilia.

When she was 14, according to an account Miss Flame told many times, she was deathly ill. Several times Valentino, as a favor to her mother, went to her hospital bedside and placed a red rose in her hand.

''You're not going to die at all,'' he was said to have told her. ''You are going to live for many more years. But one thing for sure, if I die before you do, please come and stay by me because I don't want to be alone.''
